Dual density systems and methods for bedding applications

Abstract

Embodiments include a dual density mattress including a base, the base having a first density, a plurality of cavities, where the plurality of cavities are defined by the base, a plurality of foam pillars, the foam pillars having a second density different from the first density, where the plurality of foam pillars are operably configured to be positioned within the plurality of cavities.

We claim: 
     
         1 . A dual density mattress comprising:
 (a) a base, the base having a first density;   (b) a plurality of cavities, wherein the plurality of cavities are defined by the base;   (c) a plurality of foam pillars, the plurality of foam pillars having a second density different from the first density, wherein the plurality of foam pillars are operably configured to be positioned within the plurality of cavities.   
     
     
         2 . The dual density mattress of  claim 1 , wherein the plurality of foam pillars are identical. 
     
     
         3 . The dual density mattress of  claim 1 , wherein the plurality of foam pillars are constructed from different materials. 
     
     
         4 . The dual density mattress of  claim 1 , wherein the base has a first section with a first set of properties and a second section with a second set of properties, wherein the first set of properties are different from the second set of properties. 
     
     
         5 . The dual density mattress of  claim 4 , wherein the first section includes foam pillars constructed from a first material and the second section includes foam pillars constructed from a second material, wherein the first material is different from the second material. 
     
     
         6 . The dual density mattress of  claim 4 , wherein the first section includes foam pillars having a first density and the second section includes foam pillars having a second density, wherein the first density is different from the second density. 
     
     
         7 . The dual density mattress of  claim 6 , wherein the first section and the second section include foam pillars constructed from the same type of material. 
     
     
         8 . The dual density mattress of  claim 1 , wherein the each of the plurality of cavities has a substantially cylindrical configuration. 
     
     
         9 . The dual density mattress of  claim 1 , wherein each of the plurality of foam pillars has a substantially cylindrical configuration. 
     
     
         10 . The dual density mattress of  claim 1 , wherein each of the plurality of foam pillars is rotatable within each of the plurality of cavities. 
     
     
         11 . The dual density mattress of  claim 1 , wherein a top of each of the plurality of foam pillars is planar with a top of an upper section of the base. 
     
     
         12 . The dual density mattress of  claim 1 , wherein the base has an upper section and a lower section.
