Description:
INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS 
     Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are incorporated by reference under 37 CFR 1.57 and made a part of this specification. 
     BACKGROUND 
     Field of the Inventions 
     This application relates to climate control, and more specifically, to climate control of a bed or similar device. 
     Description of the Related Art 
     Temperature-conditioned and/or ambient air for environmental control of living or working space is typically provided to relatively extensive areas, such as entire buildings, selected offices, suites of rooms within a building or the like. In the case of enclosed areas, such as homes, offices, libraries and the like, the interior space is typically cooled or heated as a unit. There are many situations, however, in which more selective or restrictive air temperature modification is desirable. For example, it is often desirable to provide an individualized climate control for a bed or other seating device so that desired heating or cooling can be achieved. For example, a bed situated within a hot, poorly-ventilated environment can be uncomfortable to the occupant. Furthermore, even with normal air-conditioning, on a hot day, the bed occupant&#39;s back and other pressure points may remain sweaty while lying down. In the winter time, it is highly desirable to have the ability to quickly warm the bed of the occupant to facilitate the occupant&#39;s comfort, especially where heating units are unlikely to warm the indoor space as quickly. Therefore, a need exists to provide a climate-controlled bed assembly. 
     SUMMARY

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     This application is generally directed to climate control systems for beds or other seating assemblies. The climate control system and the various systems and features associated with it are described herein in the context of a bed assembly because they have particular utility in this context. However, the climate control system and the methods described herein, as well as their various systems and features, can be used in other contexts as well, such as, for example, but without limitation, seat assemblies for automobiles, trains, planes, motorcycles, buses, other types of vehicles, wheelchairs, other types of medical chairs, beds and seating assemblies, sofas, task chairs, office chairs, other types of chairs and/or the like. 
     The various embodiments described and illustrated herein, and equivalents thereof, generally disclose improved devices, assemblies and methods for supplying ambient and/or thermally conditioned air or other fluids to one or more portions of a bed assembly. As discussed in greater detail herein, as a result of such embodiments, air or other fluids can be conveyed to and/or from an occupant in a more efficient manner. Accordingly, undesirable fluid losses can be reduced or minimized as the air or other fluids are transmitted through the various components of the climate controlled bed. For example, the use of spacers (e.g., spacer fabrics or other materials), comfort layers (e.g., quilt layers), sew seams, stitching, hot melt barriers, engineered materials, flow diverters, passageways, inserts, fabrics and other impermeable members and/or the like, either alone or in combination with each other, can help provide a more targeted fluid stream to one or more portions of a bed. In addition, the arrangements disclosed herein can help reduce or minimize thermal losses as fluid is delivered to or from one or more occupants of a bed or other seating assembly. Thus, more uniform thermal coverage can be advantageously provided. 
     Various features and aspects of the embodiments disclosed herein are particularly useful in climate-controlled beds and similar devices, such as, for example, air chamber beds, adjustable beds, inner-spring beds, spring-free beds, memory foam beds, full foam beds, hospital beds, other medical beds, futons, sofas, reclining chairs, etc. However, such features and aspects may also be applied to other types of climate control seating assemblies, such as, for example, automobile or other vehicle seats, office chairs, sofas and/or the like. 
     With reference to the schematic illustration of  FIG. 1A , a bed  10 A can include a lower portion  20  (e.g., box spring, foundation, etc.) and an upper portion  40  (e.g., mattress). In some embodiments, the lower portion  20  and upper portion  40  are separate members that are configured to be positioned adjacent to each other. As discussed in greater detail herein, the lower and upper portions  20 ,  40  can be removably or permanently secured to each other using one or more connection devices or methods. The lower portion  20  can be configured like a box spring or other structure member for supporting the upper portion  40  positioned above it. In some embodiments, as illustrated in  FIGS. 15-18 , two or more lower portions  20  can be used to support a single upper portion  40 . In other arrangements, the bed  10 A can include more or fewer portions, layers, features and/or other members, as desired or required by a particular application or use. For example, the bed  10 A can include a pillow-top portion (not shown) generally positioned along the upper surface of the top portion  20 . 
     In other embodiments, one or more intermediate layers are generally positioned between the lower portion  20  and the upper portion  40 . Such intermediate layers can be provided to reduce the likelihood of movement between the upper and lower portions  40 ,  20 , to reduce fluid losses through the interface of the upper and lower portions or through retrograde fluid flow (e.g., downwardly, in the direction of the lower portion), to help maintain one or more components of the bed assembly at certain desired location and/or for any other purpose. The intermediate layer can extend continuously or substantially continuously between the upper and lower portions  40 ,  20 . Alternatively, as discussed in greater detail herein with reference to  FIG. 14 , such an intermediate layer or member (e.g., felt scrim) can be intermittently positioned between the upper and lower portions  40 ,  20 . In some arrangements, the intermediate layer is secured to the upper portion  40  and/or the lower portion  20  using adhesives, fasteners and/or any other connection method or device, as desired or required. 
     As illustrated in  FIG. 1A , the lower portion  20  can include one or more fluid modules  100  that are adapted to provide temperate-conditioned (e.g., heated, cooled, etc.) air or other fluid to one or more portions of the bed  10 A. In the depicted cross-sectional view, the bed  10 A comprises two fluid modules  100 . In other arrangements, more or fewer fluid modules  100  can be included, as desired or required. The fluid modules  100  can selectively heat or cool air or other fluid that is being delivered through the bed  10 A toward one or more occupants. However, the fluid modules  100  can be configured to deliver ambient air or fluid toward or away from one or more occupants without performing any thermally conditioning at all. Further, the level of heating, cooling and/or other fluid conditioning can be selectively controlled as desired by a user. For example, as discussed in greater detail herein with reference to  FIGS. 8A-11D, 31 and 32 , a climate control bed can include two or more separate zones, such that each zone can be selectively adjusted by an occupant, as desired or required. In alternative embodiments, the fluid modules  100  can be configured to draw air or other fluids away from the top of the bed  10 A, either in lieu of or in addition to being configured to deliver fluids toward the top of the bed  10 A. 
     The fluid module  100  can include a fluid transfer device  102  (e.g., blower, fan, etc.), a thermoelectric device or TED  106  (e.g., Peltier device), a convective heater, a heat pump, a dehumidifier and/or any other type of conditioning device, conduits to place the various components of the fluid module  100  and other portions of the bed  10 A in fluid communication with each other and/or the like. In addition, the lower portion  20  can include one or more inlets and outlets (not shown) through which air or other fluid can enter or exit an interior space  21  of the lower portion  20 . Accordingly, as described in greater detail herein, once air or other fluid enters the interior space  21  of the lower portion  20  (e.g., through one or more inlets), it can be directed toward the upper portion  40  by one or more fluid modules  100 . As noted above, in any of the embodiments disclosed herein, or equivalents thereof, the fluid module  100  includes a heating, cooling and/or other conditioning (e.g., temperature, humidity, etc.) device that is not a thermoelectric device. For example, such a conditioning device can include a convective heater, a heat pump, a dehumidifier and/or the like. Additional information regarding convective heaters is provided in U.S. patent application Ser. No. 12/049,120, filed Mar. 14, 2008 and published as 
     U.S. Publication No. 2008/0223841, and U.S. Provisional Patent Application No. 61/148,019, filed Jan. 29, 2009, the entireties of which are hereby incorporated by reference herein. 
     Further, in any of the embodiments disclosed herein or equivalents thereof, a fluid module can be in fluid communication with one or more fluid conditioning devices, such as, for example, thermoelectric devices, convective heaters, heat pumps, dehumidifier units and/or the like. Such devices can be incorporated into a fluid module, may be physically (e.g., directly or indirectly) or operatively attached to a fluid module and/or may simply be in fluid communication with a fluid module. For example, in one arrangement, a climate controlled bed assembly includes a dehumidifier unit that is configured to remove an undesirable amount of humidity from the air or other fluid being drawn into one or more inlets of the assembly&#39;s climate control system. 
     Accordingly, the amount of condensation forming within the thermoelectric device (and/or any other thermal conditioning device) can be advantageously reduced. Such a dehumidifier unit can be located within a fluid module. Alternatively, a dehumidifier can be placed upstream and/or downstream of the fluid module. In fluid module arrangements that comprise a thermoelectric device, a dehumidifier located upstream of the fluid module can help reduce the likelihood of potentially damaging and/or disruptive condensate formation within the thermoelectric device. The dehumidifier unit and/or any other conditioning devices can be positioned within the foundation (or lower portion of a bed), within the mattress (or upper portion of a bed) and/or at any other component or location, either within or outside the bed assembly. Additional information regarding condensate detection, removal and related concepts is provided in U.S. patent application Ser. No. 12/364,285, filed Feb. 2, 2009, the entirety of which is hereby incorporated by reference herein. 
     In embodiments where a fluid module comprises (or is in fluid communication with) a thermoelectric device or similar device, a waste fluid stream is typically generated. When cooled air is being provided to the bed assembly (e.g., through one or more passages through or around the upper portion), the waste fluid stream is generally hot relative to the main fluid stream, and vice versa. Accordingly, it may be desirable, in some arrangements, to channel such waste fluid out of the interior of the lower portion  20 . For example, the waste fluid can be conveyed to one or more outlets (not shown) or other openings positioned along an outer surface of the lower portion  20  using a duct or other conduit. Additional details regarding such arrangements are provided herein with relation to  FIGS. 15A-15C . In arrangements, where the lower portion  20  comprises more than one thermoelectric device, the waste fluid streams from two or more of the thermoelectric devices may be combined in a single waste conduit. 
     With continued reference to  FIG. 1A , the upper portion  40  of the bed  10 A can include one or more types of core designs. For example, the core  60  can comprise one or more foam portions, filler materials, springs, air chambers (e.g., as used in an air mattress) and/or the like. According to certain arrangements, the upper portion  40  comprises a modified standard spring mattress. As illustrated in  FIG. 1A , in some embodiments, the core  60  comprises one or more fluid passageways  52 , openings or other conduits that are configured to place the lower portion  20  (e.g., the fluid modules  100  positioned within an interior space  21  of a box spring, other base or support structure, etc.) in fluid communication with the top of the upper portion  40  and/or any member, layers and/or portions  70 ,  80  positioned above the core  60  (e.g., within one or more foam layers, between springs or other resilient members, etc.). The fluid passageways  52  can be positioned through an interior portion of the core  60 , as shown in  FIG. 1A . Alternatively, one or more fluid passageways can be positioned along a side of the core and/or can be separate items from the core (e.g., configured to deliver air or other fluid around the core). 
     In some embodiments, the core  60  can comprise one or more fluid passageways  52  situated therein. Alternatively, the passageways  52  can be created after the core  60  has been completely or partially formed. Further, the passageways  52  can include a generally cylindrical shape with a generally circular cross-section. In other embodiments, however, the passageways  52  can have a different cross-sectional shape, such as for example, oval, square, rectangular, other polygonal, irregular and/or like, as desired or required. In some arrangements, air or other fluid is directly conveyed within the passageways  52 . However, the passageways  52  can be configured to accommodate an insert  54  ( FIGS. 7A and 14 ) through which fluids are transferred. Such inserts  54  can comprise one or more bellows or other features to help accommodate movement (e.g., compression, expansion, rotation, etc.) while the bed  10 A is in use. In addition, the inserts  54  can reduce the likelihood that air or other fluid being conveyed through the passageways  52  will be inadvertently directed to locations other that the intended target (e.g., pass through a space generally between the upper and lower portions  40 ,  20 , leak into the core  60  or other portions or layers of the upper portion  40 , etc.) or pick up undesirable odors (e.g., from the surrounding foam, latex and/or other materials of the core  60 ) or other substances with which the air or other fluid may otherwise come in contact. In some embodiments, the passageway  52  can include a liner (e.g., fabric liner), coating (e.g., liquid coating), film or other substance or member to help prevent or reduce the likelihood of air or other fluids from passing therethrough. Thus, the use of inserts  54 , liners, coatings, films and/or other features can help reduce the likelihood that air or other fluid will diffuse, penetrate or otherwise permeate to or from the core  60 , through the interior walls of the passageways  52 . The quantity, shape, size, location, spacing and/or other details regarding the passageways  52  can be different than illustrated and described herein, as desired or required by a particular application or use. 
     In some embodiments, the outlet of the fluid module (e.g., the blower, thermoelectric device or convective heater, etc.) is directly or indirectly connected to the insert or other duct that is configured to be routed through the passageway  52  or insert  54 . Thus, the interface of the passageway  52  (or one or more components positioned therein, e.g., an insert  54 ) and the fluid module can comprise a face seal, radial seal, mechanical attachment, coupling, another interface device and/or the like. 
     As illustrated in  FIG. 1A , each passageway  52  is adapted to be aligned and placed in fluid communication with a fluid module  100 . The lower portion  20  and the upper portion  40  can be configured so that the passageways  52  are generally aligned with the outlets or outlet conduits of one or more fluid modules  100  when the lower and upper portions  20 ,  40  are secured to one another or otherwise placed in proper relation to each other. For example, as discussed with reference to  FIGS. 7A and 14 , a fitting  38 ,  38 ′ (e.g., flange), an interconnecting conduit  39 ,  39 ′ and/or other interfacing member can be placed generally between the lower and upper portions  20 ,  20 ′ and  40 ,  40 ′ to ensure that the fluid modules  100 ,  100 ′ are properly aligned (e.g., physically, hydraulically, etc.) with the corresponding passageways  52 ,  52 ′ of the upper portion  40 ,  40 ′. Thus, the use of protruding and/or recessed fittings or features on corresponding surfaces of the upper and lower portions of the bed can facilitate the alignment of the upper and lower portions. As discussed in greater detail herein, such fittings  38 ,  39 , components and/or other devices can also help reduce the likelihood of relative movement between the lower and upper portions  20 ,  40 , especially when the bed is in use. 
     In addition, as discussed with reference to  FIG. 14 , one or more intermediate members  37 ′ can be positioned generally between the upper and lower portions of a climate control bed assembly. For example, in the embodiment of  FIG. 14 , the intermediate member  37 ′ includes a generally circular felt scrim or other layer having a central opening. In some arrangements, the felt scrim or member  37 ′ is approximately 2 mm thick and 155 mm (6.1 inches) in diameter. As shown, the intermediate member  37 ′ can include a central opening, which, in some embodiments, is shaped and sized to generally match the opening size of the adjacent components of the climate control bed (e.g., the flange  38 ′, the interconnecting conduit  39 ′, the insert  54 ′ positioned within the passageway  52 ′, etc.). In other embodiments, the shape, size and other characteristics of the intermediate member  37 ′ can vary, as desired or required. The intermediate member  37 ′ can be configured to secure to an adjacent surface of the upper portion and/or the lower portion of the bed assembly using adhesives (e.g., adhesive strip), fasteners and/or any other connection device or method. 
     Regardless of their exact shape, size and configuration, such scnms or other intermediate members  37 ′ can offer one or more benefits and other advantages. For example, an intermediate member  37 ′ can help maintain the position of the lower end (e.g., flanged end) of the insert  54 ′ during use, thereby preventing undesirable pull-through of the insert  54 ′ into the passageway  52 ′. In addition, such an intermediate member  37 ′ can help reduce the likelihood of leaks as conditioned and/or unconditioned air or other fluid is conveyed from a fluid module toward an occupant. For instance, the intermediate member  37 ′ can be configured to prevent or substantially prevent conditioned air from flowing backwards through the insert toward the interface between the upper and lower portions of the bed assembly. A felt scrim  37 ′ or other intermediate member can be included with any embodiment of a climate controlled bed assembly disclosed herein or equivalents thereof. 
     With continued reference to  FIG. 1A , one or more members  70 ,  80 , layers and/or portions can be positioned on top of the upper portion  40  of the bed  10 A or incorporated as layers along the top end of the upper portion  40 . For instance, the depicted embodiment includes a fluid distribution member  70  comprising a spacer (e.g., spacer fabric) or other material configured to generally distribute fluid (e.g., open cell foam, a member having an open lattice structure, a spacer or other material placed within a bag or other enclosure, etc.). As discussed in greater detail herein with respect to the embodiments illustrated in  FIGS. 12A and 12B , a fluid distribution member can include one or more channels or other conduits through which fluids may be directed. Such channels or other conduits can be configured to distribute air or other fluid to selected portions of the fluid distribution member, and thus, the bed assembly. The channels or other conduits can be formed when the fluid distribution member is being manufactured (e.g., using injection molding, other molding technologies, etc.). Alternatively, the channels or other conduits can be formed after the fluid distribution member has been completed, using one or more forming devices or methods. As noted herein, the upper portion  40  can be configured for any type of bed, including, without limitation, air chamber beds, adjustable beds, inner-spring beds, spring-free beds, memory foam beds, full foam beds, hospital beds, other medical beds, futons, sofas, reclining chairs and/or the like. 
     Regardless of the exact configuration, air or other fluids delivered into such a fluid distribution member  70  from the passageways  52  may be partially or completely dispersed throughout the fluid distribution member  70 . This can help ensure that fluid being delivered by the fluid modules  100  is generally distributed throughout a desired top surface area of the bed  10 A. 
     As illustrated in  FIG. 1A , the bed  10 A can also include a comfort layer  80  (e.g., quilt layer) or other layer or member that is generally configured to enhance an occupant&#39;s comfort. In some arrangements, such a comfort layer  80  is configured to permit fluids to pass through it. According to some arrangements, a comfort layer  80 , such as used in any the embodiments disclosed herein or equivalents thereof, is configured to allow air or other fluids to pass therethrough only when a threshold back-pressure applied to it has been achieved. The terms comfort layer and quilt layer are used interchangeably herein. 
     In addition, under certain circumstances, it may desirable to limit the back-pressure exerted upon a comfort layer  80  to a desired maximum level. Thus, a comfort layer  80  may comprise a desired back-pressure range for a given fluid flowrate. For example, in one embodiment, when an occupant is positioned on top of the bed assembly, the back-pressure, measured at the fluid module (e.g., the blower or other fluid transfer device), can be less than 1 inch of water when the fluid flowrate is 10 scfm. In other embodiments, such a maximum back-pressure can be higher or less than 1 inch of water (e.g., less than 0.01, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.1, 1.5, 2.0, 5.0, 10.0, more than 10.0 inch water, ranges between such values, etc.). The target back-pressure range can depend on one or more factors or considerations, such as, for example, the friction losses through fluid passageways, fittings and other hydraulic components, the types of materials that comprise the various components of the bed, the shape, size and other properties of the various bed components or layers, the types of spacers (e.g., spacer fabric) utilized and/or the like. 
     Limiting the back-pressure and/or fluid flowrate through a comfort layer and/or other components or layers of a climate controlled bed assembly can provide certain advantages. For example, such limitations can ensure a proper feel at the exposed top surfaces of the bed assembly to generally improve the comfort level of an occupant. In addition, such limitations can help reduce the noise created by air or other fluids moving through the climate control bed. In other embodiments, such limitations can help conserve power and lower the operational expenses of the bed assembly. Additional disclosure about noise and vibration abatement features for climate control bed assemblies is provided below. 
     Thus, in some embodiments, once ambient or thermally conditioned fluid has been delivered into the fluid distribution member  70 , it can be directed toward the top surface of the bed  10 A through the comfort layer  80 . In other embodiments, as discussed herein with reference to  FIG. 2 , one or more other layers  68  or members can be selectively included in the upper portion  40  of the bed (e.g., between the core  60  and the bed&#39;s top surface). 
     In the embodiment illustrated in  FIG. 1B , the bed  10 B further comprises one or more flow diversion members  74  generally positioned above the passageways  52  of the core  60  or other location of the bed&#39;s upper portion  40 . As discussed in greater detail herein, such flow diversion members or diverters  74  can help distribute air or other fluid that is directed into the fluid distribution member  70  (e.g., spacer fabric or other material). As shown, the flow diversion members  74  can be positioned above the fluid distribution member (e.g., between the fluid distribution member  70  and the comfort layer  80 ). The flow diversion members  74  can be sized, shaped and otherwise configured to create a desired air flow dispersion pattern within a desired portion of the fluid distribution member  70 . The flow diversion members  74  can comprise one or more air impermeable, semi-permeable or permeable materials, as desired or required. For instance, even if some fluid is permitted to pass through the flow diversion members  74 , the mere presence of the diversion members  74  above the passageways  52  of the core  60  can cause air or other fluid to be deflected in a lateral or generally lateral direction. The terms flow diversion member and flow diverter are used interchangeably herein. 
