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 trench extending laterally from a first side of the layer to an opposite side of the layer; a plurality of support members disposed in each trench; and a second layer disposed over at least the at least one trench. Another 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 support members disposed in each channel; and a second layer encompassing the first layer. A mattress assembly comprising one of the mattresses and a mattress foundation.

What is claimed is: 
     
         1 . A mattress, comprising:
 a first layer comprising at least one trench extending laterally from a first side of the layer to an opposite side of the layer;   a plurality of support members disposed in each trench; and   a second layer disposed over at least the at least one trench.   
     
     
         2 . The mattress of  claim 1 , wherein the second layer is disposed over substantially the entirety of the first layer. 
     
     
         3 . The mattress of  claim 1 , further comprising:
 a comfort layer disposed above the second layer.   
     
     
         4 . The mattress of  claim 1 , wherein the second layer comprises a foam. 
     
     
         5 . The mattress of  claim 4 , wherein the foam is a viscoelastic foam. 
     
     
         6 . The mattress of  claim 1 , wherein the first layer comprises a non-viscoelastic foam. 
     
     
         7 . The mattress of  claim 1 , wherein at least one support member is a tubular foam spring. 
     
     
         8 . The mattress of  claim 1 , wherein the first layer comprises at least:
 a first zone having one or more trenches at a first trench density, and a first density of support members in each trench; and   a second zone having one or more trenches at a second trench density, and a second density of support members in each trench;   wherein the first trench density differs from the second trench density, the first density of support members differs from the second density of support members, or both.   
     
     
         9 . 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 support members disposed in each channel; and   a second layer encompassing the first layer.   
     
     
         10 . The mattress of  claim 9 , further comprising:
 a comfort layer disposed above the second layer.   
     
     
         11 . The mattress of  claim 9 , wherein the second layer comprises a foam. 
     
     
         12 . The mattress of  claim 11 , wherein the foam is a viscoelastic foam. 
     
     
         13 . The mattress of  claim 9 , wherein the first layer comprises a non-viscoelastic foam. 
     
     
         14 . The mattress of  claim 9 , wherein at least one support member is a tubular foam spring. 
     
     
         15 . The mattress of  claim 9 , 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 support members in each channel; and   a second zone having one or more channels at a second channel density, and a second density of support members in each channel;   wherein the first channel density differs from the second channel density, the first density of support members differs from the second density of support members, or both.   
     
     
         16 . A mattress assembly, comprising:
 a mattress, comprising:
 a first layer comprising at least one trench extending laterally from a first side of the layer to an opposite side of the layer, at least one channel extending laterally from a first side of the layer to an opposite side of the layer, or both at least one trench and at least one channel; 
 a plurality of support members disposed in each trench or each channel; and 
 a second layer disposed over at least the at least one trench or encompassing the first layer if no trench is present in the first layer; and 
   a mattress foundation disposed under the mattress.   
     
     
         17 . The mattress assembly of  claim 16 , wherein the second layer is disposed over substantially the entirety of the first layer. 
     
     
         18 . The mattress assembly of  claim 16 , further comprising:
 a comfort layer disposed above the second layer.   
     
     
         19 . The mattress assembly of claim  201 , wherein the second layer comprises a viscoelastic foam. 
     
     
         20 . The mattress assembly of  claim 16 , wherein the first layer comprises at least:
 (A) a first zone having one or more trenches at a first trench density, and a first density of support members in each trench; and   a second zone having one or more trenches at a second trench density, and a second density of support members in each trench;   wherein the first trench density differs from the second trench density, the first density of support members differs from the second density of support members, or both;   (B) a first zone having one or more channels at a first channel density, and a first density of support members in each channel; and   a second zone having one or more channels at a second channel density, and a second density of support members in each channel;   wherein the first channel density differs from the second channel density, the first density of support members differs from the second density of support members, or both; or   (C) both (A) and (B).
