     STATEMENT OF GOVERNMENT INTEREST 
     None. 
     BACKGROUND OF THE DISCLOSURE 
     Field of the Disclosure 
     The disclosure generally relates to a mattress thermal management system, in particular incorporating an airflow spacer and/or a suction- and/or discharge-based cooling and/or heating system. Deck-mounted fans beneath a mattress operate in various embodiments to induce a uniform suction flow, a uniform discharge flow, and/or a combined suction/discharge (circulating) flow that enhances the cooling and/or heating rate of the mattress. The mattress thermal management system can be incorporated into a conventional mattress/bed system or into an adjustable bed system. Further, the mattress thermal management system including an airflow spacer can be incorporated into a cover for a conventional mattress foundation or adjustable bed foundation. In another aspect, the disclosure relates to a remote control that controls an adjustable bed and is configured with a children&#39;s safety lock feature. 
     SUMMARY 
     In an aspect, the disclosure relates to a mattress support structure comprising: a mattress support having a top surface for supporting a mattress and an opposing bottom surface; and an airflow spacer positioned above the top surface of the mattress support, the airflow spacer (i) having a thickness of at least 1 mm or at least 5 mm (e.g., at least 1, 2, 5, 10, 15, or 25 mm and/or up to 5, 7, 10, 15, 25, 50, 75, 100, 150, 250, or 300 mm thick, such as generally measured in a direction normal to the mattress support (top) surface) and (ii) being adapted to permit airflow therethrough; wherein the mattress support structure is free from fans mounted thereto. The airflow spacer can be adapted to permit airflow therethrough based on an open volume in the airflow spacer such as in a three-dimensional fabric. Airflow can be to/from the edge/periphery of the airflow spacer and to/from the external/ambient environment, to/from the top surface of the airflow spacer and to/from the bottom surface of the mattress when present, and/or to/from the bottom surface of the airflow spacer and to/from the mattress support when it includes air flow channels or other open areas permitting air flow therethrough. In various embodiments, the airflow spacer or multiple airflow spacers are the sole or only cooling or thermal management components to the mattress support structure or corresponding bed/mattress assembly. The mattress support structure or corresponding bed/mattress assembly can be free from other heating and/or cooling elements, whether based on convective and/or conductive heating and/or cooling. It has been found that the presence of the airflow spacer can allow sufficient cooling effect due to conduction and natural convection effects with the ambient environment to the mattress support/bed (e.g., without necessarily including active heating or cooling elements). 
     In another aspect, the disclosure relates to a mattress support structure comprising: a mattress support having a top surface for supporting a mattress and an opposing bottom surface; a mattress support cover adapted to cover at least the top surface of the mattress support; and an airflow spacer positioned above the top surface of the mattress support, the airflow spacer (i) having a thickness of at least 1 mm or at least 5 mm (e.g., at least 1, 2, 5, 10, 15, or 25 mm and/or up to 10, 15, 25, 50, 75, 100, 150, 250, or 300 mm thick, such as generally measured in a direction normal to the mattress support (top) surface), (ii) being adapted to permit airflow therethrough, and (iii) being an integral component of the mattress support cover.

     DETAILED DESCRIPTION 
     The disclosure generally relates to a mattress thermal management system, for example a mattress cooling system and in particular a suction-based cooling system. In other embodiments, the mattress thermal management system can operate as a mattress heating system. Deck-mounted fans beneath a mattress operate in various embodiments to induce a uniform suction flow or a combined suction/discharge (circulating) flow that enhances the cooling or heating rate of the mattress. Suitably, air is used as the fluid heat transfer medium, whether the system is operating for mattress cooling or heating. In other embodiments, a gaseous fluid other than air may be used as a fluid heat transfer medium circulated by the deck-mounted fans (e.g., alone or in combination with air). Accordingly, references in the following description to “air” and “airflow” apply as well to various other gaseous heat transfer fluids more generally. The mattress cooling system can be incorporated into a conventional mattress/bed system or into an adjustable bed system. In other embodiments, the mattress cooling system can be comprised solely of an airflow spacer with a minimum thickness of 1 mm or 5 mm positioned intermediate a mattress support structure and a mattress, the airflow spacer adapted to permit significant airflow therethrough. In other embodiments, the mattress cooling system can be comprised of a mattress support structure incorporating an airflow spacer with a minimum thickness of 1 mm or 5 mm, the airflow spacer adapted to permit significant airflow therethrough and a mattress positioned above the mattress support of the mattress support structure. In other embodiments, the mattress cooling system can be comprised of a cover for a mattress support structure having a top surface and an opposing bottom surface and incorporating an airflow spacer with a minimum thickness of 1 mm or 5 mm between the top surface and the bottom surface, the airflow spacer adapted to permit significant airflow therethrough. 