       FIG. 2  schematically illustrates a cross-sectional view of another embodiment of a climate-controlled bed  10 C. The depicted bed  10 C is similar to the arrangements illustrated in  FIGS. 1A and 1B  and discussed herein, except that it comprises an additional comfort layer  68  or other member between the fluid distribution member  70  and the core  60 . This additional comfort layer  68  or member can be separate from the core  60  or can form a unitary structure with the core  60 . The additional comfort layer  68  can be configured to further enhance the comfort level to a bed occupant. In some embodiments, the additional comfort layer  68  comprises foam (e.g., viscoelastic foam, polyurethane foam, memory foam, other thermoplastics or cushioning materials and/or the like). 
     With continued reference to  FIG. 2 , the additional comfort layer  68  can comprise conduits  69  that generally align and are in fluid communication with the passageways  52  of the core  60 . As discussed herein, according to certain arrangements, the additional comfort layer  68  forms a unitary structure with the core  60 . In other embodiments, however, the additional comfort layer  68  is a separate item from the core  60  that may be attached to it using adhesives, stitching, fasteners and/or any other connection device or method. Thus, air or other fluid can be conveyed through the passageways  52  of the core  60  and the conduits  69  of the additional comfort layer  68  toward the fluid distribution member  70 . From the fluid distribution member  70 , air and/or other fluids can be at least partially laterally dispersed (e.g., with or without the help of flow diversion members  74 ) before exiting toward the top of the bed assembly  10 C (e.g., through one or more comfort layers  80 , other layers or components, etc.). 
     According to certain embodiments, an air impermeable or substantially air impermeable film  71 , layer or other member is generally situated below the fluid distribution member  70 . This can help prevent or reduce the likelihood of air or other fluids from being undesirably conveyed from the fluid distribution member  70  toward the additional comfort layer  68  and the core  60 . In other embodiments, such a film  71  is less air permeable than the comfort layer  80  or other layers positioned on top of the fluid distribution member  70 . The film  71  or other layer can be used in any of the embodiments disclosed herein or equivalents thereof. 
     In other embodiments, as illustrated in  FIG. 2A , the additional comfort layer  68 A includes a plurality of openings  67 A that are configured to extend completely or partially through the depth of the additional comfort layer  68 A. Once such a perforated additional comfort layer  68 A is positioned adjacent to a core  60 , at least some of the openings  67 A can be placed in fluid communication with the passageways  52  of the core. As a result, the openings  67 A can permit air or other fluid to be conveyed from the passageways  52  of the core  60  to the fluid distribution member  70  situated above the additional comfort layer  68 A. This can advantageously simplify the design of the additional comfort layer  68 A as the need to align the conduits  69  ( FIG. 2 ) of the additional comfort layer with the passageways  52  of the core  60  can be eliminated. Instead, a perforated additional comfort layer  68  can be used with cores having different passageway sizes, locations, spacing, orientations and/or other characteristics. 
     The bed&#39;s upper portion  40  (e.g., foam, spring or other type of mattress) can include one or more other layers or members, either in addition to or in lieu of any of the layers or members illustrated or discussed in connection with the various embodiments disclosed herein. Adjacent layers or members of the bed can be attached to each other using one or more connection methods or devices, such as, for example, adhesives, stitching, seams, fasteners and/or the like. In addition, the size, thickness, shape, materials and/or other details of the various layers or members included in the bed can vary, as desired or required by a particular application or use. 
     One embodiment of a lower portion  20  or support member of a climate-controlled bed is illustrated in  FIG. 3A . As shown, the lower portion  20  can include a lower frame  22  and an upper frame structure  24 . In  FIG. 3A , the lower frame  22  includes relatively large, rigid members (e.g., wood, steel, composites, etc.) that generally form the lower end of the bed. The upper frame structure  24  can include a plurality of smaller metal members that are shaped to form a three-dimensional structure. In some arrangements, the upper frame structure  24  is configured to resiliently support a core and other components of the upper portion  40 . 
     With continued reference to  FIG. 3A , one or more fluid modules  100  can be positioned within an interior of the lower portion  20 . The depicted embodiment comprises two fluid modules  100 ; however, more or fewer fluid modules  100  can be included, as desired or required. Further, the fluid modules  100  can be electrically connected to a controller  16  (e.g., control unit) using one or more hardwired and/or wireless connections. As shown, power and control wires extending to and/or from each fluid module  100  can be routed through electrical conduits  18  or other enclosures. In other embodiments, the fluid modules, controllers and/or any other components or portions of the climate control system can be positioned outside the lower portion  20  and/or any other portion of the bed. 
     As illustrated in  FIGS. 3B and 3C , the lower portion  20  can include a covering material  30  along an exterior area. For clarity, only a top area of the lower portion  20  comprises a covering material  30  in  FIGS. 3B and 3C . However, in other arrangements, a covering material  30  can be placed along other areas of the lower portion  20 . For example, the entire exterior surface of the lower portion  20  can include a covering material  30 . The covering material  30  can comprise a fabric, a film and/or the like. In some embodiments, at least a part of the top of the lower portion  20  comprises a covering material  30  that is configured to help reduce movement between the lower portion  20  and the adjacent upper portion (e.g., core). For example, the covering material  30  can include a non-skid or substantially non-skid surface texture or features (e.g., bumps, grooves, etc.). Alternatively, the covering material can comprise one or more non-skid materials (e.g., rubber). Further, the covering material  30  can include one or more openings  34  that are generally aligned with the fluid modules  100  positioned within the lower portion  20 . 
     With reference to  FIGS. 4A and 4B , the fluid modules  100  can be secured to one or more areas of the lower portion  20 . In the depicted embodiment, the fluid module  100  includes supports  108 A,  108 B or other portions or features that are adapted to secure to the frame structure  24 . However, the support  108 A,  108 B or any other portion of the fluid modules  100  can be secured to any other area of the lower portion  20 . In addition, a fluid module  100  can be secured to the lower portion  20  of a bed using any other device or method. In other embodiments, as discussed herein with reference to  FIG. 14 , the lower portion  20 ′ includes a backer board  110  to which one or more components (e.g., fluid module  100 ′, power supply  112 ′, control unit  114 ′, humidity sensor  116 ′, other types of sensors, etc.) of the climate control bed assembly  10 ′ are configured to secure. Additional details regarding such an embodiment are provided below. 
     With continued reference to  FIGS. 3A-3C , air or other fluid can enter the fluid modules  100  through one or more vents or other openings (not shown) located along the lower portion  20  of the bed assembly. Similarly, any waste air or fluid exiting the fluid modules  100  can be directed out of an interior of the lower portion  20  through one or more vents or openings (not shown). In other embodiments, air or other fluids enter into or exit from the interior of the lower portion  20  of the bed through an air permeable layer (e.g., a fabric or other covering material  30 , as discussed herein) and/or any other member. As discussed in greater detail herein with reference to  FIGS. 15A-15C , a foundation or lower portion  120  of a climate controlled bed assembly can be configured to include separate thermal zones for keeping the fluid module&#39;s main conduits generally separate from its waste conduits. As shown in  FIGS. 15B and 15C , in certain embodiments, the bottom portion includes a specially-designed bed skirt  140  to further assist in preserving such thermally-separated zones intact. Additional information regarding such arrangements is provided below. 
       FIG. 5  illustrates an upper portion  40  of a bed  10  positioned on top of a lower portion  20 . As discussed, the lower portion  20  can include a frame  22  and a frame structure  24  generally positioned on top of the frame  22 . In addition, as illustrated in  FIG. 5 , the lower portion  20  can include a plurality of legs  26  or other support members. In some embodiments, one or more of the legs  26  or other support members comprise wheels to facilitate moving the bed  10  relative to the floor. 
     With further reference to  FIG. 5 , the upper portion  40  of the bed can include a core  60  and one or more layers or portions  70 ,  80  positioned thereon. For example, as discussed in reference to  FIGS. 1A, 1B and 2 , a flow conditioning member  70  (e.g., a spacer or other material), a comfort layer  80  (e.g., a quilt layer), flow diversion members  74  and/or any other layer or member can be positioned on top of the core  60 , as desired or required by a particular application. In some embodiments, the upper portion  40  comprises the general structure and characteristics of an inner-spring bed, an air chamber bed, an adjustable bed, a spring-free bed, a memory foam bed, a full foam bed, a hospital bed, another type of medical bed, a futon, a sofa, a reclining chair and/or the like. The arrangement depicted in  FIG. 5  further comprises a user interface device  12  (e.g., a handheld controller) that is operatively connected (e.g., hardwired, wirelessly, etc.) to the fluid modules  100 , a main control unit and/or any other component or device used to operate the bed  10 . 
       FIG. 6  illustrates an exploded view of the bed  10  of  FIG. 5 . As shown, the foundation or lower portion  20  can include a covering material  30  or other layer along its top surface that is configured to contact the upper portion  40  (e.g., core  60 ). The fluid modules  100  positioned within an interior of the lower portion  20  can be placed in fluid communication with passageways  52  ( FIG. 7A ) of the core  60  through one or more openings  34  in the covering material. One or more fittings  38  or other devices can be optionally used to help place the fluid modules  100  in fluid communication with the passageways  52 . In addition, as discussed, such fittings  38  can help ensure that the upper portion  40  (e.g., the core  60 ) does not slide or otherwise move relative to the lower portion  20 . Additional information regarding such fittings and other devices positioned at the interface of the upper and lower portions  40 ,  20  is provided herein with reference to  FIG. 14 . 
     As illustrated in the cross-sectional views of  FIGS. 7A and 7B , each of the passageways  52  of the core  60  can include an insert  54 . Thus, air or other fluid can be conveyed through the passageways  52  either partially or entirely within such inserts  54 . As discussed, this can help reduce the likelihood that air or other fluid will diffuse through the walls of the passageways  52  into the core  60  or other portions of mattress  40  or upper portion of the bed assembly. In addition, the inserts  54  can help prevent air or other fluid being conveyed therein from picking up undesirable odors as it is being conveyed toward the fluid distribution member  70 , the comfort layer  80  and/or any other portion positioned along the top of the upper portion  40 . As shown, the inserts  54  can include bellows or other features that help the inserts  54  flex, compress, stretch and/or otherwise move in response to one or more loads, moments, stresses or other forces imparted on the bed  10 . The inserts  54  and/or any fittings  38  to which the inserts  54  are connected can include flanges or other protruding features that are configured to contact adjacent surfaces of the core  60 , fluid distribution member  70 , the lower portion  20  and/or any other component of the bed. The use of such flanges or other features can help secure the inserts  54  and/or fittings  38  relative to the passageways  52  of the core  60 , and thereby reduce the likelihood of fluid leaks, pull-through of the insert  54  and/or any other undesirable occurrence. 
     With continued reference to  FIG. 7B , the core  60  can include one or more layers  62 ,  64 ,  66 ,  68  or portions. In one embodiment, the core  60  comprises a main foam portion  62  positioned along the lower part of the core  60 . Alternatively, in embodiments where the bed assembly is of the spring mattress type, the core  60  comprises a plurality of innersprings or coils, either in lieu of or in addition to foam and/or other filler materials. Further, the core  60  can have one or more upper layers  64 ,  66 ,  68  that may comprise one or more other types of foam or other materials. The use of different foams or other materials can permit a bed  10  to be manufactured with certain properties (e.g., rigidity, flexibility, comfort, resiliency, etc.), as desired or required. For example, the different layers  62 ,  64 ,  66 ,  68  of the core  60  can comprise high performance foam, viscoelastic foam, memory foam, open-cell foam, closed-cell foam, other types of foam, filler materials, other natural or synthetic materials, spring coils and/or the like. In some embodiments, the core comprises one, two, three or more layers of latex, viscoelastic foam or other viscoelastic materials. In other embodiments, as discussed, the core can comprise air chambers, springs and/or any other types of components or features, as desired or required. 
     In  FIG. 7B , the layers  64 ,  66 ,  68  positioned on top of the main core layer  62  can comprise a high-performance foam, a viscoelastic foam and a soft foam, respectively. In other embodiments, however, a core  60  can include different materials (e.g., filler materials, thermoplastics, air chambers, springs, other natural or synthetic materials, etc.), either in lieu of or in addition to foam. Further, the core can include more or fewer portions, layers and/or materials than disclosed herein. In arrangements where the core  60  comprises two or more portions or layers, such portions or layers can be attached to one another using adhesives, stitching, fasteners and/or any other device or method. For example, m one embodiment, the various layers of the core  60  are hot melted to each other. 
     With continued reference to  FIGS. 7A and 7B , once transferred from the fluid modules  100  through the passageways  52  (e.g., through one or more fittings  38 , inserts  54 , etc.), ambient and/or thermally-conditioned air or other fluid can enter one or more fluid distribution layers  70 . As discussed in greater detail herein, one or more flow diversion members  74  or diverters strategically positioned above the fluid distribution layer  70  can help re-direct at least some of the air or other fluid entering the fluid distribution layer  70  in a lateral or substantially lateral direction. This can help promote a more even flow distribution and dispersion within the fluid distribution member  70 . In some embodiments, the flow diverters  74  can comprise one or more materials, such as, for example, polymeric materials, fabrics and/or the like. In some embodiments, the flow diversion members  74  are configured to allow at least some air or fluid to permeate therethrough. Alternatively, the flow diversion members  74  can be non air-permeable or substantially non air-permeable, as desired or required. 
     The flow diversion members  74  can be attached to the fluid distribution member  70  and/or one or more adjacent layers of a bed assembly  10  using adhesives, stitching and/or any other connection device or method. The quantity, size, shape, orientation and/or other details of the fluid distribution member  70  and/or the flow diverters  74  can vary, as desired or required. For example, according to certain arrangements, a bed comprises no flow diversion members  74 . In other embodiments, one or more other layers or members can be positioned between the fluid distribution member  70  and the flow diversion member  74 . 
     As illustrated in  FIGS. 7A and 7B , one or more comfort layers  80  can be positioned above and/or below the fluid distribution member  70 . In some embodiments, the comfort layer  80  comprises one or more soft materials, such as, open-cell foam, memory foam, other soft foam, down feathers, other natural or synthetic filler materials and/or the like. Such a comfort layer  80  can be air-permeable so that air or other fluids exiting the top of the fluid distribution member  70  can be transmitted therethrough. The thickness, size, orientation relative to other layers of the bed, materials of construction and/or other characteristics of the comfort layer  80  can vary, as desired or required. 
     The various layers or components that are included in the upper portion  40  of the bed (e.g., the core  60  and its various layers  62 ,  64 ,  66 ,  68 , the flow distribution layer  70 , the flow diversion members  74 , the comfort layer  80 , etc.) can be attached to each other using adhesives, stitching and/or any other device or methods. Alternatively, one or more components or layers of the upper portion  40  can be configured to be separate or separable from each other. 
       FIGS. 8A and 8B  schematically illustrate one embodiment of an upper portion  240  of a climate controlled bed assembly  210  having certain features, components and advantages as described herein. In the depicted embodiment, the upper portion  240  comprises a core  260  which includes four internal passageways  252  across its depth. As shown, the passageways  252  can have a generally cylindrical shape. However, the passageways  252  can include any other desired or required cross-sectional shape, such as, for example, square, rectangular, triangular, other polygonal, oval, irregular and/or the like. Further, in some arrangements, the passageways  252  are symmetrically arranged along the core  260 . This can allow the upper portion  240  to be rotated relative to the lower portion (not shown in  FIGS. 8A and 8B ) while still allowing the passageways  252  to generally align (e.g., physically, hydraulically, etc.) with fluid modules positioned within the foundation or lower portion. Alternatively, the passageways  252  of the core  260  can include a non-symmetrical orientation. Further, in other embodiments, the core  260  can include more or fewer than four internal passageways  252 , as desired or required by a particular application or use. In addition, the size, shape, spacing, orientation and/or any other details of the passageways  252  and/or the core  260  can be different than illustrated or discussed herein. 
     According to some embodiments, the number of internal passageways  252  included in an upper portion of a thermally-conditioned bed can be selected based on the various independently-controlled zones that such a bed comprises. Additional disclosure regarding such arrangements is provided herein in relation to  FIGS. 8A-11D, 31 and 32 . 
     As discussed in greater detail herein, the core  260  can comprise one or more materials or components, such as, for example, foam, other thermoplastics, air chambers, coil springs, other resilient members, filler materials and/or the like. Although not illustrated in  FIGS. 8A and 8B , the upper portion  240  can be configured to be selectively positioned on a lower portion (e.g., foundation, box spring, other frame, etc.). As discussed in greater detail herein, when the upper and lower portions of a bed assembly are properly situated relative to each other, the passageways  252  of the core  260  can be configured to generally align with openings in the lower portion so as to place the passageways  252  in fluid communication with one or more fluid modules (e.g., fans, blowers or other fluid transfer devices, thermoelectric devices, convective heaters or other temperature-conditioning devices, etc.). Thus, as shown, ambient or thermally-conditioned air or other fluid can be advantageously conveyed through the passageways  252  and through one or more layers or components situated above the core  260 , toward the top surface of the upper portion. 
     For example, as illustrated in  FIG. 8B , air or other fluid can be directed from the passageways  252  into a fluid distribution member  270  (e.g., spacer material, spacer fabric or other material) or any other member that is generally configured to laterally or substantially laterally distribute fluid (e.g., air) within the interior of the bed, so that such fluid is advantageously directed along a desired top surface of the bed  210 . Once within the fluid distribution member  270 , air or other fluid can pass through one or more layers or members located along the top of the bed  210 . For example, in the embodiment depicted in  FIG. 8B , the upper portion  240  comprises a comfort layer  280  (e.g., quilt layer) that is adapted to allow air or other fluid to diffuse therethrough. As discussed in greater detail herein with respect to other embodiments, the top portion  240  (e.g., mattress) can comprise one or more other comfort layers, fluid distribution members, filler materials, coil springs or other resilient member and/or the like, to achieve a desired feel (e.g., firmness), comfort level, fluid distribution scheme or the like. 
     Another embodiment of a climate controlled bed assembly  310  is schematically illustrated in  FIGS. 9A and 9B . The depicted bed  310  is similar to the one illustrated and described herein with reference to  FIGS. 8A and 8B . However, the upper portion  340  of the bed  310  in  FIGS. 9A and 9B  additionally includes flow diversion members  374  or diverters above each of the fluid passageways  52 . In some embodiments, the flow diversion members  374  comprise a circular shape and are positioned between the fluid distribution member  370  (e.g., spacer, spacer fabric or material, etc.) and a comfort layer  380  (e.g., quilt layer). As shown, such flow diverters  374  can help at least partially deflect air or other fluid entering the fluid distribution member  370  in a generally lateral direction. Accordingly, the air or other fluid can be more evenly distributed within the fluid distribution member  370  before it exits toward the comfort layer  380  and/or other top layers of the bed  310 . As discussed herein with respect to other embodiments, the flow diversion members  374  can be air permeable, partially air-permeable or non-air permeable, as desired or required. 
     With reference to  FIGS. 10A and 10B , the upper portion  440  can be divided into two or more different climate control zones  442 ,  444  or areas. Accordingly, the climate control bed assembly  410  can be configured to separately cool and/or heat each zone  442 ,  444  according to the preferences of its occupant(s). For example, under such an arrangement, if two people are positioned on the bed  410 , each person can separately control the level of heating, cooling and/or ventilation occurring along his or her side of the bed  410 . Thus, in some embodiments, one user heats his or her side of the bed, while another occupant simultaneously cools or ventilates his or her side of the bed. In other arrangements, both users can heat (or cool or ventilate) their respective sides of the bed, but to varying extents. 
