Mattresses including a zoned cushioning layer and related methods

Abstract

Mattress assemblies are disclosed herein. The mattress assemblies can include a multilayered construction having a base layer, a coil layer, and a zoned cushioning layer. The zoned cushioning layer can include two or more cushioning members made of an elastomeric cushioning material. The cushioning members can be disposed in a hip region, a shoulder region, and/or a leg region of the mattress assembly. One or more support and/or comfort layers can also be included.

1 . A mattress assembly, comprising:
 a base layer;   a coil layer; and   a zoned cushioning layer, wherein the zoned cushioning layer comprises at least two cushioning members spaced apart along a longitudinal length of the zoned cushioning layer, each of the cushioning members extending laterally across the zoned cushioning layer.   
     
     
         2 . The mattress assembly of  claim 1 , wherein the base layer comprises a polyurethane foam or a latex foam. 
     
     
         3 . The mattress assembly of  claim 1 , wherein the coil layer comprises a plurality of encased metal coils. 
     
     
         4 . The mattress assembly of  claim 1 , wherein the zoned cushioning layer comprises three cushioning members spaced apart along the longitudinal length of the zoned cushioning layer. 
     
     
         5 . The mattress assembly of  claim 1 , wherein each of the cushioning members comprises an elastomeric cushioning material. 
     
     
         6 . The mattress assembly of  claim 5 , wherein the elastomeric cushioning material comprises a styrene-based copolymer. 
     
     
         7 . The mattress assembly of  claim 1 , wherein each cushioning member comprises a plurality of buckling walls that define hollow columns. 
     
     
         8 . The mattress assembly of  claim 1 , further comprising a support layer disposed between the coil layer and the zoned cushioning layer. 
     
     
         9 . The mattress assembly of  claim 1 , further comprising a comfort layer disposed above the zoned cushioning layer, the comfort layer comprising a memory material. 
     
     
         10 . The mattress assembly of  claim 9 , further comprising a support layer disposed between the zoned cushioning layer and the comfort layer. 
     
     
         11 . A mattress assembly, comprising:
 a base layer;   a coil layer; and   a zoned cushioning layer, wherein the zoned cushioning layer comprises at least three cushioning members spaced apart along a longitudinal length of the zoned cushioning layer, each of the cushioning members extending laterally across the zoned cushioning layer;   wherein a first cushioning member is disposed in a hip region, a second cushioning member is disposed in a shoulder region, and a third cushioning member is disposed in a leg region; and   wherein each cushioning member comprises an elastomeric material that comprises a plurality of buckling walls that define hollow columns.   
     
     
         12 . The mattress assembly of  claim 11 , wherein the base layer comprises a polyurethane foam or a latex foam. 
     
     
         13 . The mattress assembly of  claim 11 , wherein the coil layer comprises a plurality of encased metal coils. 
     
     
         14 . The mattress assembly of  claim 11 , wherein the elastomeric cushioning material comprises a styrene-based copolymer. 
     
     
         15 . The mattress assembly of  claim 11 , further comprising a support layer disposed between the coil layer and the zoned cushioning layer. 
     
     
         16 . The mattress assembly of  claim 11 , further comprising a comfort layer disposed above the zoned cushioning layer, the comfort layer comprising a memory material. 
     
     
         17 . The mattress assembly of  claim 16 , further comprising a support layer disposed between the zoned cushioning layer and the comfort layer. 
     
     
         18 . A mattress assembly, comprising:
 a base layer;   a coil layer;   a first support layer;   a zoned cushioning layer, wherein the zoned cushioning layer comprises at least three cushioning members spaced apart along a longitudinal length of the zoned cushioning layer, each of the cushioning members extending laterally across the zoned cushioning layer, wherein a first cushioning member is disposed in a hip region, a second cushioning member is disposed in a shoulder region, and a third cushioning member is disposed in a leg region, and wherein each cushioning member comprises an elastomeric material that comprises a plurality of buckling walls that define hollow columns; and   a comfort layer.   
     
     
         19 . The mattress assembly of  claim 18 , wherein the comfort layer comprises a memory material. 
     
     
         20 . The mattress assembly of  claim 18 , wherein the elastomeric cushioning material comprises a styrene-based copolymer.
