   Background—Field of the Invention 
   The present invention relates to serving trays, and more particularly to a serving tray having an elongated configuration with a smooth upper surface, opposing end panels each having a sturdy handle means, a perimeter rim with a minimum height dimension of approximately one inch extending between the end panels and contiguous therewith, a removable high-friction mat capable of being rolled up into a compact cylindrical storage configuration when not needed for use, and a yielding bottom portion containing inert, non-toxic, non-allergenic, and lightweight soft fill material that conforms to the configuration of the surface or lap upon which it is placed. Optionally, the tray may also have a perimeter groove on one or more of its sides for food crumbs and/or placement of the high-friction mat when it is rolled into its compact storage configuration. Further options include a detachable self-contained bottom portion, and one or more recessed areas in the smooth upper surface for holding objects that contain easily spilled foods or beverages, such as but not limited to a glass, can, bottle, mug, or cup for a beverage or soup. Also, the mat may have thermal properties or a mesh configuration that protects the smooth upper tray surface from heat damage and/or helps to maintain elevated or reduced temperatures of pre-heated and pre-chilled food during its transport to the person intended to consume it. 
   Background—Description of Related Art 
   Trays are known for use in transporting food to the place where it will be served or eaten. One example is a bed tray with legs that collapse for storage, for serving food to invalids and others. However, when such trays are made from wood and have several containers filled with food or beverage supported on its upper surface, they can be heavy to transport. Further, during transport, supported containers often shift position on the upper surface of traditional serving trays, making spill-free transport awkward and difficult. In addition, when a tray with collapsible legs is presented to a person in bed, its height dimension is often too high or too low for the person using it, as well as too heavy to be supported directly upon the user&#39;s lap. Further, during eating use, food crumbs are nearly always created and spread over the food containers and tray surface, particularly when breads are a part of the meal served on the tray. Although not creating any hazard, the crumbs can be unsightly and detract from the dining experience. Another disadvantage of food served on a tray, is that it by the time it reaches the consumer, food that once was hot and very appealing has often cooled sufficiently to no longer present a strong appetite stimulus, something that can be important to a bedridden person or one that is recovering from an illness. In response to these deficiencies, the present invention provides a serving tray having a perimeter rim that helps to retain items on its surface during transport, as well as during use by those having weakened conditions and impaired sight, yet the rim is sufficiently low so as not to hinder use of the tray by the person dining from it. Further, the present invention serving tray has a sturdily constructed handle means that assists in confident and controlled tray transport. Ease in tray manipulation through sturdy and easily gripped handles reduces spillage during transport and assists in positioning the tray in an upright, or slightly tilted position if preferred, on the lap of its user. Further, use of a high-friction mat on the upper tray surface helps to prevent food containers from shifting position during transport, and while dining takes place by those having weakened physical states and diminished eyesight. The smooth upper tray surface facilitates adhesion of the high-friction mat. It is also contemplated for the mat to be removable for cleaning, or when the person using it prefers dining without it, such as to view a picture or other design on the upper tray surface, and although not critical it is preferred that the mat substantially cover the entire upper tray surface. When not in use, the high-friction mat should be able to be conveniently rolled up into a compact cylindrical storage configuration. For aesthetics, reduced cost, and/or practicality, a high-friction mat having a reduced size relative to the upper tray surface can be used as desired or needed. Further, the high-friction mat can optionally have thermal properties or a mesh configuration that help to protect the tray surface from heated tableware, protect it from spills involving high temperature foods, and/or assist in maintaining the original elevated or chilled temperature of some foods transported thereon. The tray and high-friction mat can also have one or more recesses or receptacles each configured to accommodate a glass, can, cup, mug, bottle, or other container for beverages, soup, and/or easily spilled foods. Corresponding recesses and receptacles that are to be combined for use in supporting a container for beverage or food would have a substantially similar size and be in substantially the same location relative to the upper tray surface. Optionally, instead of a receptacle, the high-friction mat can have a cutout through which a glass, can, cup, mug, bottle, or other container may be inserted into a recess. Further, the yielding bottom portion of the present invention is filled with an inert, non-toxic, non-allergenic, and lightweight soft fill material, that can be granular or filamentous, or a combination thereof, and which allows it to comfortably conform to the configuration of the surface or lap upon which it is placed. Optionally, the bottom