     In the embodiment illustrated in  FIGS. 10A and 10B , separate heating and/or cooling zones  442 ,  444  can be created using sew seams, engineered stitching, other types of stitching, glue beads and/or similar features  476 . For example, such sew seams, stitching or glue beads can be used to partially, completely or substantially completely maintain fluid flow within certain portions or areas of the fluid distribution member  470 . Thus, in some arrangements, air or other fluid from one zone  442 ,  444  is generally not permitted to enter an adjacent zone  442 ,  444 . In addition, as shown in  FIG. 10B , seams, stitching, glue beads and/or similar flow blocking features used along the outer edges of a fluid distribution member  470  can help avoid the loss of fluid along the sides of the bed  410 . In other arrangements, as discussed herein with reference to  FIGS. 11A-11D , one or more fluid distribution members can be generally bounded or otherwise framed by a layer or portion that is air-impermeable or substantially air-impermeable. Accordingly, air or other fluid entering such a fluid distribution member is generally not permitted to be laterally conveyed past a particular outer border. 
     With continued reference to  FIGS. 10A and 10B , the individual climate-control zones or areas  442 ,  444  created by the sew seams  476 , stitching, beads or the like are sized to cover most of the area of the bed  410 . However, in other embodiments, the area over which the zones  442 ,  444  extend can be larger or smaller than illustrated in  FIGS. 10A and 10B , as desired or required. Further, in other arrangements, a bed  410  can include more or fewer zones or areas  442 ,  444 . In the depicted embodiment, air or other fluid is supplied to each zone  442 ,  444  by two passageways  452  in the core  460 . Alternatively, more or fewer passageways  452  can be associated (e.g., in fluid communication) with each zone or area  442 ,  444 . As discussed with reference to other embodiments disclosed herein, one or more of the passageways  452  may be separate from the core  460  and/or may be positioned along the outside of or generally around a core  460 . 
     Air or other fluid can diffuse within the fluid distribution member  470  generally up to the outer limits formed by the seams or beads  476  (or any other fluid barrier, such as, for example, an outer frame as illustrated in  FIGS. 11A-11D ). In some embodiments, the sew seams, stitching, beads  476  or any other barrier are configured to allow some fluid to cross into an adjacent zone or area  442 ,  444 . Thus, the seams, stitching, beads or other flow blocking features  476  of the fluid distribution member  470  may be configured to not completely prevent air or other fluids from traversing across the boundaries they generally form. However, if it is important to maintain the zones  442 ,  444  thermally distinct from each other, the fluid distribution member  470  can be configured to prevent or substantially prevent fluid flow across a particular seam, stitching, bead and/or other flow blocking device or feature  476 . This can be especially important for the sew seams, stitching or beads  476  near the middle of the fluid distribution member  470  that separate adjacent zones  442 ,  444 . 
     As illustrated in  FIGS. 10A and 10B , a flow diversion member  474  or diverter can be generally positioned above each fluid passageway  452  of the core  460 . Thus, as discussed herein with respect to other embodiments, a more even distribution of air can be achieved both within and out of each zone or area  442 ,  444 . As with other arrangements, air exiting the top of each zone  442 ,  444  of the fluid distribution member  470  can be directed to and through one or more top layers  480  (e.g., quilt layer, other comfort layer, etc.). 
     The flow diversion and/or blocking techniques described with reference to the embodiments depicted and discussed herein, or equivalents thereof, may be incorporated into any other arrangement of a climate controlled bed assembly. For example, an upper portion of a climate controlled bed can include one or more sew seams, stitches, glue seams, borders and/or the like. As discussed, such features can help direct ambient and/or thermally-conditioned fluids to one or more target regions of the bed assembly. In some embodiments, a user is permitted to selectively control the cooling, heating and/or ventilation effect being provided to his or her portion of the bed assembly. 
     In addition, for any of the embodiments disclosed herein or equivalents thereof, a bed assembly can be selectively operated under one or more desired operational schemes. Such schemes can be based, at least in part, on a timer, one or more sensors (e.g., pressure sensors, temperature sensors, humidity sensors, etc.) and/or the like. Such operational schemes can help conserve power, enhance comfort to an occupant and/or provide other advantages. For example, the bed can be operated according to a desired operational scheme (e.g., with the temperature and/or flowrate of the fluid being delivered to or from an occupant varying based on the passage of time or some other condition). In other embodiments, the bed assembly is operated to maintain a desired temperature or feel along a top surface on which one or more occupants are situated. Thus, as discussed in greater detail herein, the bed can include one or more sensors (e.g., temperature sensors, humidity sensors, other sensors that are configured to detect a fluid property, etc.), a controller, a timer, a user input device and/or the like. 
       FIGS. 11A-11D  illustrate another embodiment of an upper portion  540  of a climate controlled bed  510  having separate heating, cooling and/or ventilation zones  542 ,  544 . As with other arrangements disclosed herein, the depicted upper portion  540  comprises a core  560 , a fluid distribution member  570  and a comfort layer  580 . However, as discussed in greater detail herein, the upper portion  540  can include more or fewer layers or portions and/or completely different layers or portions. In addition, the layers or portions can be differently arranged (e.g., the vertical order), as desired or required. 
     With continued reference to  FIGS. 11B-11D , the fluid distribution member  570  can include a base portion  572  or frame that is configured to be non-air permeable or substantially non-air permeable, especially when compared to the adjacent inlay portions that comprise the climate control zones or areas  542 ,  544 . According to some embodiments, the base portion  572  comprises closed cell foam and/or any other material having relatively high back pressure properties (e.g., dense foam, other types of foam, fabric, film, etc.). As shown, the fluid distribution member  570  can include one, two or more openings or recesses along its top surface into which inlay portions or members  574  may be positioned. The inlay portions  574  can include a spacer (e.g., spacer fabric) and/or other air-permeable material that is configured to help distribute air within the recess of the base portion  572 . In some arrangements, the inlay portions or members  574  are sized, shaped and otherwise configured to snugly or substantially snugly fit within the recesses of the base portion  572 . Alternatively, the inlay portions or members  574  can extend across only a portion of the recesses. Further, the inlay portions or members  574  can be secured to the base portion  572  using adhesives, fasteners and/or any other device or method. 
     For any climate controlled bed assemblies disclosed herein, or equivalents thereof, in accordance with certain embodiments, as illustrated in  FIG. 11D , the recesses extend only partially through the depth of the fluid distribution member  570 . However, in other arrangements, the recesses extend across the entire depth of the fluid distribution member  570 . As a result, the inlay portions or members  574  can be configured to have substantially the same depth or thickness as the fluid distribution member  570  into which they are secured. 
     According to some embodiments, the fluid distribution member  570  additionally comprises a carrier layer  576  (e.g., fabric, film, etc.) or other member along its bottom surface. Such a carrier layer  576  can be air impermeable or substantially air impermeable, and thus, help prevent or reduce the likelihood of air or other fluid from undesirably escaping the upper portion  540  through the bottom of the fluid distribution member  570 . Accordingly, the base portion  572  and/or the carrier layer  576  can include one or more openings  578  through which air or other fluid being conveyed into the inlay portions  574  of the fluid distribution member  570  may pass. However, in embodiments where the recesses extend through the entire depth of the fluid distribution member  570 , such openings  578  may not be present. 
     Once within the inlay portions  574 , air or other fluid can diffuse laterally within some or all of the fluid distribution member, before being directed toward and through one or more layers positioned above the fluid distribution member  570 . For example, in the embodiment illustrated in  FIGS. 11A-11D , the air or other fluid passes through a comfort layer  580  before exiting the top the bed  510 . As discussed herein, the upper portion  540  can include additional comfort layers and/or any other layers or members. Such additional layers or members can be positioned above and/or below the fluid distribution member  570 , as desired or required. Further, as noted above, the outer frame or border created by the shape of the base portion  572  can help confine air or fluid within a specific inlay portion  574 , and thus, a target area of the bed. 
     Accordingly, a bed  510  can advantageously include one, two or more separate climate control zones  542 ,  544 , allowing a user to selectively heat, cool and/or ventilate one or more areas of the bed  510  according to his or her own preferences. Each zone  542 ,  544  can be in fluid communication with one or more fluid modules (e.g., fan, blower, other fluid transfer device, thermoelectric device, convective heater, etc.). For example, as discussed herein with respect to other embodiments, the fluid modules can be positioned within or otherwise incorporated into an interior space of a foundation or other lower portion of the bed. For example, as discussed herein with reference to  FIG. 14 , the various components of a climate control system can be secured to a backer board  110  or other rigid or semi-rigid surface of the foundation). Such integration of the various climate control components of a bed assembly can provide certain advantages, including, without limitation, facilitating manufacture, shipping, assembly and installation, reducing costs, simplifying the overall design of the system and/or the like. 
     Further, as illustrated and discussed with reference to other arrangements disclosed herein, the fluid modules can be placed in fluid communication with one or more fluid distribution members  570  (e.g., spacer fabrics, porous foam, open lattice structures, etc.) using one or more passageways routed through, around or near the upper portion  540  (e.g., the core  560 , other layers, etc.). According to certain embodiments, each climate control zone  542 ,  544  can be advantageously configured to receive thermally-conditioned and/or ambient air or other fluid from one, two or more different fluid modules (e.g., a blower or other fluid transfer device, a thermoelectric device, a convective heater, etc.), as desired or required. Alternatively, a fluid module can be adapted to provide ambient and/or thermally conditioned air or other fluid to one, two or more different zones  542 ,  544  of abed. 
     With continued reference to  FIGS. 11A-11D , a bed  510  can include a total of four passageways  552  that are routed through an interior portion of the core  560 . In the illustrated embodiment, each inlay portion  574  (e.g., spacer, spacer fabric or other material) is configured to receive air or other fluid from two passageways  552 . However, in other arrangements, an inlay portion  574  can be in fluid communication with more or fewer passageways  552 . 
     As illustrated in  FIG. 11E , air or other fluid can be directed to a fluid distribution member  570 ′ using one or more exterior passageways  552 ′. For example, an externally routed passageway  552 ′ can be used to place each inlay portion  574 ′ (e.g., spacer, spacer fabric or other material, etc.) of the fluid distribution member  570 ′ in fluid communication with one or more fluid modules (not illustrated). Such configurations help eliminate the need for passageways that are routed through an interior of the core  560 ′ or other region of the upper portion  540 ′. As a result, the manufacture, assembly and/or other activities related to providing a climate controlled bed assembly can be simplified. In the depicted embodiment, a separate external passageway  552 ′ is used to deliver ambient and/or thermally conditioned fluid to each inlay portion  574 ′. However, in other embodiments, a passageway  552 ′ can be configured to supply air or other fluid to two or more different inlays  574 ′ or other portions of the bed  510 ′. Further, two or more passageways  552 ′ can be placed in fluid communication with a single inlay  574 ′. As with other arrangements illustrated and described herein, the upper portion  540 ′ depicted in  FIG. 11E  can include one or more other layers (e.g., quilt or comfort layer  580 ′) positioned above and/or below the fluid distribution member  570 ′. 
     According to other arrangements, a climate controlled bed assembly can include a fluid distribution member that comprises one or more internal channels or other conduits through which air or other fluid may be directed. This can help distribute fluids to one or more desired portions of the bed assembly. 
     One embodiment of a climate controlled bed  610 A having such a fluid distribution member  670 A is schematically illustrated in  FIG. 12A . As shown, the fluid distribution member  670 A can include an inlet  678 A that is in fluid communication with one or more channels  674 A, recesses or other areas within the fluid distribution member  670 A through which fluids may pass. In the depicted arrangement, the fluid distribution member  670 A comprises a plurality of openings  675 A that are in fluid communication with the internal channels  674 A. 
     As a result of such a configuration, air or other fluids delivered through the inlet  678 A and the channels  674 A can be distributed toward the top of the bed (e.g., through a quilt or comfort layer  680 A, other layers or portions of a mattress, etc.). The quantity, shape, size, location, spacing and other details of the inlet  678 A, channels  674 A, openings  675 A and/or any other portion of the fluid distribution member  670 A can vary, as desired or required by a particular application or use. In addition, as discussed herein with reference to the embodiment of  FIG. 12B , a spacer (e.g., a spacer fabric) or other generally flow permeable material can be positioned within one or more locations of the channels  674 A and/or other portion of the fluid distribution member  670 A. Further, although not illustrated herein, an insert, liner, film or other material can be positioned along the channels  674 A or any other portion of the fluid distribution member  670 A. Such inserts can help reduce or prevent fluid losses across the main portion  672 A of the fluid distribution member  670 A. In addition, such members or components can help to structurally reinforce the internal channels and other passageways of the fluid distribution member  670 A, especially when the bed  610 A is being used. Thus, the size and shape of the passageways can be generally maintained to allow air or other fluids to pass therethrough. 
     With reference to  FIG. 12B , the fluid distribution member  670 B can include a fluid inlet  678 B and one or more recessed areas  674 B. As shown, a spacer  676 B (e.g., a spacer fabric, other air permeable material or member, etc.) can be partially or completely positioned within the recessed area  674 B. The spacer  676 B can help to structurally reinforce the recessed area  674 B. In addition, the spacer  676 B can help ensure that air or other fluids are more evenly distributed to one or more desired portions of the fluid distribution member  670 B. As discussed with reference to other embodiments herein, the recessed area  674 B or other portion of the fluid distribution member  670 B can include an insert, liner, film or other member. Air or other fluid entering the inlet  678 B can be distributed (e.g., vertically, laterally, etc.) through the spacer  676 B. Once it exits through the top of the fluid distribution member  670 B, the air or other fluid can be directed toward the top of the bed assembly  610 B through one or more layers or members (e.g., a comfort layer  680 B). 
       FIG. 12C  illustrates an exploded cross-sectional view of another embodiment of an upper portion  640 C for a climate controlled bed  610 C. As shown, the upper portion  640 C can include a core  660 C having one or more internal passageways  652 C. In the depicted arrangement, the core  660 C comprises only a single passageway  652 C. However, it will be appreciated, that the core may include two, three or more passageways  652 C, as desired or required by a particular application. The upper portion  640 C can further include a fluid distribution member  670 C and one or more other layers  680 C (e.g., comfort layer) positioned on top of the core  660 C. 
     With continued reference to  FIG. 12C , the fluid distribution member  670 C can include a spacer  674 C and/or other air-permeable portion that is configured to more evenly distribute air or other fluid throughout the member  670 C. In some embodiments, the spacer  674 C (e.g., spacer fabric or other material) or other distribution portion is at least partially surrounded by an air-impermeable or substantially air-impermeable layer  672 C or member. The air impermeable layer  672 C can comprise a woven fabric, another type of fabric, a film, a laminate, a bag, other enclosure and/or the like. 
     In  FIG. 12C , two openings  676 C in the air impermeable layer  672 C extend generally along the top surface of the fluid distribution member  670 C. Thus, as shown, air or other fluid entering the fluid distribution member  670 C (e.g., through one or more bottom inlets  678 C) can be distributed within the spacer  674 C or other distribution portion. Air or other fluid can exit the interior of the fluid distribution member  670 C toward one or more top layers (e.g., a quilt or comfort layer  680 C, additional fluid distribution members, other layers or members, etc.) through one or more openings  676 C of the air impermeable layer  672 C. Alternatively, as discussed with reference to  FIG. 11E , air or other fluid can be delivered to the fluid distribution member  670 C through one or more external passageways (not shown in  FIG. 12C ), either in lieu of or in addition to an internal passageway  652 C. 
       FIG. 13A  illustrates an embodiment of a climate controlled bed assembly  710 A that includes a top member  790 A that is adapted to be positioned on top of a core  760 A. According to certain arrangements, the top member  790 A comprises a fluid distribution portion  792 A (e.g., a spacer, spacer fabric or other material, etc.), a bottom interface layer  796 A and a top comfort layer  794 A. The bottom interface layer  796 A can comprise foam or another generally cushioned material that is configured to enhance the comfort level of an occupant. 
     In some embodiments, the various layers and/or components of the top member  790 A are configured to be joined together as a unitary structure. For example, the fluid distribution portion  792 A, the bottom interface layer  796 A and the top comfort layer  794 A can be secured to each other using adhesives, stitching, staples, other fasteners and/or any other device or method. As a result, the top member  790 A can be collectively attached to a core  760 A to facilitate assembly of the upper portion  740 A. In some arrangements, the top member  790 A is configured to be fluid communication with one or more passageways  752 A of the core  760 A when the top member  790 A is secured to the core  760 A. 
     In other arrangements, the top member  790 A includes additional or fewer layers or portions, as desired or required. For example, the top member  790 A can comprise one or more additional top layers (e.g., comfort layers). Alternatively, the top member  790 A may not include the bottom interface layer  796 A, so that the fluid distribution portion  792 A (e.g., spacer or other material) directly contacts a top surface of the core  760 A. 
     It will be appreciated that in any of the embodiments disclosed herein, including those illustrated in  FIGS. 1A-35 , one, some or all of the various layers or members of the lower portion (e.g., frame, support structure, covering material, etc.) and/or the upper portion (e.g., core, fluid distribution member or portion, comfort layers, interface layers, etc.) can be attached to each other using adhesives, stitching, staples, other fasteners, etc. Consequently, each of the upper portion and the lower portion can be provided as a single member or two or more separate members. For example, in some arrangements, a top member  790 A having a unitary structure, such as the one discussed herein with reference to  FIG. 13A , may be provided to a buyer, assembler or other party who may subsequently secure it to a core  760 A or other portion of the bed assembly  710 A. In other embodiments, a complete or substantially complete upper portion (e.g., core, fluid distribution member, comfort layer, etc.) can be provided as a single structure for incorporation into a bed assembly. Alternatively, the various layers, members or portions can be provided to others as separate items that will be later incorporated into a climate controlled bed assembly. 
     As illustrated in  FIG. 13B , a climate controlled bed assembly  710 B can include one or more passageways  752 B that are positioned at or near the edge of the interior of the core  760 B. Air or other fluid can be delivered from one or more fluid modules  100  toward the top of the bed  710 B (e.g., the fluid distribution member  770 B, the comfort layer  780 B, etc.) through such a passageway  752 B. In other embodiments, one or more fluid passageways  753 B can be positioned along the outside of the core  760 B and/or other portions of the bed  710 B. Under such a configuration, the need for internal openings through the core  760 B can be advantageously eliminated. 
     In any of the embodiments of a climate controlled bed disclosed herein, including those illustrated and discussed with respect to  FIGS. 1A-35 , the upper portion and/or the lower portion can comprise one or more covering layers or materials. As discussed, the core, the fluid distribution members and the comfort layers can be secured to each other using adhesives, stitching, fasteners and/or other connection method or device. Further, some or all of these components or portions can be selectively wrapped by one or more layers of fabric, bags or other enclosures, other covering material and/or the like. 
     For additional details regarding climate controlled bed assemblies, refer to U.S. patent application Ser. No. 11/872,657, filed Oct. 15, 2007 and published as U.S. Publication No. 2008/0148481, the entirety of which is hereby incorporated by reference herein. One or more of the components, features and/or advantages of the embodiments discussed and/or illustrated herein can be applied to any of the specific embodiments disclosed in U.S. patent application Ser. No. 11/872,657, and vice versa. 
       FIG. 14  illustrates a partial cross-sectional view of another embodiment of a climate control bed assembly  10 ′ having an upper portion  40 ′ (e.g., mattress) and a lower portion  20 ′ (e.g., foundation, box spring, etc.). As shown, the upper portion  40 ′ comprises a quilt or comfort layer  80 ′ and a fluid distribution member  70 ′ positioned above a core  60 ′ (e.g., foam, other filler material, springs, etc.). As discussed herein with reference to other embodiments, the core  60 ′ can include one or more internal passageways  52 ′ that generally extend from the bottom of the upper portion  40 ′ to the fluid distribution member  70 ′ (e.g., spacer fabric) situated on top of the core  60 ′. In certain embodiments, as illustrated in  FIG. 14 , an insert  54 ′ (e.g., bellowed conduit) is positioned within a passageway  52 ′ to help ensure that fluid entering the upper portion  40 ′ does not inadvertently leak or escape prior to entering the fluid distribution member  70 ′ or other layer or region of the mattress  40 ′ (e.g., through the walls of the passageways  52 ′, the interface between the upper and lower portions  40 ′,  20 ′, etc.). 