       FIG. 1  is a side exploded view of a mattress thermal management (e.g., cooling and/or heating) system  10  according to the disclosure. The illustrated mattress thermal management system  10  includes a mattress deck (or mattress support)  100 , optionally an airflow spacer  200  positioned thereon, and a mattress  300  positioned above the mattress deck  100  (e.g., sitting upon the airflow spacer  200  when present or sitting directly on the mattress deck  100 ).  FIG. 2  is a top perspective illustration of the mattress  300  according to a particular embodiment of the disclosure. More generally, the mattress thermal management system  10  and components thereof can be used with a fixed-frame bed or an adjustable-frame bed. 
     The mattress deck  100  includes a deck support platform  110 , for example including a plurality of deck support platforms  110 A- 110 D as illustrated. A single unitary deck support platform  110  is suitable for a conventional (non-adjustable) bed assembly. A deck support platform  110  formed from a plurality of deck support platforms  110 A- 110 D is suitable for an adjustable bed assembly. In some embodiments the support platform(s)  110  can be formed from a rigid support material such as wood or metal. In other embodiments the support platform(s) can be formed from a flexible fabric or material. The deck support platform  110  includes a fan  120  (e.g., axial fan, centrifugal fan, cross-flow fan, or other means for blowing or otherwise transporting air or gaseous fluid) mounted thereto, for example plurality of fans  120 A- 120 D as illustrated. While each deck support platform  110 A- 110 D is illustrated as having a corresponding fan  120 A- 120 D, each platform  110 A- 110 D can have none, one, or more than one corresponding fans  120  mounted thereto. Each fan  120  is mounted to the deck  110  adjacent to, within, or otherwise in fluid communication with a corresponding airflow channel  130 , thereby permitting airflow through the mattress  300 , the airflow spacer  200  (when present), and the mattress deck (i.e., via the airflow channel  130  and the fan  120 ) in either direction. 
     Each fan  120  has a suction side  122  (i.e., a fan surface/plane across which air is drawn from the external environment into the fan interior) and a discharge side  124  (i.e., a fan surface/plane across which air is expelled from the fan interior to the external environment). As illustrated, the fan  120  can be mounted on its suction side  122  to the deck support platform  110 , thereby creating a suction air flow during fan operation, drawing air through the mattress  300  and expelling the air beneath the deck support platform  110  to the external environment underneath the bed. As alternatively illustrated, the fan  120  can be mounted on its discharge side  124  to the deck support platform  110 , thereby creating a discharge air flow during fan operation, drawing air from the external environment underneath the bed, through the deck support platform  110  and then through the mattress  300 . In some embodiments, the fans  120 A- 120 D are all mounted in the same suction/discharge orientation (e.g., all mounted on their suction sides  122  to the platform  110 ; all mounted on their discharge sides  124  to the platform  110 ). In other embodiments, the fans  120 A- 120 D are mounted in a mixed suction/discharge orientation (e.g., some mounted on their suction sides  122  to the platform  110  and some mounted on their discharge sides  124  to the platform  110 ). In some embodiments, some or all of the fans  120 A- 120 D are unidirectional fans (i.e., having fixed suction and discharge sides, being intended to transport air in a single direction). In some embodiments, some or all of the fans  120 A- 120 D are bidirectional fans (i.e., having variable suction and discharge sides depending on impeller rotation, being capable of transporting air in two different (opposing) directions). 
     The airflow spacer  200  can be any type of structure that includes an open void volume permitting airflow therethrough and directing the airflow to improve the spatial distribution (e.g., uniformity thereof) of airflow through the mattress  300  (e.g., in particular when the fans  120 A- 120 D are positioned at discrete, non-uniformly spaced locations in the deck support platform  110 ). Suitably, the airflow spacer  200  is a formed from a flexible material to accommodate a moveable deck support platform  110  of an adjustable bed. Suitable structure for the airflow spacer  200  includes a mesh fabric (e.g., three-dimensional fabric) or other porous material, a manifold structure, a duct structure, a channel structure, and a cavity structure. In some embodiments, the airflow spacer  200  is a separate structure from the mattress  300  and the mattress deck  100 . In other embodiments, the airflow spacer  200  can be an integral component of the mattress deck  100  (e.g., with the platform(s)  110  thereof) or it can be an integral component of the mattress  300  (e.g., with the base  310  thereof). 