portion can be self-contained and detachable through the use of quick-release fasteners, such as but not limited to a hook-and-pile type of fastener. The material or fabric from which the yielding bottom portion is made is preferably soft and washable. Should mechanical laundering be desired, it is contemplated that the fill material and/or insert containing fill material could be removed via a quick closure means, such as but not limited to a zipper that is in an out-of-the-way location and substantially hidden from view. Detachability permits exchange of one bottom portion for another and provides a bedridden person with new visual stimulus at a reduced cost. When not detachable, the bottom portion can be connected to the serving tray member by a variety of means, such as but not limited to decorative tacks, adhesive means, and/or bonding agent. The perimeter groove into which a person dining from the tray can temporarily sweep aside crumbs and other food residues created during the dining process, can enhance the user&#39;s dining experience by allowing that person to have control over the desired level of cleanliness and/or visible clutter on the upper tray surface. The: perimeter groove can also be used as a place in which to store the rolled-up high-friction mat when its use is not needed or desired. 
   The inventions thought to be the closest to the present invention are those disclosed in U.S. Pat. No. 4,052,944 to Jennings (1977) and U.S. Pat. No. 4,788,916 to Saxton (1988). However, there are important differences between the present invention and these other inventions. The Jennings invention discloses a portable desk with a hard desk surface, a partially rigid sub-cover that is coplanar with the hard desk surface, and a flexible casing means that is pillow-like and filled with dry, flowable material, such as sawdust, styrofoam beads or particles, and polyurethane beads or granules. After the edges of the casing are inturned over the sub-cover to form a container for the flowable fill material, the hard desk surface is cemented or otherwise adhered to the sub-cover. In contrast, the present invention has no sub-cover. The upper edges of its yielding bottom portion are either attached directly to the tray, or it has a detachable yielding bottom portion in the form of a self-contained sack with an upper surface that is directly attached to the bottom tray surface. In addition, while the Jennings invention comprises dry, flowable material, it is important for the present invention to be filled with inert, non-toxic, non-allergenic, and lightweight soft fill material that is either granular or filamentous, or a combination thereof, to include but not be limited to polystyrene beads, polyester, and fiberglass. The present invention must also have sturdy handles for confident transport of food and tableware, something not contemplated by the Jennings invention. Further, the present invention has a removable high-friction mat, capable of being rolled up into a compact cylindrical storage configuration, and the upper tray surface must be smooth for non-slip engagement with the high-friction mat. Also, although not critical, it is contemplated for the perimeter rim of the present invention to have a minimum height dimension of approximately one inch, as well as one or more optional recesses in the upper tray surface for enhanced retention and upright positioning of food containers that are either very full or have easily spilled contents. No perimeter rim of an inch or more, sturdy handle, or recess for a glass/mug/bottle/cup/can, is taught by the Jennings invention. Further, the present invention is also different from the Saxton invention, which is a take-apart pouch tray having a limp open-top pouch in detachable sealed relation with a peripheral depending sidewall. The Saxton invention further has a rigid planar top tray, and a replaceable limp closed bag in the pouch that is partially filled with lightweight flowable granules, with all components being washable. Different limp closed bags having distinguishable volumes of granules can be exchanged one for the other to vary pouch height. In contrast, the present invention has sturdy handle means, a removable high-friction mat that can have thermal properties, a smooth upper tray surface for non-slip engagement with the high-friction mat, and inert, non-toxic, non-allergenic, and lightweight soft fill material that can include filamentous and/or granular types of material. Since the yielding bottom portion of the present invention must conform to the lap or surface upon which it is placed, and provide cushioning to protect a user&#39;s lap from the weight of the tray, food, and tableware, it is contemplated for a substantial amount of fill material to be used within the yielding bottom portion of the present invention, and it would not be limp. Preferably, although not limited thereto, the height ratio of yielding bottom portion to tray is approximately 2:1, with a perimeter rim that typically has a minimum height dimension of approximately one inch. Illustrations of the Saxton invention show its limp closed bag to sidewall height ratio typically being at least 3:1 or 4:1. Also, when the present invention tray member is removable from its yielding bottom portion, its yielding bottom portion is manufactured as a self-contained sack and attachment of the tray member to the yielding bottom portion is achieved through the bottom surface of the tray member, not its sidewalls. Thus, neither the Jennings invention nor the Saxton invention, alone or in combination., teaches the present invention, and no other invention is known that has all of the features and advantages provided by the present invention. 