     With continued reference to  FIG. 14 , once air or other fluid enters the fluid distribution member  70 ′, it may be distributed (e.g., laterally) so that it more evenly flows throughout a portion of the fluid distribution member  70 ′. In order to enhance this fluid distribution effect, a flow diversion member or diverter  74 ′ can be positioned generally above the exit of each internal passageway  52 ′ of the core  60 ′. As illustrated schematically in  FIG. 14 , the diverters  74 ′ can be shaped, sized, positioned and otherwise configured to divert air or fluid laterally throughout at least a portion of the fluid distribution member  70 ′. Consequently, the use of diverters  74 ′ can result in a more even cooling, heating and/or ventilation effect along the top surface of a climate control bed  10 ′. 
     According to certain embodiments, flow diverters  74 ′ comprise air-impermeable or partially air-permeable members that are generally positioned between the fluid distribution member  70 ′ and the quilt or comfort layer  80 ′ positioned above it. Thus, a diverter  74 ′ can comprise a piece of fabric, liner, rigid, semi-rigid or flexible materials and/or the like. In such arrangements, the flow diversion members  74 ′ are relatively small in size and are only intermittently positioned over the flow distribution member  70 ′. However, in other embodiments, a bed can include one or more flow diversion members that extend over most or all of the surface area of the flow distribution member  70 ′. For example, in one arrangement, the diverter comprises a layer or member (e.g., a comfort layer,  80 ′, a separate comfort layer or other type of layer having a plurality of fluid openings, etc.) that is generally positioned above the fluid distribution member  70 ′. 
     With continued reference to  FIG. 14 , in order to help prevent air or other fluid from escaping through the side of the bed  10 ′, the fluid distribution member  70 ′ can include a base or frame  72 ′ along its edges. Alternatively, as discussed in greater detail herein, side losses can be prevented or decreased by using sew seams, stitching, glue beads and/or any other flow blocking member or features. Further, the upper portion  40 ′ can include one or more other layers or members to provide additional comfort and/or other benefits to a user. For example, an additional quilt or comfort layer (not shown in  FIG. 14 ) can be positioned below the fluid distribution member  70 ′ either as a separate layer or incorporated as part of the core  60 ′. 
     As illustrated in  FIG. 14 , one or more intermediate members  37 ′ can be positioned generally between the upper and lower portions of an environmentally-controlled bed assembly. For example, an intermediate member  37 ′ can comprise a felt scrim having a central opening. In some arrangements, the felt scrim  37 ′ is approximately 2 mm thick and 155 mm (6.1 inches) in diameter. In other embodiments, the felt scrim or other intermediate member  37 ′ includes a different shape, such as, for example, square, diamond, other rectangular, other polygonal, oval, irregular and/or the like. As shown, the intermediate member  37 ′ can include a central opening, which in some embodiments, is shaped and sized to generally match or otherwise correspond to the opening size of the adjacent components of the climate control bed (e.g., the flange  38 ′, the interconnecting conduit  39 ′, the insert  54 ′ positioned within the passageway  52 ′, etc.). In other embodiments, the shape, size and other characteristics of the intermediate member  37 ′ can vary, as desired or required. The intermediate member  37 ′ can be configured to secure to an adjacent surface of the upper portion and/or the lower portion of the bed assembly using adhesives (e.g., an adhesive strip), fasteners and/or any other connection device or method. 
     Regardless of their exact shape, size and configuration, such scnms or other intermediate members  37 ′ can offer one or more benefits and advantages to an environmentally-controlled bed assembly. For example, an intermediate member  37 ′ can be configured to cover the flanged end  55 ′ of the insert  54 ′ and secure it to the adjacent lower surface of the upper portion  40 ′. Thus, the intermediate member can help ensure that the insert  54 ′ properly extends between the opposing ends of the passageway  52 ′, thereby preventing undesirable pull-through of the insert  54 ′ into the passageway  52 ′. In addition, such a scrim or other intermediate member  37 ′ can help reduce the likelihood of leaks as conditioned and/or unconditioned fluids are conveyed from a fluid module toward an occupant. For instance, the intermediate member  37 ′ can be configured to prevent or substantially prevent conditioned air from retrograde flow (e.g., through the insert toward the interface between the upper and lower portions of the bed assembly, through the passageways, etc.). 
     With continued reference to the cross-sectional view of  FIG. 14 , the lower portion  20 ′ (e.g., foundation) can include a backer board  110  or other panel member to which one or more components (e.g., fluid module  100 ′, power supply  112 ′, control unit  114 ′, humidity sensor  116 ′, other types of sensors, etc.) of the climate control bed assembly  10 ′ can be secured. In  FIG. 14 , the backer board  110  is incorporated into a lower end of the foundation  20 ′ and extends the entire length of the bed  10 ′. However, in other arrangements, the backer board  110  can have a different location or orientation within the foundation or other lower portion  20 ′. Further, the backer board  110  can be configured to extend only partially across an area of the lower portion  20 ′ and the bed  10 ′. 
     The backer board  110  can have a generally rigid, semi-rigid and/or flexible construction, as desired or required by a particular bed. For example, in certain arrangements, the backer board  110  comprises plastic and/or other rigid or semi-rigid materials that are configured to form an outer panel or wall along one or more sides of the foundation  20 ′. However, in other embodiments, the backer board  110  is positioned within an interior region of the foundation  20 ′. In such arrangements, the lower portion  20 ′ can include a separate panel (e.g., comprising plastic, wood or other rigid, semi-rigid or flexible materials) or covering member (e.g., fabric) in order to generally shield an interior space of the lower portion. 
     Regardless of its exact shape, size, location and orientation within a portion of a bed and/or other of its characteristics, a backer board  110  can offer certain advantages. For example, the construction, installation and assembly of one or more components (e.g., fluid modules, control modules or units, power supplies, sensors, etc.) of a climate control system can be facilitated, as such components can be secured to the backer board  110  prior to incorporating the backer board  110  into the foundation  20 ′. Relatedly, a separate backer board  110  configuration can assist in the storage, shipping and transportation of a climate controlled bed assembly. Further, in embodiments where the backer board  110  can be selectively removed from the foundation or other portion of the bed, the repair and maintenance of the bed can be facilitated. For instance, when the climate control system is in need of service, the backer board  110  can be removed and the necessary repairs, servicing and/or other adjustments can be conveniently performed away from the location of the bed assembly (e.g., in a remote service facility, in another room, etc.). As noted herein, the backer board  110  can be positioned along the bottom, top, side, interior and/or any other portion of the foundation  20 ′ or lower portion. In other embodiments, the backer board  110  can be designed to be directly incorporated into a mattress or another type of upper portion  40 ′ of a climate controlled bed. For example, the backer board can be adapted to generally form at least a portion of the lower surface of the mattress. 
     The backer board  110  can include one or more openings and/or other features adapted to accommodate the various components secured thereto. In the embodiment depicted in  FIG. 14 , for example, the backer board  110  comprises openings  134  at the inlet of each fluid module  100 ′. In addition, the backer board  110  can include openings  135 A,  135 B through which cables and/or other hardwired connections may pass. Further, although not illustrated herein, the backer board  110  can be advantageously configured to better accommodate the various components that are attached thereto. For example, the backer board  110  can comprise recesses (e.g., that are sized and shaped to receive a fluid module, power supply, etc.), tabs, slots, flanges, threaded connections and other features configured to more easily accommodate screws, fasteners and/or other connection devices and/or the like. 
     With continued reference to  FIG. 14 , the foundation  20 ′ can include one or more thermal insulation baffles  23 ′ or fluid dams that are intended to generally separate the interior of the foundation  20 ′ into two or more distinct regions. In the depicted arrangement, the foundation  20 ′ comprises a total of two fluid modules  100 ′ that are adapted to selectively provide thermally conditioned and/or ambient air through corresponding passageways  52 ′ of the mattress or upper portion  40 ′. When the bed is operating under a “cooling” mode, the main outlet conduits  106 ′ downstream of the respective fluid modules  100 ′ convey relatively cold air, while the waste outlet conduits  108 ′ convey relatively hot air. As shown in  FIG. 14 , the main outlet conduits  106 ′ remain within a main zone M, an area generally defined between the insulation baffles  23 ′, before exiting the top of the foundation  20 ′. 
     Further, the fluid conveyed by the waste outlet conduits  108 ′ is directed across the insulation baffles  23 ′ and into separate waste zones W 1 , W 2  located on either side of the main zone M. In other embodiments, a foundation or lower portion  20 ′ can include more or fewer main zones M and/or waste zones W 1 , W 2 , as desired or required. For example, in one arrangement, a lower portion includes only one main zone and only one waste zone. Thus, the main fluid outlet and/or the waste fluid outlet downstream of the fluid modules can be directed into a single zone. 
     As a result of the thermal baffles  23 ′ or dams, the temperature within each zone M, W 1 , W 2  of the foundation  20 ′ can vary during operation of the bed&#39;s climate control system. For example, as discussed above, when cold air is being supplied to the upper portion  40 ′, the main portion is relatively cold and the waste portions W 1 , W 2  are relatively hot. Since the waste fluid is directed away from the main outlets  106 ′ (e.g., toward the waste zones W 1 , W 2 ), the heat of the waste fluid is generally not permitted to affect the temperature of the relatively cold main fluid. Likewise, under such a configuration, when the bed is operating under a “hot” mode, the amount of heat that is lost from the main outlet conduits  106 ′ and the main zone M can be advantageously reduced, as the relatively cold air being conveyed through the waste outlet conduits  108 ′ is generally not permitted to draw heat away from the main outlet conduits  106 ′ and the main zone M. Accordingly, the efficiency of the thermal conditioning process occurring within the bed assembly can be advantageously improved. 
     In addition, it may be desirable to maintain separate “cold” and “hot” zones M, W 1 , W 2  within the foundation in order to provide a desired operating environment for one or more components of the bed&#39;s climate control system. For instance, depending on the anticipated mode or modes of operation for a particular bed assembly, the fluid modules  100 ′, power supply  112 ′, control unit  114 ′, temperature sensors, humidity sensors  116 ′, other types of sensors and/or the like may operate more efficiently or reliably when located in an environment having a specific ambient temperature. Relatedly, the useful life of such components can be increased if they are located within an environment having a particular temperature range. 
     In order to provide additional thermal shielding between the main and waste streams, the various fluid conduits  103 ′,  106 ′,  108 ′ located within the foundation  20 ′ can comprise one or more insulating materials  105 ′,  107 ′,  109 ′ (e.g., foam or fiberglass insulation, other thermal insulation, etc.). For example, as illustrated in  FIG. 14 , the conduits  103 ′ that place the blowers  102 ′ or other fluid transfer devices in fluid communication with the corresponding thermoelectric devices  104 ′ can include thermal insulation  105 ′. Further, one or more of the outlet conduits  106 ′,  108 ′ downstream of the fluid modules  100 ′ can also be thermally insulated, as desired or required. 
       FIGS. 15A-15C  illustrate various views of a lower portion  120  (e.g., foundation) of a climate controlled bed configured to maintain one, two, three or more thermally distinct zones. In addition, according to some arrangements, as discussed in greater detail herein, a foundation  120  comprises a thermal curtain or bed skirt  140  in order to help preserve such distinct thermal zones in the space immediately below the main portion  130  of the foundation  120 . 
     With specific reference to  FIG. 15A , a foundation  120  (or other lower portion) of a climate controlled bed assembly can comprise a main zone M or region in which the various components (e.g., fluid modules, power supply, control units, sensors, etc.) of the climate control system can be housed. As discussed with reference to  FIG. 14 , one or more panels, walls or other members that help to define the main zone M can include backer board. For example, in the depicted embodiment, the main lower panel  132  comprises a backer board, which is configured to receive one or more components of the climate control system along an interior surface. As shown, the backer board panel  132  can include openings  134  that are sized, shaped and configured to generally correspond to inlet of the fluid modules (e.g., fluid transfer devices) positioned within an interior of the foundation&#39;s main zone M. In some arrangements, as illustrated in  FIGS. 15A and 15B , the foundation  120  also includes side panels  123 , which, together with the main lower panel  132 , help define the main zone M. The side panels  123  can comprise a rigid, semi-rigid and/or flexible member that is configured to physically and/or thermally isolate the main zone M from each of the adjacent waste zones W 1 , W 2 . For example, in some embodiments, such side panels  123  comprise one or more materials that have favorable fluid blocking and/or thermal insulation properties. 
     As discussed herein with reference to  FIG. 14 , the waste air exiting the fluid modules can be directed out of the main zone M of the foundation into adjacent waste zones W 1 , W 2  using one or more waste outlet conduits. In the embodiment of  FIGS. 15A-15C , the waste outlet conduits  135  direct waste fluid into interior regions  136  of the foundation&#39;s waste zones W 1 , W 2 . In some arrangements, such interior regions  136  are defined by one or more panels and/or covering materials  137  (e.g., fabric layers, sheets, liners, etc.). For instance, in  FIG. 15A , a covering material can include an air-permeable or generally air-permeable fabric. In other embodiments, the foundation  120  comprises one or more fluid outlets (not shown) through which air or other fluids can freely enter or exit the main zone M and/or the waste zones W 1 , W 2 . 
     In order to extend the thermal isolation zones below the structural portion  130  of the foundation  120 , the foundation can include a thermal bed skirt  140  or curtain. One embodiment of a thermal bed skirt  140  is illustrated in  FIGS. 15B and 15C . As shown, the skirt  140  can include a plurality of exterior and interior sections  142 ,  146 ,  148  that help divide the interior space of the skirt  140  into separate regions. The thermal skirt  140  or curtain can be configured to provide at least a partial barrier against fluid flow and/or heat transfer. 
     In the depicted embodiment, the separate regions generally align with the zones M, W 1 , W 2  of the foundation&#39;s structural upper portion  130 . For example, the interior sections  148  of the thermal skirt  140  or curtain are located directly or nearly directly below the side panels of the main zone M when the skirt  140  is properly secured to the foundation  120 . Accordingly, ambient air can be drawn into the fluid modules (not shown), through recesses  144 , notches or other cutouts along the bottom of the skirt  140  and the inlets  134  in the main lower panel  132 . In certain arrangements, the interior sections  148  of the thermal skirt  140  are configured to prevent or reduce the likelihood of waste fluid (e.g., present within, below or near each of the waste zones W 1 , W 2 ) from entering the main zone M (e.g., toward the inlets of the fluid modules). The thermal skirt  140  can be secured to adjacent portions of the foundation  120  using one or more connection methods or devices, such as, for example, stitching, adhesives, clips, hooks, staples and/or other fasteners and/or the like. 
       FIGS. 16A and 16B  illustrate one embodiment of a mattress  150  (e.g., upper portion) configured for use with an environmentally-controlled bed assembly. As shown, the mattress  150  can include a bottom layer  152 , a top fluid distribution layer  156  and a middle layer  154  positioned therebetween. According to one arrangement, the bottom layer  152  comprises foam, spacer fabric, a quilt or comfort layer, other filler materials, springs, air chambers and/or any other material or component, as desired or required for a particular design. Further, the middle layer  154  can include a sheet, film, fabric or any other material that is flexible and generally fluid impermeable. The middle layer  154  can be adapted to be cleanable (e.g., capable of being wiped down or otherwise sterilized) and reusable. In certain arrangements, the middle layer  154  is a sheet or layer comprising vinyl, other polymeric materials and/or any other synthetic or natural materials. Moreover, the upper layer  156  can include a spacer fabric, another fluid distribution member and/or other materials that are at least partially porous or air permeable. Alternatively, the upper layer  156  can be configured to permit fluids to be distributed therein and pass therethrough (e.g., using internal channels, pores, etc.), despite comprising one or more generally fluid impermeable materials. 
     According to certain embodiments, the upper layer  156  (e.g., spacer fabric) is adapted to be selectively separated and removed from the adjacent layers and portions of the mattress  150 . Consequently, the upper layer  156  can be washed, and as discussed in greater detail herein, subsequently re-attached to the mattress  150 . Alternatively, the upper layer  156  can be removed and replaced with a new upper layer  156 . The middle layer  154  (e.g., vinyl sheet) can be advantageously cleaned (e.g., wiped down) or otherwise treated whenever the upper layer  156  is removed from the mattress  150 . Thus, the middle layer  156  and the bottom layer  152  of the mattress can be reused multiple times, as they are unlikely to come in contact with the bed&#39;s occupant or any contaminants to which the bed may be exposed. Such a configuration can be particularly useful for medical beds and other applications where frequent cleaning of the bed is desired or required and/or where the bed is likely to cycle through multiple users over a specific time period. 
     In certain arrangements, the bottom and middle layers  152 ,  154  of the mattress  150  are secured to each other using one or more connection devices or methods, such as, for example, stitching, adhesives, clips, other fasteners and/or the like. Similarly, the fluid inserts  158  (e.g., bellowed ducts) that pass at least partially through the depth of the mattress  150  can be attached to the middle layer  154  (e.g., vinyl layer) using one or more connection methods or devices. As noted herein, according to some arrangements, the upper layer  156  (e.g., spacer fabric) is releasably attached to the adjacent layers or portions of the mattress  150  using one or more removable connections. For example, in  FIGS. 16A and 16B , the upper layer  156  comprises a plurality of relatively narrow slits  157  or other openings along or near one or more of its outer edges. In the depicted embodiment, the upper layer  156  includes a total of four slits  157 , one along each of its sides. However, the quantity, size, shape, location, spacing and/or other details regarding the slits  157  can vary, as desired or required. 
     With continued reference to  FIGS. 16A and 16B , the slits  157  or other openings can be sized, shaped and otherwise adapted to receive a loose end of the middle layer  154  (e.g., sheet or film) therethrough. Thus, in order to secure an upper layer  156  (e.g., spacer fabric) to the mattress  150 , one or more of the middle layer&#39;s free ends can be passed upwardly through corresponding slits  157  from the bottom of the upper layers  156 . As illustrated in  FIG. 16B , once all the free ends of the middle layer  154  have been properly passed through the corresponding slits  157 , they may be folded (e.g., either toward or away from the center of the mattress) along the top surface of the upper layer  156 . In other embodiments, the mattress  150  includes one or more additional devices or features that help ensure that the upper layer  156  does not separate from or inadvertently move relative to the adjacent portions and layers of the mattress  150  during use. For example, buttons, zippers, snap connections, hook and loop fasteners, other types of fasteners can be used to temporarily secure the upper layer  156  to the mattress  150 . 
     Another embodiment of a mattress or upper portion  170  of a climate controlled bed assembly is illustrated in  FIGS. 17A-17C . As shown, the mattress  170  can include a plurality of layers or portions  172 ,  174 ,  176 . Such portions  172 ,  174 ,  176  can be separate members that are maintained in a desired orientation relative to each other using an outer cover  178  or other enclosure. In certain arrangements, the outer cover  178  comprises one or more zippers and/or other types of releasable attachment devices or features (e.g., buttons, snap connections, hook and loop fasteners, other types of fasteners, etc.) that enable a user to selectively enclose (or release) the layers or portions within an interior space of the cover  178 . 
     With continued reference to  FIGS. 17A-17C , the mattress  170  can include lower and upper portions  172 ,  176  that comprise high performance foam, viscoelastic foam, memory foam, open-cell foam, closed-cell foam, other types of foam, filler materials, other natural or synthetic materials, spring coils, air chambers and/or the like, as desired or required. As shown, the mattress can further include a middle portion  174  that is generally situated between the lower and upper portions  172 ,  176 . According to certain arrangements, the middle portion or layer  174  comprises a fluid distribution member, such as for example, a spacer fabric or any other material or member capable of at least partially distributing fluids therethrough (e.g., an open cell foam, a member having an open lattice design, a member having a porous structure, etc.). Accordingly, air or other fluids entering the middle portion  174  can be laterally distributed before exiting through the upper portion  172 . As discussed herein with reference to other embodiments, a flow diversion member  184  or a diverter can be positioned generally above the middle portion  174  (e.g., in locations at or near the fluid inserts or ducts) to help provide a more even distribution of air or other fluid within the fluid distribution member. 