     The mattress  300  is not particularly limited, and it can be a conventional mattress  300  (e.g., a spring or coil mattress, memory foam mattress, air mattress) with a base  310  (e.g., a continuous fabric material) suitable for use on a mattress support structure such as a fixed bed frame or an adjustable bed frame. In the illustrated embodiment, the mattress  300  includes a mattress containment frame  305  including a plurality of foam cells (or foam springs)  340  positioned in the frame  305  to provide the sleeping support surface for the mattress. The mattress containment frame  305  includes a lower/bottom base  310 , sidewalls  320 , and endwalls  330  which generally define the interior frame  305  volume housing the foam cells  340 . The sidewalls  320  and endwalls  330  suitably are formed from a foam material. The base  310  can be a generally continuous fabric material (e.g., a continuous surface but sufficiently thin and porous at a small scale to permit airflow therethrough between the mattress  300  and the airflow spacer  200 , such as a fabric material). In some embodiments, the base  310  can include one or more larger open areas (e.g., airflow channels) to enhance the rate of airflow therethrough between the mattress  300  and the airflow spacer  200 . The mattress  300  and optionally the airflow spacer  200  (e.g., as a separate or integral component of the mattress  300 ) are generally positioned above the mattress support  100 , for example sitting directly atop the deck support sections  110 A- 110 D. 
       FIGS. 3 a  and 3 b    illustrate a bottom view of a mattress deck  100  and an associated adjustable bed frame  400  according to the disclosure ( 3   a : twin deck and bed frame;  3   b : queen deck and bed frame). The adjustable frame  400  generally provides the mechanical, electrical, and electronic support and articulation components for the mattress system  10  and mattress deck  100 . As illustrated, the adjustable frame  400  includes a frame support  410 . Each deck support section  110 A- 110 D can be fixedly or removably mounted (e.g., via bolts, screws, or other fastener or adhesive components) to the underlying frame support  410  such that when one or more sections of the frame support section  410  are articulated, the deck support sections  110 A- 110 D are correspondingly articulated. As illustrated, the adjustable frame  400  further includes a subframe  430 , for example a rigid, non-articulatable frame structure which sits on a floor or within a decorative bed frame common in the furniture industry such as a platform bed (e.g., via various leg elements, not shown) and provides stability for the mattress system  10  as the adjustable frame  400  is articulated to various different positions. The adjustable frame  400  can further include one or more support members  420  connecting structure between the subframe  430  and the frame support  410 . As further illustrated, the adjustable frame  400  can include one or more actuators  440  variously mounted to one or more of the subframe  430 , a support member  420 , and the frame support  410 . In some embodiments, the subframe  430 , the support members  420 , and the frame support  410  can be formed from metal such as steel. The actuators  440  can be any of those commonly known in the art. The actuators  440  and, correspondingly, the configuration or position of the adjustable frame  400 , mattress support  100 , and mattress  300  can be controlled and adjusted by a suitable power supply  450 , adjustable bed controller  450  (e.g., programmable logic controller or otherwise, which may be integrated with the power supply or separate structure), and a remote control  460  to deliver repositioning commands and/or thermal management system commands (e.g., fans/system on or off; fans/system in heating or cooling mode; fan/system intensity/speed). In some embodiments, a programmable timer may be incorporated into the adjustable bed controller  450 , the remote control  460 , or otherwise, thus allowing the fans  120  to be programmably operated in any desired heating and/or cooling mode at a user-specified fan intensity/speed, temperature set point, start time, a user-specified duration, and/or a user-specified end time. 
     In some embodiments, the controller  450  is a combined controller providing power and send/receive command/control functionality to both the adjustable bed frame  400  (e.g., repositioning commands, power to actuators  440 , etc.) and the thermal management system  10  (e.g., thermal management commands, power to fans  120 , etc.). In other embodiments, the controller  450  can include two separate controller structures: a first controller providing power and send/receive command/control functionality to the adjustable bed frame  400  and a second controller providing power and send/receive command/control functionality to the thermal management system  10 . In such embodiments, the first and second controllers can be electronically connected (e.g., wired or wireless connection), for example in a master-slave arrangement. For example, the first controller can be a master controller capable of receiving commands from the remote  460  for both the adjustable bed frame  400  and the thermal management system  10 , and then the first controller can pass commands for the thermal management system  10  to the second controller for execution. In other embodiments, each of the first and second controllers may be configured to independently receive and execute commands from the remote  460 . 
