A foam mattress having a crown area with cored-out areas therein to modify the harshness of feel of said mattress.

DETAILED DESCRIPTION What is claimed is: 1.
A molded foam mattress of essentially a rectangular shape and having a crown, said crown being divided into a decorative segment by cored-out areas, said coring being positioned to give a geometric pattern of grooves that extend continuously in lengths no more than 4 inches before the grooves terminate or change directions to give raised portions relative to the groove, each portion being capable of being compressed independent of any other portion for at least 10 percent of its compression deflection.
2.
The foam mattress of claim 1 wherein the depth of the cored-out area varies from about 0.
5 to about 2 inches to give areas whose raised portions have a controlled degree of compression.
3.
The foam mattress core of claim 1 wherein the geometric pattern is hexagonal.
4.
The foam mattress core of claim 1 wherein the cored-out areas in the crown extend no closer than one inch of each edge of the core to leave an uncored strip adjacent each edge.
5.
The foam mattress core of claim 1 wherein the geometric pattern is formed by curved members to leave raised portions inside said curved members.
6.
The foam mattress core of claim 1 wherein the geometric pattern extends across the core on a bias to each edge.




Description:
This invention relates generally to a cushion.
More particularly, it relates to a high comfort mattress having a smartly tailored look.
The foam rubber or plastic cushion generally has a foam core with a cover thereon or enclosed therein.
These foam rubber or plastic cushions and especially those made from polyurethane foam have a feeling of hardness when the load is low, such as when the cushion is first encountered by the body.
Thus, when sitting down or lying down on such a cushion or mattress, the occupant has the sensation of first encountering a hard shell and then suddenly breaking through.
This sensation can be varied by changing the density of the foam but this effects the comfort factor after the initial encounter