     As illustrated in  FIGS. 17A and 17C , a fluid insert  180  (e.g., bellowed conduit) can be positioned within an interior of the mattress  170 . In the depicted embodiment, the insert  180  extends from the bottom of the mattress to the lower end of the middle portion  174  (e.g., the spacer fabric or other fluid distribution member). As discussed herein with reference to  FIG. 14 , one or more intermediate members  182  (e.g., a felt insulator, another type of scrim, etc.) can be positioned adjacent the flanged end  181  of the insert  180  to help maintain the insert in a desired orientation (e.g., to prevent the insert from undesirably pulling through the corresponding passageway of the lower portion  172 ), to help reduce the incidence of retrograde fluid flow through one or more undesirable portions or areas of the mattress (e.g., leaks through the lower portion  172 , passageways in which the inserts  180  are routed, etc.) and/or the like. 
     With continued reference to  FIGS. 17A-17C , the bellowed duct  180  or any other insert can advantageously place the middle portion  174  (e.g., spacer fabric, other fluid distribution member, etc.) in fluid communication with a fluid module  100 . In certain arrangements, the fluid module  100  is configured to selectively heat or cool air or other fluids passing therethrough. Alternatively, the fluid module  100  can be adapted to simply transfer ambient air, and thus, need not have the ability to thermally condition fluids. Accordingly, depending on the level of environmental conditioning desired for a particular mattress, the fluid module  100  can comprise one or more components or features, such as, for example, a blower or other fluid transfer device, a thermoelectric device (e.g., Peltier circuit), a convective heater or some other type of thermal conditioning device, temperature, relative humidity and/or other types of sensors and/or the like. As illustrated in  FIG. 17A , in some embodiments, the fluid module  100  is positioned generally underneath the foundation F or other support member (e.g., frame, box spring, etc.). Alternatively, as discussed herein with reference to other arrangements, the fluid module  100  can be positioned above the foundation F (e.g., below the mattress  170 , incorporated into one or more portions of the mattress, etc.). 
     According to certain arrangements, the upper and/or lower portions  176 ,  172  are configured to permit air or other fluids to pass therethrough. For example, these portions can include a porous structure (e.g., open-cell foam). Alternatively, the portions  172 ,  176  can include a plurality of holes, channels or other openings through which fluids may pass. As illustrated in  FIG. 17B , in some arrangements, the upper portion  176  (e.g., porous foam member) and the middle portion (e.g., fluid distribution member) are contained within an interior space of an additional enclosure  177 . In some embodiments, such an enclosure  177  includes a plastic sheet or film, a bag and/or any other member that is adapted to partially or completely surround the upper and middle portions  176 ,  174 . Such a configuration can further ensure that air or other fluid will not undesirably retrograde flow through the lower portion  172  once it has been delivered to the fluid distribution member. The additional enclosure  177  can comprise a porous top surface, so that fluid can exit the upper portion  176 , toward and through the outer cover  178 . 
     In operation, after being delivered by the fluid module  100  to the middle portion  174  (e.g., fluid distribution member), thermally-conditioned (e.g., cooled, heated) or thermally-unconditioned (e.g., ambient) air can pass through the upper portion  176  (e.g., foam with a plurality of fluid openings, other porous member, etc.) of the mattress  170 . From there, the air or other fluid can exit the top surface of the upper portion  176 , through the various layers situated above the upper portion (e.g., an enclosure  177 , an outer cover  178 , etc.), in the general direction of the mattress&#39;s occupant. 
     Such an embodiment can advantageously enable a user to selectively remove one or more portions or members of the mattress  170  for repair, servicing, replacement and/or any other activity or task. In some arrangements, the various portions of the mattress  170  are maintained in a desired relative orientation using a cover or other enclosure that can be opened and closed (e.g., using zippers, buttons, etc.). Further, the mattress, which comprises a relatively simple yet unique design, is relatively inexpensive to manufacture, assemble, store, transport, repair and maintain. 
     In some arrangements, a mattress can include more or fewer (and/or different) portions or layers than depicted in  FIGS. 17A-17C . By way of example, the mattress  170 ′ illustrated in  FIG. 17D  comprises additional portions than the mattress of  FIGS. 17A-17C . Further, in the depicted embodiment, the orientation and general configuration of the different portions also varies. For instance, in  FIG. 17D , the mattress comprises additional layers  190 ′,  192 ′ along its upper region. Moreover, the fluid module  100  is configured to selectively deliver fluid into a spacer fabric or other fluid distribution member  192 ′ that is situated closer to the top of the mattress  170 ′. As with the arrangement of  FIGS. 17A-17C , the mattress  170 ′ can be positioned on a foundation. For other base member. If the fluid module  100  is positioned below the foundation F, an opening can be provided therethrough in order to accommodate the passage of a bellowed duct  180 ′ or other conduit. Alternatively, the fluid module can be placed in fluid communication with the mattress using one or more conduits that are configured to go around (rather than through) the foundation F. With continued reference to  FIG. 17E , a climate controlled mattress  170 , such as those discussed herein with reference to  FIGS. 17A-17D , or equivalents thereof, can be sized, shaped and otherwise adapted to be positioned on a foundation F, box spring and/or any other type of bed frame. In some embodiments, as illustrated in  FIG. 17E , the foundation F can be configured to be selectively reclined or otherwise moved in a desired manner by a user. 
     A climate control assembly according to any of the embodiments disclosed herein, or equivalents thereof, can be constructed, assembled and otherwise configured to include one or more noise abatement or reduction features. Such measures can be directed to reducing air borne noise and/or structure borne noise. 
     For example, in certain embodiments, one or more noise muffling devices are positioned on or near a fluid intake (e.g., an inlet opening of a foundation, a fluid module inlet, etc.). Alternatively, one or more of the fluid intakes associated with a climate controlled bed assembly can be designed to be remote to the location of the bed. For instance, an ambient air intake can be positioned in a different room, in another interior location of a building, near a window or other opening, along an exterior portion of a building that houses the bed and/or the like. Accordingly, if an inlet is located sufficiently far away from the bed, the impact of any air borne noise to an occupant can be advantageously mitigated. In other arrangements, a windsock, vanes, grates or other flow conditioning members, acoustic insulating materials and/or other soundproofing devices or methods can be used within, on or near the inlets, outlets, fluid conduits and/or any other hydraulic components of a bed&#39;s climate control system. Regardless of the specific noise reduction techniques utilized, the level of white noise and/or other air borne noise caused by the movements of air through the various components and portions of a bed can be reduced. 
     In addition, a climate controlled bed assembly can include one or more devices and/or methods that help reduce structure borne noise. According to certain embodiments, vibration dampening devices and components can be used at various locations of the bed. For example, rubber grommets can be used at or near the connections of the fluid modules (e.g., blowers, fluid transfer devices, etc.) and/or any other component of the climate control system that is configured to rotate or otherwise move with a particular frequency. Such devices can help reduce vibration, and thus, the overall structure borne noise level generated by an environmentally-conditioned bed during use. As noted above, such noise reduction measures can be incorporated into any of the bed embodiments disclosed herein, or equivalents thereof. 
       FIG. 18A  illustrates one embodiment of a climate controlled bed  810  comprising one or more of the components or features disclosed herein. As shown, the bed  810  includes an upper portion  840  generally positioned on top of a lower portion  820 . The lower portion  820  can comprise a control panel  850  along one of its outer surfaces. For example, in the arrangement illustrated in  FIG. 18A , the panel  850  includes an ON/OFF switch  852 , a power port  854  (e.g., AC port adapted to receive a power cord  860 ) and one or more ports  856 ,  858  for connecting remote control devices  862 ,  864  or similar controllers. 
     The control panel  850  and its various features can be operatively connected to the fluid modules, controllers or other control units and/or any other electrical components of the climate controlled bed  810 . Thus, a user can control the operation of the bed  810  using a remote control device  862 ,  864  and/or any switches, knobs and/or other selectors positioned on the control panel  850  or any other portion of the bed  810 . As shown, the power cord  860 , the remote control devices  862 ,  864  or the like can be removably attached to corresponding slots or other connection sites on the control panel  850 . This can permit a user to disconnect some or all of the components from the panel  850  when the climate control features of the bed are not desired or when the bed is being serviced, repaired, moved or repositioned. 
     For any of the embodiments disclosed herein, or equivalents thereof, the operation of the bed assembly can be controlled using one or more wireless control devices (e.g., remote controls or other handheld devices). In some arrangements, for example, the control devices can be configured to communicate with a main processor, control unit, one or more fluid modules, timers, sensors (e.g., temperature sensors, humidity sensors, etc.) and/or any other components using infrared, radio frequency (RF) and/or any other wireless methods or technologies. 
       FIG. 18B  illustrates another embodiment of a climate controlled bed assembly  910  that comprises two separate lower portions  920 A,  920 B. Each lower portion  920 A,  920 B can include one or more fluid modules (not shown), controllers and/or other components of the climate control system. The upper portion  940  can be configured to rest on top of both lower portions  920 A,  920 B. As discussed herein with respect to other embodiments, the upper portion  940  can include a core, a fluid distribution member, a comfort layer and/or any other layer or component. In the depicted arrangements, the lower and upper portions  920 A,  920 B,  940  are configured to permit ambient and/or thermally conditioned air from the fluid modules to be conveyed toward the top of the bed  910  through one or more passageways, fluid distribution members, comfort layers and/or the like. 
     With continued reference to  FIG. 18B , each lower portion  920 A,  920 B can comprise a control panel  950 A,  950 B. In some embodiments, the control panels  950 A,  950 B can include an ON/OFF switch  952 , slots or other connection sites  954 ,  956 ,  958  for removably connecting power cords  960 A,  960 B, remote control devices  962 ,  964  and/or any other component. 
     Another embodiment of a climate control bed  1010  is illustrated in  FIG. 18C . As with the arrangement of  FIG. 18B , the depicted bed  1010  includes two separate lower portions  1020 A,  1020 B and a single upper portion  1040 . Each of the lower portions  1020 A,  1020 B comprises a control panel  1050 A,  1050 B generally positioned along a side surface. In some embodiments, the panels  1050 A,  1050 B are different from each other. For example, one of the panels  1050 A can include an ON/OFF switch  1052 , slots or other connection sites  1054 ,  1056 ,  1058  for removably docking one or more power cords  1060 , remote control devices  1062 ,  1064  and/or the like. In addition, the control panel  1050 A can include a port  1059 A or other connection site configured to receive a cable  1061  or other connector that is in power and/or data communication with a corresponding port  1059 B on the control panel  1050 B of the second lower portion  1020 B. Accordingly, any fluid modules, controllers and/or any other components positioned within or associated with the second lower portion  1020 B can be advantageously controlled using the control panel  1050 A positioned on the first lower portion  1020 A. This can simplify the control panel  1050 B of the second lower portion  1020 B, by requiring fewer features or components, such as, for example, control devices (e.g., ON/OFF switch  1052 ), connection sites (e.g., power cord ports  1054 , remote control device ports  1056 ,  1058 , etc.) and/or the like. 
       FIG. 18D  illustrates another embodiment of a climate controlled bed assembly  1110  having two separate lower portions  1120 A,  1120 B and a single upper portion  1140 . For simplicity, the various components and other features of the climate control system (e.g., inlets, fittings or passageways within the upper portion  1140  and the lower portions  1120 A,  1120 B, etc.) are not shown. In  FIG. 18D , only one of the lower portions  1120 B comprises a control panel  1150 . Thus, as shown, the electrical components of the lower portions  1120 A,  1120 B can be operatively connected using one or more interconnecting cables  1172 ,  1174 . In the depicted arrangement, the interconnecting cables  1172 ,  1174  are configured to connect to each other along the interior adjacent surfaces of the lower portions  1120 A,  1120 B, such that the cables  1172 ,  1174  remain hidden when the bed  1110  has been assembled. In other arrangements, however, the interconnecting cables  1172 ,  1174  or other devices can be positioned at any location of the lower portions  1120 A,  1120 B and/or another area of the bed  1110 . 
     Another arrangement of a climate controlled bed assembly  1210  is illustrated in  FIG. 18E . As shown, each of the lower portions  1220 A,  1220 B includes a control panel  1250 A,  1250 B. In some embodiments, each control panel  1250 A,  1250 B comprises a single port  1252  or other connection site configured to receive a cable. However, a control panel can include one or more additional ports or other connection sites, as desired or required. Interconnecting cables  1254 A,  1254 B that are connected to ports  1252  of the control panels  1250 A,  1250 B can be fed into an external control module  1270 . 
     With continued reference to  FIG. 18E , the external control module  1270  can include ports  1282  that are adapted to receive the interconnecting cables  1254 A,  1254 B. In addition, the external control module  1270  can include one or more switches or other control devices (e.g., an ON/OFF switch  1272 ), other ports or connection sites (e.g., power cord ports  1274 , remote control device ports  1276 ,  1278 , etc.) and/or the like. Thus, the external control module  1270  can be used to supply power to the various electrical components (e.g., fluid modules, control units, etc.) of the bed assembly  1210 . In addition, the external control module  1270  can provide a single device through which such components may be operatively controlled. In some embodiments, the external control module  1270  can be configured to be placed underneath the bed assembly  1210  or at another discrete location when the bed  1210  is in use. 
       FIGS. 19A through 23  illustrate various embodiments of enclosures configured to receive a control panel for a climate controlled bed. The depicted enclosures are generally positioned along the lower portions of the respective bed assemblies. However, such enclosures can be positioned within or near another part of the bed. 
     With reference to  FIGS. 19A-19C , the bed  1310  comprises an enclosure  1325  that generally abuts an exterior surface (e.g., rear, front, side, etc.) of the lower portion  1320  when secured therein. As shown, the various structural and other components of the enclosure  1325  can be sized, shaped and otherwise configured to receive a control panel  1350 . The enclosure  1325  can be secured to one or more regions of the lower portion  1320  (e.g., a frame member, the frame structure, etc.). In addition, the control panel  1350  can be attached to the enclosure using one or more screws, other fasteners and/or the like. 
     As illustrated in  FIGS. 20A-20C , an enclosure  1425  can include more or fewer structural or non-structural members. In addition, the enclosure  1425  can comprise different types of fasteners (e.g., screws, tabs, etc.) and/or other members, as desired or required. In some embodiments, the enclosure includes rigid, semi-rigid and/or non-rigid (e.g., flexible) members that comprise wood, metal (e.g., steel), composites, thermoplastics, other synthetic materials, fabrics and/or the like. 
     In the embodiment depicted in  FIGS. 21A-21C , the enclosure  1525  includes a frame  1526  generally positioned along an exterior of the lower portion  1520  of the bed assembly  1510 . The frame  1526  can be attached to the lower portion  1520  using one or more connection methods or devices. As shown, the enclosure  1525  can further include a cage  1527  or the like. With reference to  FIG. 21C , the cage  1527  can be attached to both the frame  1526  and one or more areas of the lower portion  1520  of the bed  1510 . Once positioned within an interior of the enclosure  1525 , the control panel  1550  can be attached to the frame  1526  and/or the cage  1527  of the enclosure  1525  using one or more tabs  1529 , other fasteners, welds and/or any other connection device or method. 
     In some embodiments, as illustrated in  FIGS. 22A-22D , a control panel  1625  can be secured to a lower portion  1620  or other portion of a bed using a simpler design. For example, the enclosure  1625  depicted in  FIG. 22A  includes a smaller frame  1626  and a reinforcing structure  1627  adjacent to the frame  1626 . Thus, an enclosure may not extend very far, if at all, into an interior of a lower portion  1620  or other portion of a climate controlled bed assembly. In the illustrated arrangement, a fabric  1635  or one or more other protective films or layers can be positioned between the enclosure  1625  and the exterior of the lower portion  1620 . Thus, such a fabric  1635  can hide the enclosure  1625  and serve as an interface between the enclosure  1625  and the control panel  1650  that is secure thereto. 
     One or more additional members or devices can be used to secure a control panel within an enclosure or other area of the bed assembly. For example, with reference to  FIG. 23 , a faceplate  1790  can be positioned along the outside of the control panel  1750 . In some embodiments, such a faceplate  1790  or other member can help secure the control panel  1750  to the corresponding enclosure. It will be appreciated that in any of the embodiments of the climate controlled bed assemblies disclosed herein, including those illustrated in  FIGS. 1A-28B , the control panels can be configured to be selectively removable from the corresponding enclosure or other area of the bed. This can facilitate the manufacture, assembly, transport, maintenance, repair and/or any other activities associated with providing and operating a climate controlled bed. 
     In addition, in embodiments that include control panels with switches, other control devices, ports and/or the like, such as, for example, those illustrated in FIGS.  14 - 23 , users can conveniently configure a climate controlled bed assembly for use in just a few steps. For example, before the climate control features of such a bed assembly can be activated, a user may need to connect a power cable, a remote control device, an interconnecting cable and/or any other device to one or more control panels (e.g., along a lower portion of the bed). In some embodiments, the user may also need to select a desired setting or mode of operation using an ON/OFF switch and/or any other control device. 
     In some embodiments, as illustrated in  FIG. 24A , a fluid module  100  (e.g., a blower or other fluid transfer device, a thermoelectric device, etc.) can be positioned (e.g., partially or completely) within a recess area  1890 A or other cavity of the core  1860 A. As a result, the fluid module  100  can be placed in fluid communication with one or more passageways  1852 A of the core  1860 A. In the illustrated arrangement, air or other fluid being transferred by the fluid module  100  (e.g., toward or away from the top of the bed assembly  1810 A) is conveyed within an insert  1854 A that is generally positioned within the recess area  1890 A and/or the passageway  1852 A. As shown, the insert  1854 A can include bellows or other similar features to accommodate movements in the core  1860 A when the bed assembly  1810 A is in use. As with other embodiments discussed herein, air or other fluid can be conveyed from the fluid module  100  to a top surface of the bed assembly  1810 A through one or more fluid distribution members  1870 A (e.g., spacer), comfort layers  1880 A and/or any other layers or members positioned above the core  1860 A. Alternatively, air can be drawn away from a top area of the bed assembly  1810 A. 
     Such a configuration can help eliminate the need for a separate lower portion or other component that houses one or more fluid modules. For example, the climate controlled bed  1810 A illustrated in  FIG. 24A  can be positioned directly on a box spring, the floor or any other surface. The fluid module  100  can be secured to the core  1860 A and/or any other portion of the bed assembly  1810 A using adhesives, fasteners and/or any other attachment device or method. 
     Another embodiment of a core  1860 B being configured to accommodate one or more fluid modules  100  is schematically illustrated in  FIG. 24B . As shown, the fluid modules  100  can be positioned within recess areas  1890 B or other cavities formed along the bottom surface of the core  1860 B. In other embodiments, the fluid modules  100  are positioned along a different surface or within another portion of the core  1860 B. As discussed, such a configuration can help eliminate the need for a separate lower portion or other bed component that is adapted to house the fluid modules  100 . Consequently, the core  1860 B may be positioned on a standard box spring, a floor or any other surface. 
     With continued reference to  FIG. 24B , the core  1860 B can include inlet channels  1892 B through which air or other fluid may be drawn into the inlet of the fluid modules  100 . Likewise, the core  1860 B can comprise outlet channels  1894 B that are configured to remove a volume of air or other fluid away from the bed assembly  1810 B. For example, in embodiments where the fluid module  100  comprises a thermoelectric device, the outlet channels  1894 B can be used to remove the waste air stream (e.g., heated air when cooled air is being delivered to the top of the bed assembly  1810 B, or vice versa) away from the core  1860 B. 
     In some embodiments, the channels  1892 B,  1894 B are lined (e.g., using films, coatings, liners, inserts, etc.) to reduce the likelihood that air will enter the core  1860 B, to structurally reinforce the channels  1892 B,  1894 B and/or for any other purpose. In addition, the inlet channels  1892 B can include one or more filters to ensure that no dust, debris, particulates or other undesirable substances enter the fluid modules. Further, if the bed assembly  1810 B is being operated so that air is being drawn away from occupants positioned thereon, air can be discharged through the inlet channels  1892 B and/or the outlet channels  1894 B. It will be appreciated that the size, shape, quantity, spacing, location, orientation and/or other details about the recesses  1890 B, inlet channels  1892 B and/or outlet channels  1894 B can be varied, as desired or required. 