     The remote control  460  is not particularly limited. In an embodiment, the remote  460  includes a touch screen  462  to receive user commands (e.g., regarding adjustable bed position, fan operation, heating/cooling modes, timing of same, etc.) and/or to display to the user the current status of the adjustable bed position and/or the thermal management system (e.g., reflecting confirmation of successfully executed commands as sensed and reported by the controller  450 ). In some embodiments, the remote  460  can be a wired unit connected to the controller  450 , for example a dedicated remote  460  for the adjustable bed. In other embodiments, the remote  460  can include a wireless transceiver for communication (e.g., two-way communication) with a corresponding transceiver in the controller  450 . Any suitable wireless communication protocol may be used to send commands from the remote  460  to the controller  450  (e.g., and optionally to receive feedback from the  450  confirming successful execution of the sent commands), for example including infrared (IR) and/or radio frequency (RF) (e.g., WIFI, BLUETOOTH, or otherwise) wireless protocols. In some embodiments, the wireless remote  460  can be communication matched with the controller  450 , for example using a communication key or code key transmitted and received between the remote  460  and controller  450  to confirm that the controller  450  may receive and execute user commands from the remote  460  (e.g., further including a confirmation from the controller  450  to the remote  460  that the communication key or code key has been received and accepted). The wireless remote  460  can be a dedicated remote  460  for the adjustable bed. In other embodiments, the wireless remote  460  can be a mobile electronic device (e.g., cell phone, smart phone, tablet computer) running a software application providing a user interface for control of adjustable bed functions and/or thermal management system functions. The remote  460  also can implement various memory functions associated with the adjustable bed and/or thermal management system, for example using memory-stored settings related to the same in one or more of the remote  460 , the controller  450 , and a location separate from the remote  460  and the controller  450  (e.g., at a remote network location). Memory settings related to adjustable bed position, thermal management settings (e.g., fan speed, duration, start/stop time, temperature set point), or both can be stored in memory (e.g., based on a user indication to save one or more settings as presets for later recall) using the remote  460 , and the memory settings can be recalled at a later time by the remote  460  as command for execution by the controller  450 . In some embodiments, the memory setting can relate to a single setting (e.g., an adjustable bed position, a thermal management setting). In other embodiments, the memory setting can represent a global command relating to multiple settings (e.g., one or more adjustable bed positions for multiple bed segments, one or more thermal management settings, combinations thereof, etc.). 
     The thermal mattress system  10  can further include one or more temperature sensors  160  (e.g., a thermocouple or other suitable conventional means for sensing temperature). The sensor(s)  160  can be located at any desired location(s) in the mattress system, for example on the mattress deck  100 , the airflow spacer  200 , the mattress  300 , and/or the adjustable bed frame  400 . For example, the sensors(s) can be located on a fan  120  surface (e.g., as illustrated; such as on or near an intake or exhaust surface), a deck support  110  surface (e.g., bottom or top side thereof), an interior or exterior surface of the airflow spacer  200 , an interior or exterior surface of the mattress  300  or a component thereof (e.g., base  310 , sidewall  320 , endwall  330 , foam cylinder  340 , top or bottom surface of mattress  300  as a whole). The temperature sensor(s)  160  can be coupled to the controller  450  (e.g., a component thereof for the thermal management system  10 ) for form a temperature feedback control loop for the thermal management system  10 . Given a temperature set point (e.g., preset or selected by a user), the controller  450  can be programmed to monitor current temperature and adjust the thermal management system  10  settings based on the set point (e.g., increase or decrease heating or cooling such as by adjusting fan intensity/speed, fan operation duration, heating/cooling unit output temperature). In some embodiments, a user can enter a desired set point in terms of a user-sensible temperature (e.g., mattress upper surface temperature, ambient temperature above the mattress upper surface), and the controller  450  feedback control loop logic can be programmed to use the temperature actually sensed at a different location by the sensor  160  as a proxy for the set point (e.g., by specifying or determining a relationship between the desired set point and the sensed temperature). 