   BRIEF SUMMARY OF THE INVENTION—OBJECTIVES AND ADVANTAGES 
   The primary objective of this invention is to provide a serving tray that is lightweight and easy to use for transporting food and tableware to a diner without spills, and one that is also comfortable to a diner when placed upon his or her lap with the upper tray surface in a substantially horizontally-extending or slightly tilted position. It is a further objective of this invention to provide a serving tray that during routine transport and use assists containers placed upon its upper surface to remain in upright and fixed positions until needed for use. A further objective of this invention is to provide a serving tray with an aesthetically pleasing configuration and surface decorations that enhance the dining experience of its user. It is also an objective of this invention to provide a serving tray that has sturdy handle means for controlled/confident transport. A further objective of this invention is to provide a serving tray with a surface that during use can be readily swept clean of crumbs and other small pieces of food created during the dining process. It is also an objective of this invention to provide a serving tray and yielding bottom portion that are easily cleaned and otherwise maintained between uses. 
   The present invention helps its user to transport food items with confidence and in a controlled manner to its destination, since it has sturdily constructed handles, a perimeter rim configured to limit the extent of tableware and other object travel across the upper tray surface when unanticipated events cause some movement to occur, and high-friction means configured to help maintain tableware and food containers in their initial upright and fixed positions on its upper tray surface during transport. It is contemplated for the perimeter rim to be sufficiently high to properly fulfill its retaining function, but not so high as to hinder dining use. Preferably, the perimeter rim has a minimum height dimension of approximately one-inch or two-and-one-half centimeters. Comfort of the person dining from the present invention tray is enhanced by its ability to be positioned at different heights relative to the user. Although the easiest option is for the present invention tray to be placed directly upon the lap of its user with its yielding bottom portion conforming to the configuration of the user&#39;s lap while allowing the upper tray surface to remain in a substantially horizontally-extending or slightly tilted position, in the alternative the yielding bottom portion of the present invention serving tray can be easily positioned upon a blanket, pillow, or other object that is supported comfortably upon the user&#39;s lap, whereby it conforms to the configuration of that object while maintaining the upper tray surface in the desired horizontally-extending or slightly tilted position and further raising the upper tray surface to a height that is better adapted to the user&#39;s convenience, comfort, and/or need. Use of its removable high-friction mat also helps the present invention prevent food containers from shifting position during transport, as well as during dining by those having weakened physical states and/or diminished eyesight. Further, maintenance is reduced and aided by its design, whereby its high-friction mat protects the tray&#39;s upper surface from spills, the high-friction mat material reduces spills during transport and eating, the removable nature of its high-friction mat improves the speed and ease of cleaning the mat and upper tray surface, the perimeter groove into which crumbs and other food debris can be swept aside during use consolidates debris for easier cleanup between uses, and in detachable embodiments the detachable self-contained yielding bottom portion makes for less awkward cleaning of the upper tray surface, as well as easy laundering and/or exchange of one yielding bottom portion for another. The dining experience is improved through use of the present invention serving tray. Its mat can optionally have thermal properties to assist in maintaining the optimum temperature of food until it is consumed, hot or cold. Further, the upper tray surface is smooth, and it also can have decorative markings and/or a perimeter or other configuration that enhances its aesthetic appeal. The perimeter rim, sturdy handles, removable high-friction mat, and/or yielding bottom portion can also have any combination of decorative markings, surface texture, perimeter configuration, arcuate or curvilinear structure, or other configuration that enhances its aesthetic appeal. In embodiments having a detachable yielding bottom portion, one self-contained bottom portion can be exchanged for another with a different type of material, decorative markings, texture, and/or configuration, providing visual stimulus for those who are bedridden and pleasant variation for others. Also, use of the perimeter groove allows the dining person to have control over the desired level of cleanliness and clutter visible on the upper tray surface, and it facilitates clean up after dining since dry food crumbs swept into the perimeter groove remain dry and are more readily discarded than those that are left on the upper tray surface and become soggy as a result of contact with spilled liquids and other food residue. 