     As illustrated in  FIGS. 25-30 , a climate-conditioned bed assembly according to any of the embodiments disclosed herein can be placed in fluid communication with the HVAC system of a home or other facility (e.g., hotel, hospital, school, airplane, etc.). With reference to  FIGS. 25 and 26 , one or more passageways  1930  or other inlets of a bed assembly  1910  can be placed in fluid communication with a register R or other outlet of a main HVAC system (e.g., central air) or other climate control system, using an interconnecting duct  1920  or other conduit. Such an interconnecting duct  1920  can be configured to secure to (or replace) a standard register R, a non-standard register, other outlet and/or the like. In other embodiments, the interconnecting duct  1920  is flexible or substantially flexible to facilitate the connection to the register R and/or to accommodate movement of the bed  1910  relative to the floor or walls. 
     With continued reference to  FIG. 25 , an interconnecting duct  1920  can be connected to a passageway  1930  (or other internal or external conduit) along the bottom, side and/or any other portion of the bed assembly  1910 . Such a duct  1920  can be connected to passageways  1930  of the bed assembly that are in fluid communication with one or more of climate zones, as desired or required. As shown in  FIG. 26 , a register R or other outlet of the HVAC system can be positioned along the floor, wall or any other area of a room. Alternatively, a bed assembly can be placed in fluid communication with a hose H or other conduit that receives conditioned air from a main HVAC system or other climate control system. In the arrangement illustrated in  FIG. 26 , such a hose H can be routed through an opening O of the wall. However, in other embodiments, the hose H or other conduit can be accessed through an opening positioned along the floor, ceiling or any other location. In some arrangements, a home or other facility can be built or retrofitted with such HVAC connections and other components (e.g., hoses, other conduits, openings, etc.) in mind. 
       FIG. 27  illustrates another embodiment of a climate controlled bed assembly  2010  which is in fluid communication with a home&#39;s or other facility&#39;s HVAC system using an interconnecting duct  2020 . As shown, the interconnecting duct  2020  can be connected to a register R that is positioned along an adjacent wall. In some embodiments, the interconnecting duct  2020  can comprise a tube or other conduit that can be easily flexed or otherwise manipulated to complete the necessary connections between the register R and the passageways  2030  of the bed  2010 . For example, the interconnecting duct  2020  can comprise plastic, rubber and/or any other flexible materials. In other embodiments, the interconnecting duct  2020  comprises bellows, corrugations and/or other features that provide it with the desired flexible properties. 
     Placing one or more climate zones of a bed assembly in fluid communication with a HVAC system or other climate control system can offer certain advantages, regardless of the manner in which such a connection is accomplished. For example, under such systems, the need for separate fluid modules as part of the bed assembly can be eliminated. Thus, heated, cooled, dehumidified and/or otherwise conditioned air can be delivered directly to the bed assembly. Consequently, a less complicated and more cost-effective bed assembly can be advantageously provided. Further, the need for electrical components can be eliminated. One embodiment of such a bed assembly  2110  is schematically illustrated in  FIG. 28A . As shown, one or more interconnecting ducts  2120 ′,  2120 ″,  2120 ′″ can be used to place the bed  2110  in fluid communication with a main HVAC system. As discussed, the ducts can be secured to registers, outlets, hoses and/or other conduits positioned along a wall W and/or the floor F of a particular room. 
     In other embodiments, conditioned air can be provided from a home&#39;s or other facility&#39;s HVAC system into the inlet of one or more fluid modules of the bed assembly. This can result in a more energy efficient and cost effective system, as the amount of thermal conditioning (e.g., heating, cooling, etc.) required by the fluid modules or other components of the bed assembly may be reduced.  FIG. 28B  schematically illustrates one embodiment of such a climate controlled bed assembly  2210 . As shown, one or more interconnecting ducts  2220 ′,  2220 ″,  2220 ′″ can be used to direct air from a main HVAC system to one or more fluid modules. In some embodiments, as discussed in greater detail herein, the fluid modules are positioned within a lower portion of a bed assembly. Thus, the interconnecting ducts can deliver conditioned air into the interior of such a lower portion. In other arrangements, however, conditioned air is delivered directly into the inlet of one or more fluid modules. 
     As schematically illustrated in  FIG. 29A , an interconnecting duct  2320  can be configured to receive one or more additional fluid sources  2360 . Consequently, the air being transferred from a register R or other outlet of a central HVAC system can be selectively combined with an external source  2360  of fluids and/or other substances, as desired or required. This additional fluid and/or other substance being delivered to the bed  2310  can provide certain benefits. For example, in some embodiments, one or more medications are selectively combined with HVAC air and delivered to a fluid distribution system of the bed  2310  (e.g., inlet, internal passageways  2330 , etc.). Any type of pharmaceuticals (e.g., prescription, over-the-counter), homeopathic materials, other therapeutic substances and/or other medicaments can be delivered to the bed  2310 , including, but not limited to, asthma medications, anti-fungal or anti-bacterial medications, high-oxygen content air, sleep medication and/or the like. In embodiments where the bed includes a medical bed, wheelchair or other seating assembly located within a hospital or other medical facility, physicians, nurses or other medical professionals can oversee the administration of one or more medications and other substances for therapeutic, pain-relief or any other purpose. 
     In other embodiments, the bed is adapted to receive other types of fluids or substances from the fluid source  2360 , either in addition to or in lieu of HVAC air and/or medicaments. For example, insect repellent (e.g., citronella, Deet, etc.) can be provided to a bed situated in an environment in which bugs present health risks or a general nuisance. In certain arrangements, fragrances and/or other cosmetic substances are delivered to the bed to help create a desired sleeping or comfort environment. Any other liquid, gas, fluid and/or substance can be selectively provided to a climate control bed, as desired or required. 
     With continued reference to  FIG. 29A , delivery conduit  2350  can be used to place the fluid source  2360  in fluid communication with the interconnecting duct  2320 . In the illustrated embodiment, the fluid source  2360  and the delivery conduit  2350  are positioned at a location exterior to the bed assembly  2310 . Alternatively, the fluid source  2360  and/or the delivery conduit  2350  can be positioned at least partially within one or more portions of the bed  2310  or other seating assembly. For example, the fluid source  2360  and/or the accompanying delivery conduit  2350  can be positioned within or on a side of the bed  2310  (e.g., mattress or other upper portion, box spring or other lower portion, etc.). Thus, the fluid source  2360  and/or the accompanying delivery conduit  2350  can be configured to not tap or otherwise connect into a HVAC interconnecting duct. In some embodiments, such as the one illustrated in  FIG. 29C , a fluid source  2360 ′ is configured to be placed within a dedicated compartment  2362 ′, so that it is generally hidden from view. Additional details regarding such an arrangement are provided below. 
     According to some arrangements, a fluid transfer device (e.g., pump) is used to transfer a desired volume of a fluid from the fluid source  2360  to the conduit  2350  and/or other hydraulic components (e.g., interconnecting duct  2320 , fluid distribution system of a bed or other seating assembly, etc.). Alternatively, the fluids and/or other materials contained within a fluid source  2360  can be delivered to the bed or other seating assembly using one or more other devices or methods, such as, for example, an ejector (or other Bernoulli-type device), gravity or the like. 
     As discussed herein and illustrated in the arrangement of  FIG. 29B , a delivery conduit  2350  can be used to place a fluid source in fluid communication with an interconnecting duct  2320 . In depicted embodiment, the interconnecting duct  2320  is configured to convey air from a register R or other outlet of a main HVAC system to an inlet passageway  2330  of a climate controlled seating assembly  2310  (e.g., a bed, a seat, a wheelchair, etc.). In some arrangements, a coupling  2354  (e.g., quick-connect, other type of coupling, etc.) is located at or near the connection point between the delivery conduit  2350  and the interconnecting duct  2320 . Such a coupling or other device can facilitate the manner in which the delivery conduit  2350  is connected to or detached from the interconnecting duct  2320 . Thus, in some embodiments, the delivery conduit  2350  can be placed in fluid communication with the fluid distribution system of a bed or other seating assembly (e.g., via an interconnecting duct  2320 ) only when the addition of a medicant and/or any other substance of a fluid source  2360  are desired or required. Further, the system can include one or more check valves, other flow-control or flow-regulating devices and/or other hydraulic components to ensure that fluids are not inadvertently routed in undesirable directions through the various conduits and other components of the system. 
       FIG. 29C  schematically illustrates one embodiment of a fluid source  2360 ′ contained within an internal compartment  2362 ′, cavity or other interior portion of a bed  2310 ′ or other seating assembly. As shown, the fluid source  2360 ′ can be placed in fluid communication with a fluid distribution system  2330 ′ (e.g., channel, conduit, passageway, etc.) of the bed using a delivery conduit  2350 ′. As discussed herein with reference to other embodiments, the medications, other fluids and/or any other substance contained within the fluid source  2360 ′ can be selectively transferred to the fluid distribution system  2330 ′ of the bed assembly using a fluid transfer device (e.g., a pump), an ejector or other Bernoulli-type mechanism, gravity and/or any other device or method. Further, the bed assembly  2310 ′ can comprise one or more valves and/or other flow-regulating devices or features to help ensure that fluids and other materials are delivered to the distribution system  2330 ′ of the bed in accordance with a desired or required manner. 
     As discussed above, a separate fluid source does not need to be connected to a HVAC system configured to provide environmentally-conditioned air (e.g., heated or cooled air, ambient air, humidity-modified air, etc.) to a seating assembly. For example, as illustrated in  FIG. 30 , a bed assembly  2410  can include separate conduits  2420 ,  2450  that are configured to place a register R or other outlet of a HVAC system and a separate fluid source  2460  in fluid communication with the assembly. Further, in any of the embodiments disclosed herein, a bed or other climate controlled seating assembly can be configured to receive medications and/or other materials from a separate fluid source  2460  without being adapted to receive air from a HVAC system. 
     In any of the various embodiments disclosed herein, or variations thereof, a fluid source can include a container (e.g., a tank, reservoir, bottle, vial, ampoule, gel-pack, etc.) that is otherwise configured to be used with a climate controlled seating assembly. For example, such a container can be sized and shaped to fit within the internal compartment  2362 ′ of the assembly illustrated in  FIG. 29C . Further, such containers can be adapted to be quickly and easily installed, removed and/or replaced by users, thereby permitting users to change the medication, insect repellent, fragrance and/or any other substance being delivered to and through the seating assembly (e.g., bed). 
     In some arrangements, information regarding the temperature, flowrate, humidity level and/or other characteristics or properties of conditioned air being conveyed in a HVAC system can be detected and transmitted (e.g., using hardwired or wireless connections) to a control module (e.g., ECU) of the bed&#39;s climate control system. Accordingly, the bed&#39;s climate control system can adjust one or more devices or settings to achieve a desired cooling and/or heating effect one or more bed occupants. The interconnecting ducts can include one or more valves (e.g. modulating valves, bleed valves, bypass valves, etc.) or other devices to selectively limit the volume of air being delivered to the bed assembly. For example, the entire stream of pre-conditioned air may need to be diverted away from the climate controlled bed assembly in order to achieve a desired cooling or heating condition along the top surface of the bed. Any of the embodiments of a climate controlled bed assembly disclosed herein, or equivalents thereof, can be placed m fluid communication with a main HVAC system. 
     According to certain embodiments, the various control modules of the bed&#39;s climate control system are configured to receive information (e.g., temperature, flowrate, humidity, etc.) regarding the air being delivered from a main HVAC system to one or more climate zones of the bed assembly. As a result, the climate module can use this information to achieve the desired cooling, heating and/or ventilation effect for each climate zone, either with or without the assistance from the various thermal modules. In some arrangements, the air being delivered to the bed&#39;s climate control system can be regulated (e.g., by dampers, valves, bleed-offs, modulators, etc.) in order to achieve the desired thermal conditioning along one or more portions of the bed assembly. 
     In some arrangements, data or information related to the temperature and/or humidity of the room in which the bed assembly is transmitted to the bed&#39;s climate control system. In one embodiment, such data can be provided to the user via a user input device and/or any other component or device. In alternative arrangements, information regarding a bed&#39;s climate zone(s), the operation of the fluid modules and/or any other operational aspect of the bed can be transmitted and/or displayed by a controller (e.g., thermostat) of the home&#39;s main HVAC system. Accordingly, one or more environmentally conditioned bed assemblies can be advantageously controlled using a home&#39;s thermostat or other controller. Similarly, one or more user input devices can be used to adjust or otherwise control the operation of the home&#39;s main HVAC system. 
     According to some embodiments, a climate control bed or other seating assembly can constitute merely one component of a larger zonal cooling system. As discussed herein, a bed can be placed in fluid and/or data communication with one or more HVAC systems (e.g., central heating and cooling unit, furnace, other thermal conditioning device, etc.) or other thermal conditioning devices or systems of a home or other facility (e.g., hospital, clinic, convalescent home or other medical facility, a hotel, etc.). As a result, the climate control system of the bed or other seating assembly located within a particular room or area can be operatively connected to the control system of one or more other climate control systems (e.g., main HVAC system). Thus, such configurations can be used to operate the climate controlled bed (or other seating assembly, e.g., medical bed, wheelchair, sofa, other chair, etc.) and a building&#39;s other climate control system in a manner that helps achieve one or more objectives. For example, under an energy efficiency mode, when a climate controlled bed is in operation, the level of cooling, heating or ventilation occurring within the corresponding room or area of a building can be advantageously reduced or eliminated. In such an embodiment, the bed or other seating assembly can be viewed as a smaller climate control zone within a larger climate control zone (e.g., the room). 
     Alternatively, when the bed is not being used, the home&#39;s or other facility&#39;s HVAC control system can be configured to operate in a manner that achieves a desired comfort level (e.g., temperature, humidity, etc.) within the entire room or area in which the seating assembly is positioned. 
     In other arrangements, a room (or other defined or undefined area) is operated so as to achieve a first conditioning effect (e.g., cooling, heating, ventilation, etc.) within the entire room and a second conditioning effect specific only to a bed or other seating assembly positioned within that room. Thus, depending on the control algorithm being used, a main HVAC system may or may not be operating at the same time as a climate control system for a bed (or other seating assembly). In certain embodiments, however, regardless of the exact operational scheme being utilized, the climate control system of a seating assembly is operatively connected to and working in cooperation with the control system of a home&#39;s or other facility&#39;s HVAC system (e.g., central air, furnace, etc.). 
     A climate controlled bed or other seating assembly can include one or more sensors (e.g., temperature sensors, moisture sensors, humidity sensors, etc.). As discussed in greater detail herein, such sensors can be used to operate the climate control system of the assembly within a desired range or zone. However, the use of such sensors on, within or near a bed or other seating assembly can provide additional benefits and advantages. For example, one or more temperature sensors can be positioned along an upper portion of a bed, medical bed, wheelchair or other seating assembly (e.g., at or near the location where an occupant is expected to be positioned). Such sensors can help detect the body temperature of an occupant. In some embodiments, such measurements can be transmitted to an alarm, display, other output, control unit, processor and/or other device or component, so as to alert the occupant and/or interested third parties of the occupant&#39;s body temperature. 
     Such arrangements can be particularly beneficial in hospitals or other medical facilities where it is important to closely monitor patients&#39; vital signs (e.g., to notify the proper personnel of a patient&#39;s fever, hypothermia, etc.). Further, such a configuration can be used in a home or other setting to monitor the body temperature of infants, toddlers, young children, the elderly, the infirmed and/or the like. In other embodiments, a bed or other seating assembly is configured to use the body temperature measurements to make corresponding changes to the assembly&#39;s climate control system (e.g., increase or decrease the heating, cooling or ventilation effect), as desired or required by a particular control scheme. 
     In other arrangements, a seating assembly (e.g., bed, medical bed, wheelchair, etc.) includes one or more moisture sensors. Such sensors can be positioned along the top of the seating assembly, along an interior of the top portion (e.g., mattress) and/or at any other location. Regardless of their exact quantity, type, location and other details, such moisture sensors can be configured to detect the presence of water, sweat, urine, other bodily fluids and/or any other liquid or fluid. As discussed herein with reference to body temperature sensors, moisture sensors can also be operatively connected to one or more alarms, monitors, control units, other processors and/or the like. Accordingly, the occupant and/or interested third parties can be promptly informed about the presence of moisture at or near one or more sensors. Such embodiments can be particularly helpful in monitoring people (e.g., children, elderly, infirmed, etc.) who are prone to wetting their beds or other seating assemblies (e.g., wheelchair, chair, etc.). Further, such arrangements can be desired where it is desired to detect the presence of sweat or other fluids that may be discharged by an occupant. 
       FIG. 31  schematically illustrates one embodiment of a climate controlled bed assembly  2510  and various components and systems that are operatively connected to it. The bed can be configured according to any of the embodiments presented herein or equivalents thereof. As shown, the bed  2510  can include two or more different zones, areas or portions that may be operated independently of one another. In the depicted arrangement, the bed  2510  comprises a total of four climate zones  2511 A- 2511 D. Alternatively, a bed  2510  or other seating assembly can include more or fewer climate zones, as desired or required. 
     With continued reference to  FIG. 31 , two of the climate zones  2511 A,  2511 C are positioned along the left side L of the bed  2510 , whereas two of the climate zones  2511 B,  2511 D are situated along the right side R of the bed  2510 . In the depicted embodiment, each side of the bed (e.g., the left side Land the right side R) is further divided into two zones or areas. By way of example, the left side L includes a first climate zone  2511 A located along an upper portion of the bed  2510  and a second climate zone  2511 C located along a lower portion of the bed  2510 . Such zones can permit an occupant to selectively adjust the climate control effect on his or her side of the bed, as desired or required. For instance, a bed occupant positioned along the left side L may choose to operate the first climate zone  2511 A at a warmer or cooler setting than the second climate zone  2511 B. Such configurations can advantageously allow a user to customize the heating, cooling and/or ventilation effect on his or her side of the bed  2510  without influencing the desired heating, cooling and/or ventilation effect of a second user. 
     According to some embodiments, air or other fluid is supplied to each climate zone  2511 A- 2511 D using one or more thermal modules  2520 A- 2520 D. For example, in  FIG. 31  each climate zone  2511 A- 2511 D comprises one thermal module  2520 A- 2520 D. Accordingly, each occupant can regulate the flow of thermally-conditioned and/or ambient air or other fluids that are delivered toward his or her side of the bed assembly  2510 . Further, as discussed, two or more climate zones can be provided along a portion of the bed intended to support a single occupant. Thus, an occupant can advantageously adjust the cooling, heating and/or ventilation effect along various regions of his or her side of the bed  2510  (e.g., head or neck area, leg area, main torso area, etc.), as desired. 
     As discussed in greater detail herein with reference to other embodiments, each thermal module  2520 A- 2520 D can comprise a fluid transfer device (e.g., a blower, fan, etc.), a thermoelectric device (e.g., a Peltier circuit) or any other heating or cooling device capable of thermally conditioning a fluid (e.g., a convective heater), one or more sensors, other control features and/or any other component or feature, as desired or required. For convenience and ease of installation, some or all of these components can be included within a single housing or other enclosure. As discussed in greater detail, each thermal module  2520 A- 2520 D can be advantageously adapted to selectively provide thermally-conditioned (e.g., cooled, heated, etc.) and/or thermally-unconditioned (e.g., ambient) air or other fluids toward one or more bed occupants. 
     For example, with reference to the cross-sectional view of  FIG. 32A , a mattress  2512 ′ or other upper portion of the bed assembly  2510 ′ can include one or more internal passages  2513 ′ or conduits through which fluids may be directed. In some embodiments, as shown in  FIG. 252A , the thermal modules  2520 A′,  2520 B′ are positioned generally below the mattress  2512 ′ or other upper portion and are placed in fluid communication with one or more of the internal passages  2513 ′. Accordingly, fluids can be selectively delivered from each thermal module  2520 A′,  2520 B′ to a fluid distribution member  2518 ′ located at or near an upper portion of the bed assembly  2510 ′ to create the desired heating, cooling and/or ventilation effect along that corresponding region or area of the bed. In any of the arrangements disclosed herein, adjacent climate zones  2511 A- 2511 D of a bed assembly can be partially or completely isolated (e.g., thermally, hydraulically, etc.) from each other, as desired or required. Alternatively, adjacent climate zones can be configured to generally blend with one another, without the use of specific thermal or hydraulic barriers separating them. In other embodiments, the manner in which environmentally (e.g., thermally) conditioned and/or unconditioned fluids are directed to an upper portion of a bed assembly can be different than illustrated in  FIG. 32A . 
