Support systems for a reclining or a sitting body

Abstract

A support system including a middle layer having two opposite convoluted sides positioned on the outer surface of the support system.

I claim: 
     
         1 . A mattress, comprising:
 a core comprising a first polyhedral foam layer and a second polyhedral foam layer, each of the first and second polyhedral foam layers comprising a first indentation load deflection, each of the first and second polyhedral foam layers further comprising a longitudinal planar first surface and a longitudinal convoluted second surface opposite and parallel to said first planar surface, said planar surface of said first polyhedral foam layer joined to said planar surface of said second polyhedral foam layer.   
     
     
         2 . The mattress of  claim 1  wherein the convoluted surface of the first and the second polyhedral foam layers of the core comprise a plurality of zones comprising peaks and valleys. 
     
     
         3 . The mattress of  claim 2  wherein the zones of peaks and valleys of the convoluted surface of the first polyhedral foam layer is identical to the peaks and valleys of the convoluted surface of the second polyhedral foam layer. 
     
     
         4 . The mattress of  claim 2  wherein the peaks and the valleys of the first polyhedral foam layer and the second polyhedral foam layer are positioned on opposite sides of the core. 
     
     
         5 . The mattress of  claim 1  further comprising a third layer comprising an indentation load deflection that is different than the first indentation load deflection. 
     
     
         6 . The mattress of  claim 5  wherein the third layer encloses the core. 
     
     
         7 . The mattress of  claim 5  wherein the third layer comprises an indentation load deflection that exceeds the indentation load deflection of the first indentation load deflection. 
     
     
         8 . The mattress of  claim 1  wherein the first polyhedral foam layer and the second polyhedral foam layer are removed from the same piece of foam material. 
     
     
         9 . A method of making a mattress, comprising:
 transversely sectioning a piece of foam material to form a first polyhedral foam piece and a second polyhedral foam piece, each of the first and second polyhedral foam pieces providing a first and a second polyhedral foam layer comprising a first indentation load deflection, a longitudinal planar first surface, and a longitudinal convoluted second surface opposite to said. first planar surface; and,   joining said first planar surface of said first polyhedral foam layer to the first planar surface of said second polyhedral foam layer.   
     
     
         10 . The method of  claim 9  further comprising applying a third layer comprising an ILD different than the first ILD to the longitudinal convoluted surface of said first polyhedral foam layer and to said longitudinal convoluted surface of the second polyhedral foam layer thereby forming said mattress. 
     
     
         11 . The method of  claim 10  wherein said third layer comprises a quilted fabric.