   While the description herein provides preferred embodiments of the present invention, it should not be used to limit its scope. For example, variations of the present invention, while not shown and described herein, can also be considered within the scope of the present invention, such as variations in the length and width dimensions of its upper tray surface, the number of sides incorporated into the perimeter of its upper tray surface, the height dimension of its perimeter rim, the number of recesses used in its upper tray surface, the type of inert and non-toxic fill material used within its yielding bottom portion, the configuration of its handles, and the size, number, and type of two-part quick-release fasteners used in detachable embodiments. Thus, the scope of the present invention should be determined by the appended claims and their legal equivalents, rather than being limited to the examples given.

   DETAILED DESCRIPTION OF THE INVENTION 
     FIGS. 1 ,  2 , and  3  show a first and most preferred embodiment  2  of the comfortable serving tray of the present: invention, although the perimeter groove  16  and the beverage container recess  12  shown as a part thereof are optional features.  FIG. 1  shows first preferred embodiment  2  having a horizontally-extending high-friction mat  14  positioned directly upon and substantially covering a horizontally-extending smooth upper tray surface (similar to that shown in  FIGS. 4 and 5  by the number  22 ), opposing end panels  6  each having a sturdy handle  8  with a horizontally-extending elongated aperture  18  therethrough, a perimeter rim  4  extending between opposing end panels and contiguous therewith, a perimeter groove  16  adjacent to one perimeter rim  4  and at least one end panel  6 , a yielding bottom portion  10  downwardly extending below upper tray surface  22 , and a recess  12  for a container (not shown) configured to hold an easily spilled food or beverage, such as but not limited to a glass, bottle, mug, cup, or can. Although  FIG. 1  shows high-friction mat  14  to have a substantially rectangular configuration with end panels  6  being substantially planar, it is also considered to be within the scope of the present invention for end panels  6  to each have an angled and/or arcuate configuration as long as it provides a sturdy handle  8 , and for high-friction mat  14  and upper tray surface  22  to have other elongated configurations, such as but not limited to that of an oval, elongated pentagon, elongated hexagon, elongated octagon, and the like. Also, although not shown, high-friction mat  14  may have a surface texture or decorative design, a combination of colors, one or more logos, and/or alpha-numeric markings. In contrast however, it is contemplated for upper tray surface  22  to be smooth so that a high level of non-slip adhesion is possible between it and high-friction mat  14 . A high-friction mat  14  smaller than that illustrated in  FIG. 1  is also contemplated. High-friction mat  14  should be promptly removable from upper tray surface  22  for easy cleaning and when a person prefers to dine directly from upper tray surface  22 .  FIG. 1  shows high-friction mat  14  having a hole therethrough (although the hole has been given no numeric designation) through which recess  12  in upper tray surface  22  can be seen. In the alternative, as shown in  FIG. 6 , it is also contemplated for the portion of high-friction mat  14  over recess  12  to have a complementary receptacle  20  conforming to the configuration of recess  12  that provides additional assistance in maintaining the beverage or food container positioned within recess  12  in a substantially upright position, and may also provide a selected amount of thermal insulation. The diameter and depth dimensions of recess  12  are not critical, although it is preferred for recess  12  to have a circular configuration suitable for containing the bottommost portion of the type of glass, bottle, or can commonly used to contain cold beverages, or the type of mug or cup used to contain a hot beverage, food, or soup (not shown). Should first preferred embodiment  2  be made with recess  12  having a diameter dimension sufficiently large to accommodate the largest cup, bottle, can, glass, or mug contemplated for routine use therewith and high-friction mat  14  with its receptacle  20  is not used, in the alternative although not shown, one or more removable inserts could be used as needed in recess  12  to stabilize smaller diameter cups, bottles, cans, glasses, and mugs during transport.  