Heat-dissipating bedding product

Abstract

The present invention relates to bedding product having heat-dissipation and support properties provided by structural protrusions on the surface of the bedding product. The bedding product may comprise a first layer of foam, that includes a base support having an upper surface and a lower surface and a plurality of open and closed protrusions located on the upper surface of the base support. Each open protrusion comprises a cavity formed therein, wherein the cavity has a depth of at least 0.5 inch

What is claimed is: 
     
         1 . A bedding product comprising a first layer of foam, wherein the first layer comprises:
 a base support having an upper surface and a lower surface;   a plurality of open protrusions positioned on the upper surface of the base support, each open protrusion comprising a cavity formed therein, wherein the cavity has a depth of at least 0.5 inch; and   a plurality of closed protrusions positioned on the upper surface of the base support.   
     
     
         2 . The bedding product of  claim 1 , wherein the cavity of the open protrusion has a depth of at least 1 inch. 
     
     
         3 . The bedding product of  claim 1 , wherein the open and closed protrusions are arranged in a pattern along the upper surface of the base support. 
     
     
         4 . The bedding product of  claim 1 , wherein:
 the open protrusions are arranged in one or more heat-sink groupings;   the closed protrusions are arranged in one or more support groupings, and   the heat-sink groupings and the support groupings are arranged in an alternating pattern.   
     
     
         5 . The bedding product of  claim 4 , wherein at least one of the heat-sink grouping comprises five or more open protrusions, and at least one of the support grouping comprises five or more closed protrusions. 
     
     
         6 . The bedding product of  claim 4 , wherein at least one of the support groupings forms a support zone positioned to correspond to a predetermined portion of a user's body and to provide resistance that promotes at least one effect on the user's body selected from blood circulation, recovery, and facilitation of slow wave sleep. 
     
     
         7 . The bedding product of  claim 1 , wherein the first layer defines an uppermost foam layer of the bedding product. 
     
     
         8 . The bedding product of  claim 1 , wherein the bedding product comprises a plurality of layers and the first layer is the uppermost support layer. 
     
     
         9 . The bedding product of  claim 1 , wherein top surfaces of the open and closed protrusions define an uppermost foam surface of the bedding product. 
     
     
         10 . The bedding product of  claim 1 , wherein at least one closed protrusion has a continuous top surface. 
     
     
         11 . The bedding product of  claim 1 , wherein at least one closed protrusion is solid. 
     
     
         12 . The bedding product of  claim 1 , wherein a top surface of at least one closed protrusion is outwardly rounded. 
     
     
         13 . The bedding product of  claim 1 , further comprising a second layer directly attached to the lower surface of the base support. 
     
     
         14 . The bedding product of  claim 13 , wherein the second layer is the same as the first layer. 
     
     
         15 . The bedding product of  claim 1 , wherein the base support has a thickness of about 0.25 inches to about 3 inches. 
     
     
         16 . The bedding product of  claim 1 , wherein the bedding product is a mattress. 
     
     
         17 . The bedding product of  claim 1 , wherein the bedding product is a mattress topper. 
     
     
         18 . The bedding product of  claim 1 , wherein the bedding product provides greater heat-dissipation than a bedding product comprising a base support without protrusions. 
     
     
         19 . The bedding product of  claim 1 , wherein the bedding product provides greater air flow than a bedding product comprising a base support without protrusions.
