ABSTRACT:
A resilient article includes an enclosure extending about a filler material of resilient foam pieces. The pieces have multiple, distinct surfaces defined by angular edges with the surfaces and edges of adjacent pieces cooperating to inhibit movement between the pieces to prevent packing which would utlimately cause a reduction in the resiliency of the article.
