Adjustable mattress topper

Abstract

An adjustable body support system for accommodating the needed or desired support of multiple users. The system comprises an enclosure for housing a first support member and a second support member in respective first and second chambers. The first support member has a first foam layer secured to a second foam layer, wherein the first and second foam layers have different support characteristics. The second support member has a third foam layer secured to a fourth foam layer, wherein the third and fourth foam layers have different support characteristics. The first and second support members are removable from and securable in the first and second chambers, respectively.

1 . A body support system, comprising:
 an enclosure having a first chamber and a second chamber;   a first support member having a first foam layer secured to a second foam layer, wherein the first and second foam layers have different support characteristics; and   a second support member having a third foam layer secured to a fourth foam layer, wherein the third and fourth foam layers have different support characteristics, and wherein the first and second support members are removable from and securable in the first and second chambers, respectively.   
     
     
         2 . The system of  claim 1 , wherein the support characteristics include at least one of density, indention load deflection, thermal conductivity, firmness, softness, and material type. 
     
     
         3 . The system of  claim 1 , wherein the first foam layer includes an indention load deflection rating that is about 2-3 lbs greater than an indention load deflection rating of the second foam layer. 
     
     
         4 . The system of  claim 1 , wherein the third foam layer includes an indention load deflection rating that is about 2-3 lbs greater than an indention load deflection rating of the fourth foam layer. 
     
     
         5 . The system of  claim 1 , wherein one of the foam layers of the first and second support members includes a gel-infused foam layer, and wherein the other one of the foam layers of the first and second support members includes a non-gel-infused foam layer. 
     
     
         6 . The system of  claim 1 , wherein one of the foam layers of the first and second support members is softer than the other one of the foam layers of the first and second support members. 
     
     
         7 . The system of  claim 1 , wherein one of the foam layers of the first and second support members is firmer than the other one of the foam layers of the first and second support members. 
     
     
         8 . The system of  claim 1 , wherein the first and second support members are disposed in the enclosure such that the first foam layer and the third foam layer jointly form a substantially continuous upper support surface, and wherein the first foam layer has different support characteristics than the third foam layer. 
     
     
         9 . The system of  claim 1 , wherein one of the foam layers includes a gel disposed on a top surface. 
     
     
         10 . The system of  claim 9 , wherein the gel is applied on the top surface in liquid form. 
     
     
         11 . The system of  claim 10 , wherein the gel is applied using a brush or a spray device. 
     
     
         12 . A body support system comprising:
 a foam layer; and   a gel layer disposed on the foam layer, wherein the gel layer is applied in liquid form and allowed to cure on the foam layer.   
     
     
         13 . The system of  claim 12 , wherein the foam layer comprises a polyurethane foam having viscoelastic properties. 
     
     
         14 . The system of  claim 12 , wherein the gel layer comprises a polyurethane gel. 
     
     
         15 . The system of  claim 12 , wherein the gel layer has a height of about 0.004 inches to about 0.5 inches. 
     
     
         16 . A method for forming a foam apparatus, comprising:
 forming a plurality of holes in a foam layer;   depositing a layer of liquid gel on a surface of the foam layer; and   curing the layer of liquid gel to form a layer of solid gel.   
     
     
         17 . The method of  claim 16 , further comprising repeating the depositing step and the curing step until a total height of the layer of solid gel reaches a predetermined height. 
     
     
         18 . The method of  claim 16 , further comprising applying a powder on a top surface of the layer of solid gel. 
     
     
         19 . The method of  claim 16 , wherein the plurality of holes are through holes. 
     
     
         20 . The method of  claim 16 , wherein the layer of liquid gel is cured at room temperature.