FIG. 1  also shows perimeter groove  16  adjacent to one perimeter rim  4  and one end panel  6 . Although perimeter groove  16  may extend around the entire perimeter edge of upper tray surface  22 , as shown in  FIG. 4 , it is also contemplated for perimeter groove  16  to extend along only one perimeter rim  4  or one end panel  6 , both perimeter rims  4 , both end panels  6 , or in the alternative to not be present at all, as shown in  FIG. 5 . The width dimension of perimeter groove  16  is not critical, but at a minimum should be sufficiently large to contain the crumbs of several very flaky or crumbly pieces of bread or pastries, such as a croissant. However, in most applications perimeter groove  16  does not have to be very wide or deep to perform its crumb-holding function. Another function contemplated for perimeter groove  16 , although not shown, which might dictate a slightly larger width and/or depth dimension for perimeter groove  16 , is to provide a place to temporarily store high-friction mat  14  when it is removed from upper tray surface  22  and set aside in a rolled/cylindrical storage configuration.  FIG. 1  shows perimeter rim  4  having a small height dimension that would not interfere with the access of a person reaching for food or tableware (not shown) positioned on high-friction mat  14  or in recess  12 .. Yet perimeter rim  4  needs to have a minimum height dimension of approximately one-inch or two-and-one-half centimeters, to be sufficiently tall to prevent food or tableware from traveling beyond perimeter groove  16  during routine transport. Further, although  FIG. 1  shows yielding bottom portion  10  having a thickness dimension that is approximately twice the height of perimeter rim  4 , and such proportion is preferred, the  2 : 1  height ratio of yielding bottom portion  10  to perimeter rim  4  is not critical. Instead, it is critical for yielding bottom portion  10  to have sufficient fill material and a sufficiently thick height dimension for comfortable support of the weight of upper tray surface  22  and tableware (not shown), as well as food items supported thereon (not shown) upon the lap of a diner. Thus, as shown in  FIG. 2  and to provide the necessary level of comfort, it is contemplated for yielding bottom portion  10  in first preferred embodiment  2  to be substantially filled with granular material  24  so that it can conform to the surface configuration of the lap or other surface upon which it is placed, and it would not be limp. Filamentous soft fill material, although not shown, to also be used within yielding bottom portion  10 , alone or in combination with granular material  24 . Therefore, it is considered to be within the scope of the present invention for soft fill material can be any filamentous or other material that provides support for perimeter rim  4 , end panels  6 , and upper tray surface  22  while at the same time being comfortable to the user (not shown) when placed directly on his or her lap. Yielding bottom portion  10  should provide a substantially horizontally-extending orientation for high-friction mat  14  and upper tray surface  22  for dining use, however, since some tilting of upper tray surface  22  toward a user may provide an advantage in selected applications, a slightly tilted orientation of upper tray surface  22  is also considered to be within the scope of the present invention. Although not critical, it is also contemplated for the fabric or other material used in the most preferred embodiment of the present invention for the creation of yielding bottom portion  10  to be washable, flexible, and soft. Loosely woven fabrics and those having a rough surface texture would typically be avoided. In addition, the material used for yielding bottom portion  10  can be devoid of surface decoration, as shown in  FIG. 1 , or alternatively, although not shown, have any surface texture or decorative design, one or more logos, any color or color combination, and/or one or more alpha numeric markings. The means of attaching yielding bottom portion  10  beneath upper tray surface  22  is not critical, and can be accomplished by any means providing a secure connection therebetween, such as but not limited to adhesive means, bonding agent, decorative tacks, or a combination thereof or other attachment means. Further, the configuration and size of handles  8  and elongated aperture  18  shown in  FIG. 1  are not critical, and handles  8  or apertures  18  may be of any perimeter configuration, angular or arcuate or combination, that provides a sturdy grip for the hands of its user. Handles  8  may also have a greater height dimension than is shown in  FIG. 1 , but should not be so large as to provide additional weight to first preferred embodiment  2  without affording significant structural or aesthetic benefit. 
