Contiguous mattress system for adjustable base foundation

Abstract

A mattress and mattress system for an adjustable base foundation configured to accommodate two mattresses in a side-by-side relationship and independently articulate each of the two mattresses. The mattress generally includes an edge zone about a perimeter of a selected one of the lateral sides, and a comfort zone. The edge zone can have a greater firmness level than the comfort zone. The mattress system includes two mattresses in a side-by-side relationship, wherein each mattress includes the edge zone about the perimeter of a selected one of the lateral sides, and a comfort zone. The mattresses are arranged on the adjustable base foundation such that the exterior facing lateral sides of each mattress are defined by the edge zone. The comfort zone includes the interior facing lateral sides.

What is claimed is: 
     
         1 . A mattress comprising:
 a head end;   a foot end;   a first lateral side extending from the head end to the foot end;   a second lateral side extending from the head end to the foot end;   a comfort zone having a first firmness level, wherein the comfort zone defines a primary sleeping surface for the mattress; and   an edge zone having a second firmness level that is different than the first firmness level of the comfort zone, wherein the edge zone defines a perimeter of a selected one of the lateral sides.   
     
     
         2 . The mattress of  claim 1 , further comprising a retention system extending from a bottom surface thereof configured to fixedly attach the mattress to an underlying base foundation. 
     
     
         3 . The mattress of  claim 1 , wherein the underlying base foundation is an adjustable base foundation with one or more articulable sections. 
     
     
         4 . The mattress of  claim 1 , wherein the second firmness level of the edge zone is greater than the first firmness level of the comfort zone. 
     
     
         5 . The mattress of  claim 1 , wherein the first firmness level of the comfort zone is about 20 to about 35 pounds-force and the second first firmness level of the edge zone is about 45 to about 90 pounds-force. 
     
     
         6 . The mattress of  claim 1 , wherein the edge zone has a width from about 2 inches to about 10 inches. 
     
     
         7 . The mattress of  claim 1 , wherein the edge zone defines a perimeter of only a selected one of the lateral sides, a head end, and a foot end. 
     
     
         8 . The mattress of  claim 1 , wherein the edge zone defines a perimeter of only a selected one of the lateral sides, and a selected one of a head end and a foot end. 
     
     
         9 . The mattress of  claim 1 , wherein the comfort zone comprises foam, coil springs, or a combination thereof. 
     
     
         10 . The mattress of  claim 1 , wherein the edge zone comprises a fill material comprising foam, coil springs or a combination thereof. 
     
     
         11 . The mattress of  claim 2 , wherein the retention system is configured to couple the mattress to a non-articulable section of a base foundation. 
     
     
         12 . A mattress system for an adjustable base foundation configured to accommodate two mattresses in a side-by-side relationship and independently articulate each of the two mattresses, the mattress system comprising:
 an adjustable foundation dimensioned to accommodate two mattresses thereon and configured to independently adjust one or more articulable sections corresponding to each of the two mattresses; and   two mattresses disposed on the adjustable base foundation in a side-by-side relationship, wherein each of the two mattresses comprises a comfort zone having a first firmness and an edge zone at a perimeter thereof having a second firmness level that is different than the first firmness level of the comfort zone, wherein the edge zone defines the perimeter of only an exterior facing lateral side for each of the two mattresses in the side-by-side relationship.   
     
     
         13 . The mattress system of  claim 12 , wherein the edge zone further defines a perimeter of a head end and/or a foot end of each mattress in addition to the exterior facing lateral side. 
     
     
         14 . The mattress system of  claim 12 , wherein each of the two mattresses further comprises a retention system extending from a respective bottom surface thereof configured to fixedly attach each of the two mattresses to an underlying base foundation and prevent separation of the two mattresses during use thereof. 
     
     
         15 . The mattress system of  claim 12 , wherein the adjustable base foundation comprises two adjustable base foundations coupled to each together. 
     
     
         16 . The mattress system of  claim 12 , wherein the comfort zone has a first firmness level of about 20 to about 35 pounds-force and the edge zone has a second first firmness level of about 45 to about 90 pounds-force. 
     
     
         17 . The mattress system of  claim 12 , wherein the edge zone forms a continuous perimeter about the two mattresses when in the side-by-relationship.