     As shown, the fans  120  may be irregularly spaced/positioned on the underside of the mattress deck  100  to accommodate other mechanical and/or electronic bed components, in particular for the adjustable bed frame  200 . The fans  120  can be powered and controlled by the electromechanical system of the adjustable bed (e.g., illustrated via the wires from fans to the power supply/programmable logic controller  450  (PLC), which can provide power to the fans  120  and can provide operating instructions to the fans  120 , for example as received from an external remote control unit  460  for the adjustable bed).  FIG. 4 a    is a schematic of the bottom side of the mattress deck  100  of  FIG. 3 b    showing the placement of four cooling fans  120  as well as optional placement locations  120 ′ for additional fans (e.g., if greater airflow is desired).  FIG. 4 b    is is a schematic of the bottom side of the mattress deck  100  in alternative embodiment including one fan  120  in the head section  110 A and one fan  120  in the foot section  110 B of the mattress deck  100 . 
       FIG. 5  is a side view of mattress cooling system embodiments according to the disclosure (A: mattress-side airflow discharge; B: mattress-side airflow suction; C: mattress-side airflow combined discharge and suction). In  FIG. 5A , both fans  120  are mounted (or otherwise operating in) a mattress-side discharge orientation in which airflow is transported from beneath the deck support platform  110  and up through the mattress  300 . In  FIG. 5B , both fans  120  are mounted (or otherwise operating in) a mattress-side suction orientation in which airflow is transported from above the mattress  300 , through the mattress  300  and the deck support platform  110 , and to the area beneath the deck support platform  110 . In  FIG. 5C , the fans  120  are alternatively mounted (or otherwise operating in) in a mattress-side suction orientation and a mattress-side discharge orientation, thereby creating a recirculating airflow pattern for enhanced cooling effectiveness. In any of the of the various fan  120  configurations and operating modes (e.g., mattress-side suction, discharge, or recirculation flow), the operation of the fans and be used to actively cool the mattress  300  with ambient environmental air, for example from either above the mattress  300 , below the mattress deck  100 , or both. 
     Other cooling embodiments for cooling the mattress  300  of the mattress system  10  are possible. For example, in the embodiments illustrated in  FIGS. 5A and 5C , a cooler or cooling unit  150  may be positioned below the mattress deck  100  (e.g., mounted thereto and/or to mattress support structure therebelow such as the adjustable bed frame  400  or a component thereof), and the cooler  150  can be positioned to cool air  152  being fed upwards into the mattress  300  (e.g., by either fan  120  illustrated in  FIG. 5A ; by the left-illustrated fan  120  in  FIG. 5C ), thus actively cooling the mattress  300 . In an embodiment, the cooler  150  can be a portable cooling or air conditioning unit  150  capable of cooled air relative to the ambient environment. Alternatively, the cooler  150  may be positioned remotely from the mattress deck  100  (or bed more generally) and the cooler  150  can direct cold air  152  from the remote location to the fans  120  for circulation through the mattress  300 . The remote cooler  150  can be a portable cooling or air conditioning unit  150  spaced proximately to direct cold air  152  below the mattress deck  100  to be fed upwards into the mattress  300 . In some embodiments, the remote cooler  150  can be an HVAC (heating, ventilation, air conditioning) system or a component thereof, such as a home HVAC system configured to direct cold air  152  below the mattress deck  100  to be fed upwards into the mattress  300 . In embodiments including a cooler  150 , the mattress system  10  may be independently operated at the discretion of the user in a cooling mode using ambient environmental air (e.g., as described above without the cooler  150  being active) or a cooling mode using the cold air  152  from the cooler  150  to cool the mattress  300 . 