     FIGS. 2 and 3  also show first embodiment  2  having a yielding bottom portion  10  with a height dimension that is approximately twice that of end panel  6 . Although  FIG. 2  shows yielding bottom portion  10  being somewhat loosely filled with granular material  24 , it is not meant to be limp, but to be substantially filled with soft fill material to provide comfortable support of upper tray surface  22 , perimeter rims  4 , end panels,  6 , and tableware thereon when yielding bottom portion  10  is placed upon the lap of its user. In the alternative, although not shown, it is also contemplated for the yielding bottom portion  10  of first preferred embodiment  2  to contain soft filamentous fill material, alone or in combination with granular material  24 . In addition,  FIG. 2  shows high-friction mat  14  positioned upon upper tray surface  22 , a perimeter groove  16  adjacent to end panel  6 , and a sturdy handle  8  rising above end panel  6 .  FIG. 3  shows end panel  6  having; sturdy handle  8  upwardly depending therefrom and centered thereabove, with one elongated and horizontally-extending aperture  18  through sturdy handle  8 .  FIG. 3  further shows aperture  18  being centered both horizontally and vertically through sturdy handle  8 . While not critical, approximate centering of aperture  18  within sturdy handle  8 , as well as centering of sturdy handle  8  within end panel  6 , facilitates comfortable and balanced transport of first preferred embodiment  2  and is preferred. It is contemplated that aperture  18  could be smaller or larger than what is shown in  FIG. 3 , and although not shown and not preferred, it is considered to be within the scope of the present invention for sturdy handles  8  to each have a sequence of two or more smaller apertures  18  that are each configured and/or positioned in sequence for comfortable insertion of one or more the fingers of a person needing to transport it. As can be seen from the combination of  FIGS. 1 ,  2 , and  3 , end panels  6  and perimeter rim  4  are vertically extending, however, neither has to be in exact vertical orientation. In fact the slightly outward non-vertical orientation shown in  FIGS. 1–3  is preferred as it provides a user with a little more room for lateral and forward movement in reaching food and tableware items positioned on high-friction mat  14 . 
     FIGS. 4 and 5  respectively show a second preferred embodiment  30  and a third preferred embodiment  32  of the present invention comfort serving tray.  FIG. 5  shows second preferred embodiment  30  having a smooth and substantially horizontally-extending upper tray surface  22 , opposing end panels  6  each having a sturdy handle  8 , a perimeter rim  4  extending between opposing end panels  6 , an elongated aperture  18  centered through each sturdy handle  8 , and a perimeter groove  16  on all four sides of upper tray surface  22 . In contrast,  FIG. 5  shows third preferred embodiment  32  having a smooth and substantially horizontally-extending upper tray surface  22 , opposing end panels  6  each having a sturdy handle  8 , a perimeter rim  4  extending between opposing end panels  6 , and an elongated aperture  18  centered through each sturdy handle  8 . Although a high-friction mat  14  is not shown in  FIGS. 4 and 5  upon upper tray surface  22 , it is contemplated that a high-friction mat  14  could be used with second preferred embodiment  30 , as well as third preferred embodiment  32 . For effective use of high-friction mat  14 , it is contemplated for upper tray surface  22  to be smooth, and perhaps also shiny, to provide the necessary amount of adhesion between it and high-friction mat  14  to maintain tableware and food in substantially fixed positions thereon during transport.  FIGS. 4 and 5  further show perimeter rim  4  and end panels  6  vertically extending, however, not in exact vertical orientation, whereby each angles outwardly away from its opponent. While such an outwardly angled configuration is preferred, it is not critical. 
