Tray support for a mattress

Abstract

A mattress core support system in the form of a padded tray with a rigid bottom surface. The tray is comprised of four foam sides, providing edge support for persons sitting on the edge of the mattress, and containing therein a mattress core. The system is compatible with (and sized for) all standard mattress cores, e.g., coil spring, foam, foam/coil composite, and all known sizes. The mattress avoids the need for flipping and the associated increased cost of a two-sided mattress by including as its bottom member a rigid platform.

1 . A mattress, comprising, 
 a substantially rigid base platform,    a perimeter sidewall joined to the base platform and defining an interior cavity,    an innercore disposed within the cavity, and    an upholstery layer disposed over a top surface of the innercore.    
   
   
       2 . A mattress according to  claim 1 , wherein the substantially rigid base platform comprises a layer of high density foam.  
   
   
       3 . A mattress according to  claim 1 , wherein the substantially rigid base platform comprises a plurality of layers of foam to provide composite high density layer.  
   
   
       4 . A mattress according to  claim 1 , wherein the substantially rigid base platform is sufficiently rigid to provide a support surface that may be seated on to a bed frame, for providing a bed.  
   
   
       5 . A mattress according to  claim 1 , wherein the substantially rigid base platform comprises a wood, cardboard, plastic or foam member selected to provide support to the innercore.  
   
   
       6 . A mattress according to  claim 1 , wherein the innercore comprises a plurality of spring coils.  
   
   
       7 . A mattress according to  claim 1 , wherein the innercore is selected from the group of open coil innercores, fabric encased spring coil innercores, and springs in foam innercore.  
   
   
       8 . A mattress according to  claim 1 , wherein the innercore comprises a block of resilient foam.  
   
   
       9 . A mattress according to  claim 1 , wherein the innercore comprises a layer of latex.  
   
   
       10 . A mattress according to  claim 1 , further comprising a layer of upholstery over disposed over the innercore and the perimeter wall.  
   
   
       11 . A mattress according to  claim 1 , further comprising a layer of plain sheeting disposed over an exterior face of the substantially rigid base platform to provide a non-upholstered non-sleeping surface.  
   
   
       12 . A mattress according to  claim 1 , wherein the perimeter sidewall comprises at least two rigid foam sidewalls.  
   
   
       13 . A mattress according to  claim 1 , wherein the perimeter sidewall comprises at least four rigid foam sidewalls.  
   
   
       14 . A mattress according to  claim 1 , wherein the perimeter sidewall is joined by an adhesive joint to the substantially rigid base platform.  
   
   
       15 . A mattress according to  claim 14 , wherein the adhesive joint includes glue, tape, adhesive patches.  
   
   
       16 . A mattress according to  claim 1 , wherein the perimeter sidewall is joined by a mechanical fastener to the rigid base platform.  
   
   
       17 . A mattress according to  claim 1 , further comprising a wire for securing the innercore against the substantially rigid base platform.  
   
   
       18 . A mattress according to  claim 1 , wherein a layer of upholstery is disposed over the innercore and attached to or adjacent the sidewall for securing the innercore within the cavity.  
   
   
       19 . A mattress according to  claim 1 , wherein the sidewall includes a joint for allowing the mattress to pivot between a reclined and an inclined position.  
   
   
       20 . A bed comprising 
 a mattress having    a substantially rigid base platform,    a perimeter sidewall joined to the base platform and defining an interior cavity, and    an innercore disposed within the cavity, and    a platform having a flat surface for receiving the mattress and raising the platform off the ground.
