Mattresses with heat dissipation

Abstract

In one embodiment, a mattress comprises a core and a cushion layer positioned above the core. A fibrous air spacer layer is positioned above the cushion layer, and a layer of visco-elastic foam is positioned above the fibrous layer. This permits the fibrous layer to be sandwiched between the cushion layer and the layer of visco-elastic material.

What is claimed is: 
     
         1 . A mattress, comprising:
 a core;   a cushion layer positioned above the core;   a fibrous air spacer layer positioned above the cushion layer; and   a layer of visco elastic foam position above the fibrous layer such that the fibrous layer is sandwiched between the cushion layer and the layer of visco elastic material.   
     
     
         2 . A mattress as in  claim 1 , wherein the cushion layer comprises polyurethane. 
     
     
         3 . A mattress as in  claim 1 , wherein the fibrous air spacer layer comprises multiple strands of fibers positioned between a honey comb layer. 
     
     
         4 . A mattress as in  claim 1 , wherein the fibrous air spacer layer comprises a two warp-knitted layers which are connected by pile mono filaments in single knitting process. 
     
     
         5 . A mattress as in  claim 1 , wherein the fibrous air spacer layer has a thickness that is in the range from about 1/16 inch to about 2 inches. 
     
     
         6 . A mattress as in  claim 1 , wherein the at least one of the cushion layer and the layer of visco elastic foam has a surface that has been modified to be non-planar. 
     
     
         7 . A mattress as in  claim 1 , wherein the core comprises at least one of a spring coil, a pocket spring, an air bladder, and latex. 
     
     
         8 . A mattress as in  claim 1 , wherein the layer of visco elastic foam has a thickness that is in the range from about 0.5 inch to about 3 inches, and wherein the cushion layer has a thickness in the range from about 1 inch to about 12 inches. 
     
     
         9 . A mattress, comprising:
 a core;   at least one cushion layer positioned above the core; and   a fibrous air spacer layer positioned between the cushion layer and the core.   
     
     
         10 . A mattress as in  claim 9 , wherein the cushion layer comprises a layer of visco elastic foam positioned, with the fibrous layer being sandwiched between the cushion layer and the core. 
     
     
         11 . A mattress as in  claim 9 , wherein the cushion layer comprises a first cushion layer, and further comprising a second cushion layer, and wherein the fibrous air spacer layer is positioned between the first cushion layer and the second cushion layer. 
     
     
         12 . A mattress as in  claim 11 , wherein the first and second cushion layers are constructed of a material selected from a group consisting of viscoelastic foam, polyurethane foam, latex, air and a gel. 
     
     
         13 . A mattress as in  claim 9 , wherein the fibrous air spacer layer comprises multiple strands of fibers positioned between a honey comb layer. 
     
     
         14 . A mattress as in  claim 9 , wherein the fibrous air spacer layer comprises a two warp-knitted layers which are connected by pile mono filaments in single knitting process. 
     
     
         15 . A mattress as in  claim 9 , wherein the fibrous air spacer layer has a thickness that is in the range from about 1/16 inch to about 2 inches. 
     
     
         16 . A mattress as in  claim 9 , wherein the at least one of the cushion layer has a surface that has been modified to be non-planar. 
     
     
         17 . A mattress as in  claim 9 , wherein the core comprises at least one of a spring coil, a pocket spring, an air bladder, and latex.