     In some embodiments, the mattress system  10  can be adapted to heating the mattress  300  instead of cooling. For example, in the embodiments illustrated in  FIGS. 5A and 5C , a heater or heating unit  140  may be positioned below the mattress deck  100  (e.g., mounted thereto and/or to mattress support structure therebelow such as the adjustable bed frame  400  or a component thereof), and the heater  140  can be positioned to heat air  142  being fed upwards into the mattress  300  (e.g., by either fan  120  illustrated in  FIG. 5A ; by the left-illustrated fan  120  in  FIG. 5C ), thus actively heating the mattress  300 . In an embodiment, the heater  140  can be a portable heating unit  140  such as an electrically powered semiconductor-based micro thermal module capable of providing radiant heat relative to the ambient environment. Alternatively, the heater  140  may be positioned remotely from the mattress deck  100  (or bed more generally) and the heater  140  can direct hot air  142  from the remote location to the fans  120  for circulation through the mattress  300 . The remote heater  140  can be a portable heating unit  140  spaced proximately to direct hot air  142  below the mattress deck  100  to be fed upwards into the mattress  300 . In some embodiments, the remote heater  140  can be an HVAC system or a component thereof (e.g., where the same HVAC system is capable of providing cool air for cooling as above or hot air for heating), such as a home HVAC system configured to direct hot air  142  below the mattress deck  100  to be fed upwards into the mattress  300 . In embodiments including a heater  140 , the mattress system  10  may be independently operated at the discretion of the user in either a cooling mode (e.g., as described above without the heater  140  being active) or in a heating mode (e.g., with the heater  140  actively supplying heat to the airflow entering the mattress  300 ). 
       FIG. 6  is a top perspective illustration of a mattress containment frame  305  according to the disclosure, and  FIG. 7  is a side cut-away view of the mattress containment frame  305  and a corresponding airflow spacer  200  according to the disclosure. In an embodiment, the base  310  of the frame  305  can include a plurality of locator recesses  312  that are size and shaped (e.g., cylindrical as shown) to accommodate and seat corresponding foam cells  340 . Each locator recess  312  includes a locator pin (or protrusion)  314  that mates with the corresponding open cylindrical channel  342  of a foam cell  340 . The locator pin  314  has an open top area  318  to permit airflow through the open cylindrical channel of the foam cell  340 , through the open top area of the locator pin  314 , and then into the airflow spacer  200 . As further illustrated, the base  310  includes a plurality of vent holes  316  positioned to permit airflow through the interstitial areas between adjacent foam cells  340  and the airflow spacer  200 . The locator pin  314  open areas and vent holes  316  permit air circulation within the mattress  300 , thereby enhancing the cooling effect of the fans  120 . In the illustrated embodiment of  FIG. 7 , the airflow spacer  200  has an open channel-type structure and it further includes an open airflow channel area (or hole)  230  that generally corresponds to a similarly positioned airflow channel  130  in the deck support platform  110 . In other mattress embodiments, airflow channels/structures through the thickness of the mattress  300  can be incorporated into a conventional mattress  300  as desired, thereby providing an airflow path for cooling and/or heating airflow paths between the top and bottom of the mattress  300  (e.g., similar to those provided by the vent holes  316  and open areas  318  in the illustrated embodiment), for example also in fluid communication with the open airflow channel area (or hole)  230  (e.g., in the bottom of the airflow spacer  200 ) and the airflow channel  130  in the mattress deck support  110 . 
       FIGS. 1A and 1B  illustrate further embodiments of the mattress thermal management system  10  according to the disclosure which include the airflow spacer  200 , and which can either include or omit the deck-mounted fans  120  described herein.

In a refinement, the airflow spacer  200  can be any type of structure that includes an open void volume permitting significant airflow therethrough and permitting the improvement of the spatial distribution (e.g., uniformity thereof) of airflow. Suitably, the airflow spacer  200  is a formed from a flexible material to accommodate a moveable deck support platform of an adjustable bed. Suitable structure includes a mesh fabric (e.g., three-dimensional fabric) or other porous material, a manifold structure, a duct structure, a channel structure, and a cavity structure.

Suitable structure includes a mesh fabric (e.g., three-dimensional fabric) or other porous material, a manifold structure, a duct structure, a channel structure, and a cavity structure. 
     In another embodiment, the mattress thermal management system  10  comprises of a cover  210  for a mattress support structure  100  (e.g., bed frame) with the cover  210  having a top surface  210 A and an opposing bottom surface  210 B. In a refinement, the cover  210  for a mattress support comprises an airflow spacer  200  with a minimum thickness of 1 mm or 5 mm that can be any type of structure that includes an open void volume permitting significant airflow therethrough and permitting the improvement of the spatial distribution (e.g., uniformity thereof) of airflow. Suitably, the cover  210  and/or airflow spacer  200  is a formed from a flexible material to accommodate a moveable deck support platform of an adjustable bed. Suitable structure includes a mesh fabric (e.g., three-dimensional fabric) or other porous material, a manifold structure, a duct structure, a channel structure, and a cavity structure. In some embodiments, the cover  210  is designed to cover only the top surface of a mattress support structure  100 . In other embodiments, the cover is designed to cover the entire mattress support structure  100 . 
