Mattress comprising a plurality of tubular foam springs in one or more side-to-side channels

Abstract

A mattress comprising a first layer comprising at least one channel extending laterally from a first side of the layer to an opposite side of the layer, and a plurality of tubular foam springs disposed in each channel. A mattress assembly comprising the mattress and a mattress foundation.

What is claimed is: 
     
         1 . A mattress, comprising:
 a first layer comprising at least one channel extending laterally from a first side of the layer to an opposite side of the layer; and   a plurality of tubular foam springs disposed in each channel.   
     
     
         2 . The mattress of  claim 1 , further comprising:
 a comfort layer disposed above the first layer.   
     
     
         3 . The mattress of  claim 1 , wherein the comfort layer comprises a foam. 
     
     
         4 . The mattress of  claim 2 , wherein the foam is a viscoelastic foam. 
     
     
         5 . The mattress of  claim 1 , wherein the first layer comprises a non-viscoelastic foam. 
     
     
         6 . The mattress of  claim 1 , wherein the first layer comprises at least:
 a first zone having one or more channels at a first channel density, and a first density of tubular foam springs in each channel; and   a second zone having one or more channels at a second channel density, and a second density of tubular foam springs in each channel;   wherein the first channel density differs from the second channel density; the first density of tubular foam springs differs from the second density of tubular foam springs; or both.   
     
     
         7 . A mattress assembly, comprising:
 a mattress, comprising:
 a first layer comprising at least one channel extending laterally from a first side of the layer to an opposite side of the layer; and 
 a plurality of tubular foam springs disposed in each channel; and 
   a mattress foundation disposed under the mattress.   
     
     
         8 . The mattress assembly of  claim 7 , wherein the mattress further comprises a comfort layer disposed above the first layer. 
     
     
         9 . The mattress assembly of  claim 7 , wherein the first layer comprises a non-viscoelastic foam. 
     
     
         10 . The mattress assembly of  claim 7 , wherein the first layer comprises at least:
 a first zone having one or more channels at a first channel density, and a first density of tubular foam springs in each channel; and   a second zone having one or more channels at a second channel density, and a second density of tubular foam springs in each channel;   wherein the first channel density differs from the second channel density; the first density of tubular foam springs differs from the second density of tubular foam springs; or both.   
     
     
         11 . A mattress, comprising:
 a first layer comprising at least one channel extending laterally from a first side of the layer to an opposite side of the layer;   a plurality of tubular foam springs disposed in each channel; and   a viscoelastic foam layer disposed directly above the first layer.   
     
     
         12 . The mattress of  claim 11 , wherein the first layer comprises a non-viscoelastic foam. 
     
     
         13 . The mattress of  claim 11 , wherein the first layer comprises at least:
 a first zone having one or more channels at a first channel density, and a first density of tubular foam springs in each channel; and   a second zone having one or more channels at a second channel density, and a second density of tubular foam springs in each channel;   wherein either the first channel density differs from the second channel density, the first density of tubular foam springs differs from the second density of tubular foam springs, or both.
