Multiple zone layered mattress

Abstract

This disclosure addresses mattresses. In particular, a mattress that includes a plurality of layers. A foam core of the mattress is constructed to have selected characteristics of support and cushioning, the characteristics varying from zone to zone of the mattress. The foam core includes at least three zones; a first zone corresponding generally to an area that supports the head of a user, a second zone corresponding generally to an area that supports the torso of the user, and a third zone corresponding generally to an area that supports the legs and feet of the user. A top surface of the foam core is formed with a plurality of parallel transverse peaks.

What is claimed is: 
     
         1 . A mattress device, comprising:
 a plurality of layers, the layers being chosen from various cushioning and absorbent materials, the layers being one or more of coil springs, fill material, foam, gel, and fiber; and   a mattress cover to enclose and secure the layers; wherein   at least one layer is a foam core, the foam core comprising a plurality of zones, each of the zones being constructed to have selected characteristics of support and cushioning, the characteristics varying from zone to zone.   
     
     
         2 . The mattress of  claim 1 , wherein:
 the foam core is a latex foam rubber pad.   
     
     
         3 . The mattress of  claim 1 , wherein:
 a top surface of the foam core comprises a plurality of transverse peaks.   
     
     
         4 . The mattress of  claim 3 , wherein:
 the transverse peaks are parallel.   
     
     
         5 . The mattress of  claim 3 , wherein:
 the transverse peaks are generally triangular in cross section.   
     
     
         6 . The mattress of  claim 1 , wherein:
 a top surface of the foam core includes multiple cutouts.   
     
     
         7 . The mattress of  claim 1 , wherein:
 the foam core comprises at least three zones; a first zone corresponding generally to an area that supports the head of a user, a second zone corresponding generally to an area that supports the torso of the user, and a third zone corresponding generally to an area that supports the legs and feet of the user.   
     
     
         8 . The mattress of  claim 7 , wherein:
 a top surface of the foam core comprises a plurality of transverse peaks, the transverse peaks being spaced more closely together in the second zone as compared to the transverse peaks in the first and third zones.   
     
     
         9 . A foam core adapted to be used in a mattress, comprising:
 a plurality of zones, each of the zones being constructed to have selected characteristics of support and cushioning, the characteristics varying from zone to zone, the zones comprising a first zone corresponding generally to an area that supports the head of a user, a second zone corresponding generally to an area that supports the torso of the user, and a third zone corresponding generally to an area that supports the legs and feet of the user.   
     
     
         10 . The mattress of  claim 9 , wherein:
 a top surface of the foam core comprises a plurality of transverse peaks, the transverse peaks being spaced more closely together in the second zone as compared to the transverse peaks in the first and third zones.   
     
     
         11 . The mattress of  claim 9 , wherein:
 the foam core is a latex foam rubber pad.   
     
     
         12 . The mattress of  claim 9 , wherein:
 a top surface of the foam core comprises a plurality of transverse peaks.   
     
     
         13 . The mattress of  claim 12 , wherein:
 the transverse peaks are parallel.   
     
     
         14 . The mattress of  claim 12 , wherein:
 the transverse peaks are generally triangular in cross section.   
     
     
         15 . The mattress of  claim 9 , wherein:
 a top surface of the foam core includes multiple cutouts.
