Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
A resilient structure for placement on a bed or chair to provide a cushion for the human body; said structure comprising, a cover including a moisture impervious upper member and moisture impervious side members merging into said upper member, a bottom member of a permeable nature attached to said side members, a seam joining said side members to said bottom member, strap means attached to said side members and adapted to pass below a portion of the bed or chair and provided with closure means, and a filler comprised of discrete randomly foam pieces of oriented elongate differing shapes, said pieces each having multiple elongate surfaces, some of said surfaces of each piece being slightly curved along one axis, angular edges defining said multiple surfaces, said elongate surface being of a fibrous nature to promote cohesion of the pieces to one another and resist packing of same.
Claim 2
Dependent Claim