     FIG. 6  shows the high-friction mat  14  of  FIG. 1  having a substantially planar non-woven configuration and a receptacle  20  into which the bottommost portion of a container of liquids or easily spilled food can be positioned. When receptacle  20  is used, it assists in the secure positioning of a bottle, can, glass, cup, or mug within recess  12  during present invention transport. In the alternative, although not shown, in place of receptacle  20  it is contemplated for high-friction mat  14  to have a hole therethrough configured for insertion of a bottle, glass, cup, can, mug, or other container intended for direct placement into a correspondingly positioned recess  12  within upper tray surface  22 .  FIG. 7  shows an alternative mat structure  42  with a center woven portion  26  and a distinguishable perimeter portion  28 . The woven/mesh configuration of center woven portion  26  can provide a heat protecting function for upper tray surface  22 . Although not limited thereto, center woven portion  26  could have more pronounced thermal characteristics as compared to distinguishable perimeter portion  28 , and distinguishable perimeter portion  28  could have enhanced non-slip gripping capability relative to center woven portion  26 . Although not shown, it is also contemplated for the scope of the present invention to include other mat configurations with differing combinations of woven and non-woven materials, for aesthetic as well as functional purposes, to include but not be limited to distinguishable perimeter portions  28  having width dimensions different from that shown in  FIG. 7 , such as a non-woven mat with a distinctive perimeter portion  28  or an alternative mat structure  42  only with center woven portion  26 , a mat with a left (or right) half that is woven and the other half being non-woven, and a woven mat with no distinctive perimeter portion  28 . The critical element of mat configuration is its high-friction composition, surface texture, or combination thereof, which prevents items placed thereon from slipping or sliding across its exposed surface, and not its size, surface decoration, thickness dimension, color, perimeter configuration (which does not have to be limited to the rectangular configuration shown in  FIGS. 6 and 7 ), or flexibility although high-friction mat  14  and alternative mat structure  42  should be able to be rolled up into a cylindrical configuration for compact storage when its use is not needed or desired. 
     FIGS. 8 and 9  illustrate a fourth preferred embodiment of the present invention  34  having a self-contained yielding bottom portion  10  detachably connected via multiple two-part quick-release fasteners  38   a  and  38   b  to bottom tray surface  36 .  FIG. 9  shows fourth preferred embodiment  34  having a detachable yielding bottom portion  10  with a self-contained and sealed configuration, while  FIG. 8  shows the corresponding bottom tray surface  36  to which the top surface  40  of self-contained yielding bottom portion  10  would be securely attached with quick-release fasteners  38   a  and  38   b . It is intended for the upper tray surface  22  in fourth preferred embodiment  34  to be smooth, and perhaps shiny, for good adhesion of high-friction mat  14  thereto. Although it is preferred for soft filamentous fill material (not shown), granular material  24 , and/or a combination thereof to substantially fill yielding bottom portion  10 , yielding bottom portion  10  must not be too firm so that it will be able to conform to the lap of a user or other surface upon which it is placed. The number and size of quick-release fasteners  38   a  and  38   b  used are not critical, as long as they provide secure attachment between the bottom tray surface  36  and the top surface  40  of yielding bottom portion  10 . Ease of connection and release, as well as cost benefit, are also considerations used in selecting the type of fasteners used for  38   a  and  38   b . Thus, a number of fasteners  38   a  and  38   b  larger than that shown in  FIGS. 8 and 9  could be used in fourth preferred embodiment  34 , as well as fasteners  38   a  and  38   b  that are smaller that those shown in  FIGS. 8 and 9 . It is even considered within the scope of the present invention, although not necessarily preferred when cost is a