     Alternatively, as discussed in greater detail herein, one or more of the passages or conduits of a bed assembly can be configured to receive air or other fluids from a home&#39;s main HVAC system (e.g., home air-conditioning and/or heating vent) and to selectively deliver such fluids toward one or more occupants situated on the bed. Additional disclosure and other details regarding different embodiments of climate controlled beds can be found in U.S. Publication No. 2008/0148481, titled AIR-CONDITIONED BED, the entirety of which is hereby incorporated by reference herein. 
     Regardless of their exact design, thermally-controlled bed assemblies can be configured to selectively provide air or other fluids (e.g., heated and/or cooled air, ambient air, etc.) to one or more occupants positioned thereon. Thus, the incorporation of various climate zones  2511 A- 2511 D in abed  10  can generally enhance an occupant&#39;s ability to control the resulting heating, cooling and/or ventilation effect. For example, such a bed can be adapted to create a different thermally-conditioned environment for each occupant. In addition, a particular occupant can vary the heating, cooling and/or ventilation scheme within his or her personal region or space (e.g., the head area of the bed can be operated differently than the midsection or lower portion of the bed). 
     With continued reference to the schematic of  FIG. 31 , the thermal modules  2520 A- 2520 D of the bed assembly  2510  can be operatively connected to a climate control module  2550  or other electronic control unit (ECU). As shown, the control module  2550  can be in a location remote to the bed  2510 . Alternatively, the control module  2550 , ECU and/or other control unit can be incorporated into one or more portions of the bed assembly (e.g., backer board of the foundation, box spring, other support member, etc.). In turn, the control module  2550  can be operatively connected to a power source  2554  that is configured to supply the necessary electrical current to the various electronic components of the climate control system, such as, for example, the fluid transfer device, the thermoelectric device and/or other portion of the thermal modules  2520 A- 2520 D, the control module  2550  itself, the user input devices  2562 ,  2564  and/or any other item, device or system. 
     According to certain arrangements, the power source  2554  comprises an AC adapter having a cable  2560  that is configured to be plugged into a standard wall outlet, a DC adapter, a battery and/or the like. As illustrated schematically in  FIG. 31 , the control module  2550  and the electrical power source  2554  can be provided within a single housing or other enclosure  2540 . However, in alternative embodiments, the control module  2550  and the power source  2554  can be provided in separate enclosures, as desired or required. 
     As illustrated in  FIG. 31 , two or more thermal modules  2520 A- 2520 D of a bed assembly  2510  can be operatively connected to each other. Such cross-connections can facilitate the transmission of electrical current and/or data from the thermal modules  2520 A- 2520 D to other portions of the climate control system, such as, for example, the control module  2550  or other ECU, a power source  2554 , a user input device  2562 ,  2564  and/or the like. The connections between the different electrical devices, components and/or systems of a climate control bed assembly can be hardwired (e.g., using a cable, cord, wire, etc.) and/or wireless (e.g., radio frequency, Bluetooth, etc.), as desired or required by a particular application or use. According to some embodiments, the thermal modules adapted to deliver fluids to a single side of the bed  2510  (e.g., the left side L, the right side R, etc.) are connected to each using one or more hardwired and/or wireless connections. For instance, in  FIG. 31 , the two thermal modules  2520 A,  2520 C on the left side L of the bed  2510  are operatively connected to each other. Likewise, the two thermal modules  2520 B,  2520 D on the right side R are also connected to one another. Thus, as depicted, a single connection can be used to transfer electrical power, other electrical signals or communications and/or the like to and/or from each paring or other grouping of thermal modules  2520 A- 2520 D. The manner in which the various thermal modules, control units and/or other components of the climate control system are arranged can vary. 
     With continued reference to  FIG. 31 , the bed&#39;s climate control system can additionally include one or more user input devices  2562 ,  2564 . Such user input devices  2562 ,  2564 , which in the depicted embodiment are operatively connected to the control module  2550 , are configured to permit a user to selectively regulate the manner in which the climate control system is operated. As with other electrical components of the climate control system, the user input devices  2562 ,  2564  can be connected to the control module  2550  and/or any other component using a hardwired and/or wireless (e.g., radio frequency, Bluetooth, etc.) connection. 
     According to certain embodiments, a user input device  2562 ,  2564  comprises at least one controller that is configured to regulate one or more operational parameters of the climate controlled bed assembly  2510 . A user input device  2562 ,  2564  can include one or more buttons (e.g., push buttons), switches, dials, knobs, levers and/or the like. Such controllers can permit a user to select a desired mode of operation, a general heating, cooling and/or ventilation scheme, a temperature setting or range and/or any other operational parameter. For instance, in some arrangements, the input device  2562 ,  2564  allows users to select between “heating,” “cooling” or “ventilation.” In other embodiments, the controllers of the input device can be adjusted to select a particular level of heating, cooling or ventilation (e.g., low, medium, high, etc.) or a preferred temperature for the fluid being delivered toward an occupant positioned along an upper surface of the bed  2510 . 
     Alternatively, an input device  2562 ,  2564  can be configured to provide various data and other information to the user that may be relevant to the operation of the bed  2510 . For example, the input device can comprise a display (e.g., LCD screen) that is adapted to show the current mode of operation, a real-time temperature or humidity reading, the date and time and/or the like. In certain embodiments, the input device comprise a touchscreen display that is configured to both provide information to and receives instructions from (e.g., using softkeys) a user. As discussed in greater detail herein, a user input device  2562 ,  2564  can be configured to also control one or more other devices, components and/or systems that are generally unrelated or only remotely-related to the operation of the climate control system, such as, for example, a digital music player, a television, an alarm, a lamp, other light fixture, lights and/or the like, as desired or required. In some arrangements, the user input devices  2562 ,  2564  of a bed assembly  10  can be operatively connected to such other devices, components or systems using one or more hardwired and/or wireless connections. 
     In some arrangements, a user input device is customized according to a customer&#39;s needs or desires. As discussed herein, for example, the user input device can be configured to allow an occupant to regulate one or more aspects of the bed&#39;s climate control system (e.g., setting a target thermal conditioning or temperature setting along a top surface of the bed). Further, a user input device  2562 ,  2564  can be adapted to regulate other devices or systems, even if such devices or systems are not directly related to the bed assembly  2510 . For instance, an input device can control one or more aspects of a digital medial player (e.g., iPod, mp3 player, etc.), a television, a lamp, a home&#39;s lighting system, an alarm clock, a home&#39;s main HVAC system (e.g., central air-conditioning and/or heating system) and/or the like. A user input device can include one or more hardwired and/or wireless connections in order to properly communicate with such other devices or systems. According to some embodiments, input devices are supplied to end users already configured to be used with one or more other devices and/or systems. Alternatively, however, a user may need to at least partially program or otherwise set-up an input device to operatively connect it to one or more ancillary devices or systems (e.g., using specific manufacturers&#39; codes of the devices or systems with which the input device will be operatively connected). 
     Moreover, a user input device  2562 ,  2564  can include a touchscreen or other display that is configured to provide information about the climate control bed assembly and/or any other device or system that is controlled or otherwise operatively connected to the input device. For example, such a display can indicate the specific operational mode under which the climate control system is operating, a target temperature setpoint or range that the climate control system is programmed to achieve, the temperature, humidity and/or other measurements related to the ambient environment of the room in which the bed is located, the date and time, the status of an alarm or other feature with which the bed&#39;s control unit is operatively connected, information regarding a digital media player or television to which the input device is operatively connected (e.g., a song title, television program title and other information, etc.) and/or the like. In addition, a user input device can be further personalized using skins or other decorative features, as desired or required. 
     A climate control bed assembly can be alternatively controlled, at least in part, by one or more other devices or systems, either in lieu of or in addition to a user input device. For example, in certain embodiments, a user can regulate the operation of the bed assembly (e.g., select a mode of operation, select an operating temperature or range, initiate a specific operating scheme or protocol, etc.) and/or control any other devices or systems with which the bed assembly is operatively connected using a desktop device (e.g., a personal computer), a personal digital assistant (PDA), a smartphone or other mobile device and/or the like. In other arrangements, the climate control system of a climate conditioned bed can be in data communication with a wall-mounted device, such as, for example, a thermostat for a home HVAC system. Thus, a single controller can selectively modify the operation of a home&#39;s central air-conditioning and heating system and one or more climate controlled bed assemblies. Moreover, as discussed in greater detail herein with reference to  FIGS. 25-30 , the home&#39;s HVAC system can be placed in fluid communication with one or more fluid passages, conduits or other portions of a bed assembly. 
     A climate control system for a bed assembly  2510  can be additionally configured to continuously or intermittently communicate with one or more networks to receive firmware and/or other updates that help ensure that the system is operating correctly. For example, the control module  2550 , user input devices  2562 ,  2564  and/or any other component of the climate control system can be designed to connect to a network (e.g., internet). In some embodiments, the bed assembly is operatively connected to a manufacturer&#39;s or supplier&#39;s website to receive the necessary updates or patches. In other arrangements, such network connections can facilitate the repair, maintenance or troubleshooting of the climate control bed assembly, without the need for an on-site visit by a technician. 
     A user input device can be adapted for use with different climate control systems for beds or other seating assemblies. For instance, a user input device can comprise a cable or other hardwired connection that is sized, shaped and otherwise adapted to be received by a corresponding port or coupling of a control module or other portion of the climate control system. Likewise, in embodiments where the user input device is wireless (e.g., remote control, other handheld, etc.), the input device can be configured to operate with two or more different climate control systems. This can help create a modular system in which one or more components of a thermally-conditioned bed or other seating assembly are combined without the need for complicated and/or time-consuming re-designs. 
     According to certain arrangements, each user input device  2562 ,  2564  is adapted to regulate one or more thermal modules, climate zones and/or other devices or components of a climate controlled bed assembly  2510 . For example, with continued reference to the schematic of  FIG. 31 , a first user input device  2562  can regulate the operation of the thermal modules  2520 A,  2520 C, and thus, the corresponding climate zones  2511 A,  2511 C, situated along the left side L of the bed  2510 . Likewise, a second user input device  2564  can regulate the operation of the thermal modules  2520 B,  2520 D, and thus, the corresponding climate zones  2511 B,  2511 D, situated along the right side R of the bed  2510 . Consequently, each bed occupant can selectively regulate the heating, cooling and/or ventilation scheme along his or her side of the bed  2510 . Moreover, as discussed herein, a bed can include two or more different thermal modules  2520 A- 2520 D and/or climate zones  2511 A- 2511 D within a region sized and otherwise configured to receive a single occupant. Accordingly, in certain embodiments, an input device  2562 ,  2564  is capable of regulating one thermal module (or climate zone) separately and independently from another thermal module (or climate zone), as desired. Thus, as depicted in  FIG. 31 , an input device  2562 ,  2564  can be advantageously configured to control one, two or more thermal modules or climate zones generally located along one side (e.g., the left side L, right side S, etc.) or any other region of the bed assembly  2510 . 
     According to certain arrangements, the various devices, components and features of a climate controlled bed assembly  10  are configured to adjust the type and/or level of heating, cooling and/or ventilation by modifying the operation of the thermal modules  2520 A- 2520 D. For example, the rate at which fluids are transferred toward an occupant (e.g., using a blower, fan or other fluid transfer device) can be advantageously controlled. Further, the amount and direction of electrical current delivered to the thermoelectric device can be altered to achieve a desired level of heat transfer to or from the fluid transferred by the fluid transfer device. One or more other aspects of the systems can also be modified to achieve a desired operational scheme. 
     In order to achieve a desired thermal conditioning effect in each climate zone  2511 A- 2511 D, the thermal modules  2520 A- 2520 D, other components of the climate control system and/or other portions of the bed  2510  can comprise one or more sensors. Such sensors can include temperature sensors, humidity sensors, occupant-detection sensors and/or the like. Accordingly, the climate control system can advantageously maintain a desired level of thermal conditioning (e.g., a setting, temperature value or range, etc.). The temperature sensors can be positioned within a thermoelectric device (e.g., on or along the substrate of the thermoelectric device), within or on other portions or components of the thermal module, upstream or downstream of a thermal module (e.g., within or near a fluid path to detect the amount of thermal conditioning occurring within the thermal module), along one or more top surfaces of the bed assembly  2510  and/or at other location. 
     According to one embodiment, a thermally-conditioned bed assembly  2510  comprises a closed-loop control scheme, under which the function of one or more thermal modules (e.g., blower or other fluid transfer device, thermoelectric device or other heating/cooling device and/or the like) is automatically adjusted to maintain a desired operational setting. For example, the climate control system can be regulated by comparing a desired setting (e.g., a target temperature value or range, a target cooling, heating or ventilation effect, etc.) to data retrieved by one or more sensors (e.g., ambient temperature, conditioned fluid temperature, relative humidity, etc.). 
     In certain arrangements, a climate control system for a bed or other seating assembly can comprise a closed-loop control scheme with a modified algorithm that is configured to reduce or minimize the level of polarity switching occurring in one or more of the thermoelectric devices of the thermal modules  2520 A- 2520 D. As a result, the reliability of the overall climate control system can be advantageously improved. 
     As discussed in greater detail herein, a thermally-conditioned bed  2510  or other seating assembly can include one, two or more different climate zones  2511 A- 2511 D. In some embodiments, as illustrated schematically in  FIG. 31 , such a bed  2510  includes separate climate zones for each occupant. Further, the area or other portion associated with each occupant (e.g., left side L, right side R, etc.) can include two or more distinct climate zones  2511 A- 2511 D, allowing an occupant to further customize a heating, cooling and/or ventilation scheme according to his or her preferences. Thus, as discussed above, a user can configure his or her side of a bed assembly  2510  to provide varying levels of thermal conditioning to different portions of the bed (e.g., top or head area, midsection area, lower or leg area, etc.), as desired or required. 
     A climate controlled bed or other seating assembly can be operated under a number of different schemes. For example, in a simple configuration, a user selects a desired general setting or mode (e.g., “heating,” “cooling,” “ventilation,” “high,” “medium,” “low,” etc.) and the climate control system maintains such a setting or mode for a particular time period or until the user instruct the system otherwise. In other arrangements, a user chooses a target temperature value or range or some other desired cooling, heating or ventilation effect, and the climate control system automatically makes the necessary adjustments to maintain such a value, range or effect. Under such a scheme, the climate control system can comprise one or more sensors (e.g., temperature sensors, humidity sensors, etc.) that are adapted to facilitate the system to achieve the desired settings (e.g., using feedback loops). In other embodiments, the various components of a climate controlled bed can be operated according to a predetermined schedule or protocol. Such schedules or protocols can be based on time of day, the time when a user typically or actually goes to bed, projected or actual wake-up time, the ambient temperature within or outside the room where the bed is located and/or any other factor. Accordingly, the control module  50  and/or other component of the climate control system can comprise or be operatively connected to a control algorithm that helps execute a particular protocol. 
     In any of the embodiments disclosed herein, the control system can be operatively connected to one or more input devices  2562 ,  2564  that advantageously permit users to selectively modify the operation of the environmentally conditioned bed or other seating assembly. As discussed in greater detail herein, such input devices can allow a user to customize the manner in which the bed or other assembly is controlled, in accordance with the user&#39;s desires or preferences. 
     According to certain embodiments, a climate control system for a bed or other seating assembly can be adapted to provide a desired level of thermal pre-conditioning. Such a pre-conditioning feature can allow a user to program a bed so that it achieves a particular temperature or setting prior to use. For example, a user can use an input device to direct the climate control system to cool, heat and/or ventilate the bed prior to the user&#39;s anticipated sleep time. Likewise, a user can selectively program a climate control system to regulate the temperature or thermal-conditioning effect during the anticipated sleep period. In such arrangements, a user can set a different target temperature, thermal conditioning effect, desired comfort level and/or any other setting for a specific time period. Such setpoints can be programmed for various desired or required time intervals (e.g., 10 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours, etc.). Accordingly, a user can customize the operation of a climate controlled bed assembly according to his or her specific needs and preferences. 
     Further, the control system can be configured to change the heating, cooling and/or ventilation settings of the bed to help a user wake up, as desired or required. For example, the flowrate, temperature and/or other properties of the air delivered to the top surfaces of a bed can be increased or decreased to help awaken an occupant or to urge an occupant to get out of bed. 
     Moreover, a climate control system for a bed or other seating assembly can be adapted to shut down after the passage of a particular time period and/or in response to one or more other occurrences or factors. In certain arrangements, the operation of one or more thermal modules is altered (e.g., the speed of the fluid transfer device is reduced or increased, the heating and/or cooling effect is reduced or increased, etc.) or completely terminated at a specific time or after a predetermined time period following an occupant initially becomes situated on a bed or other seating assembly. Accordingly, in some embodiments, the bed or other seating assembly includes one or more occupant sensors to accurately detect the presence of an occupant thereon. 
     As discussed herein, a climate-conditioned bed or other seating assembly can include one or more humidity sensors. Such humidity sensors can be positioned along any component of the bed&#39;s climate control system (e.g., user input devices, control module, thermal modules, etc.), any other portion of the bed assembly (e.g., mattress or upper portion, foundation or lower portion, etc.) and/or the like. Regardless of their exact configuration, location and other details, humidity sensors can be operatively connected to the climate control system to provide additional control options to a user. 
     According to certain arrangements, the relative humidity of the air or other fluids passing through the fluid modules, passages and/or other portions of a bed assembly can be detected to protect against the undesirable and potentially dangerous formation of condensate therein. For instance, if relatively humid air is sufficiently cooled by a thermal module, condensation may form along one or more components or portions of the assembly&#39;s climate control system. If not removed or otherwise handled, such condensation can cause corrosion and/or other moisture-related problems. Further, any condensation that results may negatively affect one or more electrical circuits or other vulnerable components of the climate control system. 
     Accordingly, in certain arrangements, a climate control system for a bed or other seating assembly is configured to make the necessary operational changes so as to reduce the likelihood of condensate formation. For example, the amount of cooling provided by the thermal modules (e.g., the thermoelectric devices or other cooling devices) to the air delivered through the bed assembly can be reduced. Alternatively, the control system can be configured to cycle between heating and cooling modes in an effort to evaporate any condensate that may have formed. In some arrangements, the temperature, relative humidity and other ambient conditions can be advantageously shown on a screen or display to alert the user of a potentially undesirable situation. 
     According to other embodiments, an environmentally-conditioned bed or other seating assembly is configured to collect and remove condensation that is formed therein. For example, such condensation can be evaporated or other channeled away from the bed or other seating assembly, as desired or required. Additional information regarding the collection and/or removal of condensate from seating assemblies is provided in U.S. patent application Ser. No. 12/364,285, filed on Feb. 2, 2009 and titled CONDENSATION AND HUMIDITY SENSORS FOR THERMOELECTRIC DEVICES, the entirety of which is hereby incorporated by reference herein. 
     In addition, the use of relative humidity sensors can permit an environmentally-conditioned bed or other seating assembly to operate within a desired comfort zone. One embodiment of such a comfort zone (generally represented by cross-hatched area  2610 ) is schematically illustrated in the graph  2600  of  FIG. 32B . As shown, a desired comfort zone  2610  can be based, at least in part, on the temperature and relative humidity of a particular environment (e.g., ambient air, thermally conditioned air, air which has had its humidity level modified and/or other fluid being delivered through a climate controlled bed or other seat assembly, etc.). Thus, if the relative humidity is too low or too high for a particular temperature, or vice versa, the comfort level to an occupant situated within such an environment can be diminished or generally outside a target area. 
