ABSTRACT:
A method of making a crowned cushion element is provided. The method includes the steps of forming a foam pan of a bottom and side walls of foam pieces, positioning foam slabs therein in which at least one of the slabs has a greater relaxed height than the side walls, and then adhering a top onto the foam slabs to form the cushion. The slabs are positioned within the foam pan in such a manner that they remain separated from one another when under normal compression by a user seated on the cushion. Also, the at least one slab having the greater relaxed height than the side walls also has a relaxed height greater than the width of the slab along a direction transverse to the elongate direction on either the face of the slab in contact with the top piece or the face in contact with the bottom piece of the cushion element.