factor, for one elongated fastener  38   a  and one elongated fastener  38   b  to be used where appropriate for the intended application, with fasteners  38   a  and  38   b  each extending the full perimeter of top surface  40  and bottom tray surface  36 . Also, although the fasteners  38   a  and  38   b  used in  FIGS. 8 and 9  appear as hook-and-pile fasteners, and hook-and-pile fasteners are preferred, the use of other types of quick-release fasteners for  38   a  and  38   b  is also contemplated. Further, when hook-and-pile fasteners  38   a  and  38   b  are used, it is preferred for the pile portion to be attached to bottom tray surface  36  and the corresponding hook portion attached to yielding bottom portion  10  for enhanced user comfort should bottom tray surface  36  ever be used apart from yielding bottom portion  10  for any purpose.  FIG. 9  further shows a recess  12  in upper tray surface  22 , a perimeter groove  16 , a sturdy handle  8  on each end panel  6 , a perimeter rim extending between end panels  6 , an elongated aperture  18  through each sturdy handle  8 , and an arrow pointing to bottom tray surface  36 , while  FIG. 8  shows recess  12  extending beyond bottom surface  36 , a sturdy handle  8  on each end panel  6 , perimeter rim  4  extending between end panels  6 , and an elongated aperture  18  through each sturdy handle  8 . In contrast, although not shown, aperture  18  could have a configuration different from that shown in  FIGS. 8 and 9 , such as but not limited to a more rounded or angular configuration. Further, although not shown and where appropriate to the application, for ease of laundering the self-contained yielding bottom portion  10  shown in  FIG. 9 , a substantially hidden zipper or two-part quick-release fastener such as  38   a  and  38   b , or a sealable slit or overlapping configuration within top surface  40 , could be used that would allow intact filamentous soft fill material within yielding bottom portion  10  to be readily removed as a unit and then subsequently replaced when laundering is complete. However, for simple spot cleaning of small sections of yielding bottom portion  10 , removal of the soft fill material therein is not contemplated. Upper tray surface  22  can be devoid of surface markings, as shown in  FIG. 9 , or be decorated with surface pictures or other designs (not shown). Upper tray surface  22  is preferably made from wood or plastic materials, although not limited thereto. The most important considerations for the material used for upper tray surface  22  are its weight, as the present invention should he sufficiently lightweight for confident and controlled transport by a user, and the ability of the material to form a smooth, and perhaps also shiny, upper tray surface  22  for secure adhesion thereto of high-friction mat  14  or alternative mat structure  42 . High-friction mat  14  and alternative mat structure  42  can be made from any rubberized or plastic material having high-friction characteristics, or in the alternative its non-slip character can be largely attributable to its surface texture and/or design, or both. Since they are to be used with food, it is important that high-friction mat  14  and alternative mat structure  42 , as well as all other materials used for the present invention, to be non-toxic and readily washable. In addition, the materials used for high-friction mat  14  and alternative mat structure  42  can have thermal characteristics that protect upper tray surface:  22  from damage what high temperature food containers are repeated placed thereon. Also, the thermal characteristics of high-friction mat  14  and alternative mat structure  42  can assist in maintaining elevated and reduced temperatures in served food during transport to provide more appetite-stimulating consumption for the person intending to cat it. Further, the fabrics used for yielding bottom portion  10  can vary in quality and design, but it is preferred that they not be too loosely woven for inadvertent loss of soft fill material, or abrasive to the touch. Although not limited thereto, the soft fill material used within yielding bottom portion  10  can be made from fiberglass or polyester, or inert or other non-allergenic material, and granular fill material  24  can include polystyrene beads exclusively, or in part.