     For example, with reference to a condition generally represented as point  2620 C on the graph  2600  of  FIG. 32B , the relative humidity is too high for the specific temperature. Alternatively, it can be said that the temperature of point  2620 C is too high for the specific relative humidity. Regardless, in some embodiments, in order to improve the comfort level of an occupant who is present in that environment, a climate control system can be configured to change the surrounding conditions in an effort to achieve the target comfort zone  2610  (e.g., in a direction generally represented by arrow  2620 C). Likewise, a climate control system for a bed or other seating assembly situated in the environmental condition represented by point  2620 D can be configured to operate so as to change the surrounding conditions in an effort to achieve the target comfort zone  2610  (e.g., in a direction generally represented by arrow  2620 D). In  FIG. 32B , environmental conditions generally represented by points  2620 A and  2620 B are already within a target comfort zone  2610 . Thus, in some embodiments, a climate control system can be configured to maintain such surrounding environmental conditions, at least while an occupant is positioned on the corresponding bed or other seating assembly. 
     In some embodiments, a climate control system for a bed is configured to include additional comfort zones or target operating conditions. For example, as illustrated schematically in  FIG. 32B , a second comfort zone  2614  can be included as a smaller area within a main comfort zone  2610 . The second comfort zone  2614  can represent a combination of environmental conditions (e.g., temperature, relative humidity, etc.) that are even more preferable that other portions of the main comfort zone  2610 . Thus, in  FIG. 32B , although within the main comfort zone  2610 , the environmental condition represented by point  2620 B falls outside the second, more preferable, comfort zone  2614 . Thus, a climate control system for a bed or other seating assembly situated in the environmental condition represented by point  2620 B can be configured to operate so as to change the surrounding conditions toward the second comfort zone  2614  (e.g., in a direction generally represented by arrow  2620 B). 
     In other embodiments, a climate control system can include one, two or more target comfort zones, as desired or required. For example, a climate control system can include separate target zones for summer and winter operation. In such arrangements, therefore, the climate control system can be configured to detect the time of year and/or the desired comfort zone under which a climate controlled bed or other seat assembly is to be operated. 
     The incorporation of such automated control schemes within a climate control system can generally offer a more sophisticated method of operating a climate-conditioned bed or other seat assembly. Further, such schemes can also help to simplify the operation of a climate controlled bed and/or to lower costs (e.g., manufacturing costs, operating costs, etc.). This can be particularly important where it is required or highly desirable to maintain a threshold comfort level, such as, for example, for patients in hospital beds, other types of medical beds and/or the like. Further, such control schemes can be especially useful for beds and other seating assemblies configured to receive occupants that have limited mobility and/or for beds or other seating assemblies where occupants are typically seated for extended time periods (e.g., beds, hospital beds, convalescent beds, other medical beds, etc.). 
     According to some embodiments, data or other information obtained by one or more sensors are used to selectively control a climate control system in order to achieve an environmental condition which is located within a desired comfort zone  2610 ,  2614  ( FIG. 32B ). For instance, a climate control system can include one or more temperature sensors and/or relative humidity sensors. As discussed in greater detail herein, such sensors can be situated along various portions of a bed or other seating assembly (e.g., thermoelectric device, thermal module, fluid distribution system, inlet or outlet of a fluid transfer device, fluid inlet, surface of an assembly against which an seated occupant is positioned, etc.) and/or any other location within the same ambient environment as the bed or other seating assembly (e.g., a bedroom, a hospital room, etc.). In other embodiments, one or more additional types of sensors are also provided, such as, for example, an occupant detection sensor (e.g. configured to automatically detect when an occupant is positioned on a bed or other seating assembly). 
     Regardless of the quantity, type, location and/or other details regarding the various sensors included within a particular assembly, the various components of the climate control system can be configured to operate (in one embodiment, preferably automatically) in accordance with a desired control algorithm. According to some embodiments, the control algorithm includes a level of complexity so that it automatically varies the amount of heating and/or cooling provided at the bed assembly based, at least in part, on the existing environmental conditions (e.g., temperature, relative humidity, etc.) and the target comfort zone. 
     Accordingly, m some embodiments, a control system for an environmentally-conditioned bed or other seating assembly is configured to receive, as inputs into its control algorithm, data and other information regarding the temperature and relative humidity from one or more locations. For example, a climate controlled bed can include fluid distribution systems  2518 ′ ( FIG. 32A ) located along the top of the support member (e.g., mattress) or any other portion. Each fluid distribution system  18 ′ can be in fluid communication with a thermal module  2520 A- 2520 D (e.g., a fluid transfer device, a thermoelectric device and/or the like). 
     Under some operational scenanos, such as, for example, when two or more thermal modules  2520 A- 2520 D are working at the same time, the noise level generated by a climate-conditioned bed may create a nuisance or otherwise become bothersome. Accordingly, in some embodiments, the control module or other portion of the climate control system is programmed to ensure that the thermal modules  2520 A- 2520 D are activated, deactivated, modulated and/or otherwise operated in a manner that ensures that the overall noise level originating from the bed or other seating assembly remains below a desired or required threshold level. For example, with reference to the bed assembly depicted in  FIG. 31 , the thermal modules  2520 A- 2520 D associated with each climate zone  2511 A- 2511 D can be cycled (e.g., turned on or off) to remain below such a threshold noise level. In some embodiments, the threshold or maximum noise level is determined by safety and health standards, other regulatory requirements, industry standards and/or the like. In other arrangements, an occupant is permitted to set the threshold or maximum noise level, at least to the extent provided by standards and other regulations, according to his or her own preferences. Such a setting can be provided by the user to the climate control system (e.g., control module) using a user input device. 
     Relatedly, the climate control system of a bed or other seating assembly can also be configured to cycle (e.g., turn on or off, modulate, etc.) the various thermal modules  2520 A- 2520 D in according to a particular algorithm or protocol to achieve a desired level of power conservation. Regardless of whether the thermal module cycling is performed for noise reduction, power conservation and/or any other purpose, the individual components of a single thermal module  2520 A- 2520 D, such as, for example, a blower, fan or other fluid transfer device, a thermoelectric device and/or the like, can be controlled independently of each other. Additional details regarding such operational schemes can be found in U.S. Publication No. 2009/0064411, titled OPERATIONAL CONTROL SCHEMES FOR VENTILATED SEAT OR BED ASSEMBLIES, the entirety of which is hereby incorporated by reference herein. 
     According to some embodiments, the power source  2554  (e.g., AC power supply) of the environmentally-conditioned bed or other seat assembly is sized for enhanced, improved or optimal cooling performance. As a result, such a design feature can help to further lower power consumption and allow the climate control system to operate more efficiently, as the amount of wasted electrical energy is reduced or minimized. 
     As discussed herein, any of the embodiments of a climate conditioned bed or other seating assembly disclosed herein can comprise a “thermal alarm.” For example, a climate control system can be configured to make a relatively rapid change in temperature and/or airflow to help awaken one or more of the bed&#39;s occupants. Depending on people&#39;s personal tendencies and sleep habits, such a thermal alarm can succeed in awakening a bed occupant as a result of decreasing comfort, raising awareness and/or in any other manner. In some arrangements, the thermal alarm includes raising the temperature along the top surface of the bed assembly. Such a feature can allow an occupant to wake up for naturally or gradually. Alternatively, depending on a user&#39;s preferences, the thermal alarm can include lowering the temperature to gradually or rapidly decrease an occupant&#39;s comfort level. A climate-conditioned bed assembly can also include one or more other types of alarms (e.g., a conventional audible alarm, an alarm equipped with a radio, digital media player or the like, etc.). In some arrangements, such alarm features and/or devices can be operatively connected to the control module of the climate control system to allow a user to regulate their function through an input device  2562 ,  2564  or any other controller. 
     According to certain embodiments, an environmentally-controlled bed assembly can be configured to advantageously provide thermally-conditioned air or other fluid along one or more regions of an occupant. For example, as schematically illustrated in  FIG. 33 , a bed assembly  2900  can include a pillow  2910  or other member that is configured to be placed in proximity to an occupant&#39;s head when the occupant is properly positioned thereon. Under certain circumstances, it may be desirable to provide cooled air toward an occupant&#39;s head and neck region (or any other portion of the bed), regardless of whether the bed is being operated under a heating or cooling mode. 
     As discussed with reference to other embodiments disclosed herein, the bed assembly  2900  can include one or more fluid modules  2920  that are adapted to selectively transfer fluids to target portions or areas of the bed and/or to selectively thermally-condition (e.g., heat, cool, etc.) such fluids before they are transferred. In the schematic of  FIG. 33 , the fluid module  2930  comprises an inlet  2930  through which ambient air or other fluids enter into a blower, other fluid transfer device and/or any other component of the module  2920 . In certain arrangements, fluid flow is generally separated at, within, near or downstream of the fluid module  2920  into a main fluid stream  2940  and a waste fluid stream  2950 . For example, when the bed is operated to provide cooled air to one or more upper surfaces, the main fluid stream  2950  is relatively cold while the waste fluid stream  2960  is relatively hot. The opposite is generally true when the bed is operated to provide heated air to an occupant. 
     Thus, when the bed assembly is being cooled, at least a portion of the conditioned air being delivered through the main fluid stream  2940  can be directed into an inlet of the pillow  2910  (e.g., through conduit branch  2944  and other downstream conduits  2960 ,  2962 ,  2962 ′). As shown in  FIG. 33 , the various conduits that are configured to deliver thermally-conditioned air to the pillow  2910  can be routed internally or externally to the mattress  2904  or other bed portion. Conveniently, when the bed is being heated, at least a portion of the waste fluid stream, which is relatively cold, can be directed to the pillow  2910 . For simplicity, the conduits that place the fluid module  2920  in fluid communication with the cooled pillow  2910  can be shared by the downstream lines of the main and waste fluid streams  2940 ,  2950 . A similar configuration can be used to provide heated and/or cooled air to one or more other portions of the bed (e.g., foot or leg region, main torso region, etc.), as desired or required. 
       FIG. 34  illustrates a schematic of one embodiment of a climate-conditioned bed  3010 . As shown, the bed  3010  can include an upper portion  3060  and a lower portion  3020 . Further, the bed  3010  can have a fluid distribution layer  3070  and a top member  3080 . The top member  3080  can be made of an air-permeable material. Moreover, as shown in  FIG. 34 , the bed  3010  can additionally include a second fluid distribution layer  3071 . According to certain embodiment, such a second fluid distribution layer  3071  comprises an underside layer  3081 . The second fluid distribution layer  3071  can also have a topside layer  3090 . The second fluid distribution layer  3071 , underside layer  3081  and topside layer  3090  can be configured to direct a flow of fluid, such as air, to an occupant. Further, the underside layer  3081  can have properties similar to the described top member  3080  of the various embodiments. For example, the underside layer  3081  can comprise one or more air-permeable material. As illustrated in  FIG. 34 , the top member  3080  can be configured to direct fluid toward an occupant&#39;s back when the occupant is in the supine position, whereas the underside layer  3081  can be configured to direct fluid toward the occupant&#39;s front. 
     The topside layer  3090  can be made of an air-impermeable material so that a fluid is not likely to escape through the topside layer  3090 . In other embodiments, the topside layer  3090  can generally provide more fluid flow resistance through the layer  3090  than the underside layer  3081 . Accordingly, the topside layer  3090  can encourage the flow of fluid through the underside layer  3081  rather than through itself. In some embodiments, the topside layer  3090 , the underside layer  3081  and/or the second fluid distribution layer  3071  cooperate to help maintain an occupant at a desired temperature. In one arrangement, the topside layer  3090  can act as an insulator that allows no or substantially no fluid flow to pass therethrough. 
     According to certain arrangements, in order to further enhance comfort, promote safety and/or offer additional advantages, one or more topper members or layers  3080  can be selectively positioned above the cushion member  3064  and the flow conditioning members  3070 . Similarly, one or more or underside members or layers  3081  can be positioned below the flow conditioning members  3071 . For example, in some embodiments, a lower topper layer can be configured to distribute air generally in a lateral direction, while an upper topper layer can be configured to distribute air in a vertical direction (e.g., toward an occupant). It will be appreciated, however, that more or fewer topper layers and/or underside layers can be included in a particular bed assembly. In addition, the topper layers and/or underside layers can be configured to distribute or otherwise flow condition air differently than discussed herein. For example, one or more of the layers can be configured to distribute air both vertically and laterally. 
     With continued reference to  FIG. 34 , the bed  3010  can include two independent sets of fluid transfer devices  3040  and thermoelectric devices  3050  serving each fluid distribution layer  3070 ,  3071  through conduits  3046 . According to some embodiments, one fluid module (e.g., a single fluid transfer device  3040  and its corresponding thermoelectric device  3050 ) generally serves the bed  3010 . In some embodiments, two or more fluid modules (e.g., fluid transfer devices, thermoelectric devices and/or other components) serve the fluid distribution layer or layers of the bed  3010 , as desired or required. 
     The depicted embodiment of a climate-conditioned bed  3010  can be configured to provide different levels of fluid conditioning to various areas of the bed. This can be accomplished, at least in part, by allowing users to selectively control the thermal conditioning effect (e.g., cooling, heating, ventilation, etc.) for each of the various established zones or regions in the bed. Further, the climate control system can be configured so that users are also able to selectively control the rate of fluid flow being directed to one or more regions of the bed  3010 . 
     As illustrated in  FIG. 35 , in some embodiments, one fluid distribution layer  70  can provide a conditioned fluid to both the front and back of an occupant.  FIG. 35  generally illustrates a bed  3110  having fluid distribution layers  3170  that could be characterized as wrap-around fluid distribution layers  3172 . The depicted arrangement shows a cross-sectional view of a bed  3110  with two wrap-around distribution layers  3172 . Such configurations can advantageously provide enhanced cooling and/or heating control to certain portions of the bed. For example, when two or more users share a bed, each user can customize a temperature-conditioning effect in accordance with his or her own preferences by directing conditioned and/or unconditioned fluid through only one of the wrap-around fluid distribution layers  3172 . 
     By providing cooling to both a front side and a back side of an occupant, a climate-conditioned bed can provide a multi-directional flow of fluid to better provide conditioned fluid to one or more occupants. In climate-conditioned beds comprising only one side that is configured to provide conditioned fluid, a temperature gradient can persist between an occupant&#39;s front side and back side, which may result in some level of discomfort. A wrap-around fluid conditioning layer or multiple fluid conditioning layers, as illustrated in  FIGS. 34 and 35  can alleviate such concerns. 
     In any of the embodiments illustrated herein, such as, for example, the climate controlled beds shown in  FIGS. 34 and 35 , the climate controlled bed can comprise legs or other support members to provide additional clearance between the bottom of the lower portion and the floor on which the bed is positioned. This can also help permit fluid inlets or other openings to be discretely positioned on a bottom surface of the lower portion. 
     With continued reference to  FIGS. 34 and 35 , in some embodiments stitching, barrier members (e.g., window border designs), glue beads, laminations and/or the like can be used to improve fluid flow through the flow conditioning members  3070 ,  3071 ,  3072  and  3170 ,  3171 ,  3172 . For example, engineered stitching can be provided along the perimeter and/or any other area to better control the flow of air or other fluid within the flow conditioning members. In some arrangements, the system uses particular stitching patterns, diameters, needle sizes, thread diameters and/or other features to control the flow of conditioned and/or unconditioned fluids therethrough. 
     Stitching or other flow blocking devices or features can also be used to control unwanted lateral flow of fluids. For example, stitches can be added around the perimeter of the device to prevent or substantially prevent fluid from moving outside one or more desired conditioned areas. The use of the proper stitching compression, patterns and/or other features can help provide a path for the fluid (e.g., air) to flow toward one or more occupants. The size of the stitching and the density of the stitches can be modified or otherwise controlled to provide even fluid distribution to an occupant. Thus, by using only a single sheet of spacer fabric and controlling the flow of fluid using stitching, lamination and/or other systems, a more cost effective upper portion  3060 ,  3160  or topper assembly can be realized. Accordingly, engineered stitching and/or other similar features can allow for improved fluid flow while enhancing the comfort level for an occupant. 
     As discussed in relation to other embodiments, herein, in order to accommodate for the vertical translation of a climate-controlled bed assembly, bellows, or other movable members can be used to provide the desired flexibility and/or insulation properties. It may be desirable to account for the movement of certain components of the bed and/or for the relative movement between adjacent bed components in order to protect fluid conduits, fluid transfer devices and/or other items that comprise the climate control system. 
     One important consideration associated with moving fluids within an air conditioned bed is accommodating fluid intakes and exhausts. Thus, in some embodiments of the devices and systems illustrated and disclosed herein, the fluid delivery system advantageously includes a relatively efficient means of receiving fluids from the surrounding environment and delivering them to the bed or other seating assembly. 
     For any of the embodiments disclosed herein, or equivalents thereof, climate control systems can be advantageously configured and/or controlled to reduce capital and/or operating (e.g., energy) costs. For example, the climate control system of a bed assembly can include fewer fluid modules (e.g., blowers, other air transfer devices, thermoelectric devices, etc.). Further, in some embodiments, the climate control system can be operated according to one or more control routines which are adapted to reduce energy consumption. In addition, such energy and cost saving measures can be implemented while maintaining or improving the performance of the climate controlled bed assembly. 
     The energy consumption of the control system can be reduced by advantageously controlling the operation of one or more of the blowers, thermoelectric devices and/or any other fluid modules or components thereof. For example, one or more thermoelectric devices can be turned on or off according to an energy-reducing control scheme. In other embodiments, the electrical current delivered to one or more thermoelectric devices is modulated to achieve a desired level of cooling and/or heating for the air passing therethrough. 
     In some embodiments, a blower or other air transfer device is configured to continuously operate as other components of the fluid modules (e.g., thermoelectric devices) are turned on/off or modulated. Alternatively, however, one or more of the fluid transfer devices can be configured to turn on or off during the operation of the climate control system. In other embodiments, the volume of air being delivered to the blower or other fluid transfer device can be varied by controlling the speed of the blower, by modulating one or more valves or by some other method. 
     In some embodiments, a desired operational sequence is configured to automatically begin and/or end based on the time of day, a timer (e.g., elapsed time from a particular event or occurrence) or the like. For example, the climate controlled bed assembly can be configured to provide a greater cooling or heating effect during the early part of a sleep cycle and gradually reduce such thermal effect as time elapses. In other embodiments, a user can selectively customize the bed to operate according to a desired scheme. In still other configurations, a particular operational scheme can be activated and/or deactivated using feedback received from one or more sensors. For example, a temperature sensor, humidity sensor, motion sensor, pressure sensor, another type of occupant-detection sensor or the like can be used to detect the presence of an individual on or near the climate controlled bed assembly. Thus, such assemblies can be configured to function in a desired manner when a user triggers a sensor or other activation device. 
     Moreover, a climate controlled bed can be configured to function under two or more operational modes. For example, a climate controlled bed can permit one or more of its occupants to select a level of cooling and/or heating (e.g., “Low-Medium-High”, “1-2-3-4-5”, etc.). Alternatively, beds can be configured with climate control systems that allow users to enter an actual temperature setting. In other embodiments, users can select a desired setting, temperature and/or other operational mode using a knob, lever, switch, keypad or the like (e.g., the control devices illustrated in, inter alia,  FIGS. 5, 18A-18E and 31 ). In still other arrangements, users are permitted to program an operational scheme for a climate controlled bed assembly that satisfies their unique preferences and/or requirements. 
     As discussed, control of the fluid modules and/or any other components of the climate control system can be based, at least partially, on feedback received from one or more sensors. For example, a climate controlled bed can include one or more thermal sensors, humidity sensors, optical sensors, motion sensors, audible sensors, pressure sensors and/or the like. In some embodiments, such sensors can be positioned on or near a surface of the climate controlled bed to determine whether cooling and/or heating of the assembly is required or desired. For instance, thermal sensors can help determine if the temperature at a surface of the bed assembly is above or below a desired level. Alternatively, one or more thermal sensors and/or humidity sensors can be positioned in or near a fluid module, a fluid conduit (e.g., fluid passageway) and/or a layer of the upper portion of the bed (e.g., fluid distribution member, comfort layer, etc.) to detect the temperature and/or humidity of the discharged fluid. Likewise, pressure sensors can be configured to detect when a user has been in contact with a surface of the bed for a prolonged time period. Depending on their type, sensors can contact a portion of the bed assembly. As discussed, in some embodiments, sensors are located within and/or on the surface of the bed assembly. However, in other arrangements, the sensors are configured so they do not contact any portion of the bed at all. Such operational schemes can help conserve power, enhance comfort and provide other advantages.