     In another aspect, the disclosure relates to a remote control that controls an adjustable bed and is configured with a children&#39;s safety lock feature, for example as illustrated in  FIG. 8 . 
     Adjustable beds are able to articulate in many different fashions and angles. As a result, the possibility exists that if an unsupervised child accidentally activates the adjustable bed using the bed&#39;s remote control, the child may suffer an injury from the resulting articulation of the bed. Therefore, the need exists for an adjustable bed&#39;s remote control to include a children&#39;s safety lock feature that makes the remote inoperable unless a specific action that is defined by the remote control is taken in order to deactivate the safety lock feature, unlocking the remote and making it operable. However, implementing such a feature on a device with a small footprint such as remote control is difficult and such features can be prone to accidental deactivation. Therefore, the need exists to design a remote control with an innovative safety lock feature that is difficult for a child to deactivate. 
     In one embodiment of the disclosure, a remote control  460  for an adjustable bed is designed such that two or more buttons  464 A,  464 B of the remote control&#39;s general set of buttons  464  are configured such that they are minimally spaced by a distance D of at least one inch or one and one half centimeters (e.g., at least about 25 mm or at least about 15 mm) from each other. The remote control  460  is designed such that it incorporates a children&#39;s safety lock feature that makes the remote  460  inoperable unless a certain action that is defined by the remote control&#39;s software is performed. Such action is defined by the remote control&#39;s software as pressing at the same time two or more of the buttons  464 A,  464 B that are minimally spaced by at least one inch or one and one half centimeters (e.g., at least about 25 mm or at least about 15 mm) from each other. After the remote control  460  is unlocked, the remote  460  will once again become inoperable after a specific time period of inactivity, as defined in the remote control&#39;s software or by once again pressing at the same time the two or more buttons  464 A,  464 B that are minimally spaced by at least one inch or one and one half centimeters (e.g., at least about 25 mm or at least about 15 mm) from each other.

Nos. 7,321,811, 7,465,280, 7,805,785, 7,930,783, 7,933,669, 7,979,169, 8,019,486, 8,032,263, 8,032,960, 8,046,114, 8,046,115, 8,046,116, 8,046,117, 8,050,805, 8,069,512, 8,078,336, 8,078,337, 8,150,562, 8,375,488, 8,565,934, 8,682,457, and 9,474,384 are incorporated herein by reference in their entireties and variously disclose mattresses including foam springs or foam cells and materials/configurations therefor, adjustable bed assemblies including adjustable mattress frames, electrical, mechanical, and electronic components associated therewith, and remote controls for use therewith, all of which may be used individually or collectively in combination with the mattress cooling system described herein. 
     Examples 
     The following examples illustrate the disclosed apparatus and methods, but they are not intended to limit the scope of any claims thereto. 
     The queen bed illustrated in  FIG. 3 b    and  FIG. 4 a    was tested for its ability to cool a heated mattress, including a conventional mattress and a foam cell mattress as illustrated in  FIG. 2 . An electrical heating pad was used to heat the mattress for a fixed period (about 15 minutes), then the heating pad was removed, and then the mattress was allowed to cool with the fans operating to enhance cooling. The fans, which were operating in a mattress-side suction orientation (e.g., as illustrated in  FIG. 5B ), were effective at cooling the mattress and returning it to an ambient environmental temperature over a period of about 4 to 8 minutes. 
     Because other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the disclosure is not considered limited to the example chosen for purposes of illustration, and covers all changes and modifications which do not constitute departures from the true spirit and scope of this disclosure. 
     Accordingly, the foregoing description is given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications within the scope of the disclosure may be apparent to those having ordinary skill in the art. 
     All patents, patent applications, government publications, government regulations, and literature references cited in this specification are hereby incorporated herein by reference in their entirety. In case of conflict, the present description, including definitions, will control. 
     Throughout the specification, where the compositions, processes, or apparatus are described as including components, steps, or materials, it is contemplated that the compositions, processes, or apparatus can also comprise, consist essentially of, or consist of, any combination of the recited components or materials, unless described otherwise. Component concentrations can be expressed in terms of weight concentrations, unless specifically indicated otherwise.
