Abstract
An internal cushion element is constructed in the form of a box. It has a top wall, bottom wall, and side walls to define an internal cavity. A plurality of spaced vertical foam spacer slabs are positioned in the cavity extending from the front of the box to the back of the box, and from the bottom of the box to the top of the box. The strips are spaced apart in generally parallel rows. The relaxed state height of at least some of the strips is higher than that of the outside walls. Thus, the internal strips provide a crown to the cushion element. A convoluted foam patch is also provided on the outside of the cushion element.
