Abstract
Engineered foam components for mattresses reduce tension forces in the foam and in the horizontal plane or block planar pieces, and improve the conformance and motion separation characteristics of foam support systems. The tension relief foam pad is a generally rectangular piece of foam having a top surface and a bottom surface. The length and width measurements of engineered foam pieces are substantially equal to that of a mattress with which it is to be used. Depending on the arrangement of the tension relief foam pad within the mattress construction, either the top or bottom surface contains a plurality of continuous cuts, slits or openings arranged in a checkerboard or other patterns with an opposite planar uncut surface.
