ABSTRACT:
A body support member for spacing a body above a supporting structure which comprises a sheet of resilient plastic material permanently deformed to produce downwardly disposed, laterally spaced, elongated protuberances distributed over a body support area for engaging the supporting surface, adjacent elongated protuberances being complementary in shape with each one having a plurality of reversed direction portions along its length, the reversed direction portions in adjacent protuberances being in overlapping relation in the plane of the body support area looking in the direction the elongated protuberances extend, whereby the body support area of the member will resist flexing along all straight lines traversing the body support area. The body support area is surrounded by a marginal portion including a raised bead and in the instant form of the invention the elongated protuberances stop short of the bead to present a marginal ledge or narrow shelf which can be utilized to hold a flat, decorative cover sheet by sewing or the like to the ledge. In such case the cover sheet resides in recessed relation to the bead with no portion of the plastic sheet material overlying the decorative cover, thereby enhancing the overall appearance of the covered body support member while reducing its cost. In a modification the decorative cover overlies and holds a cushion pad in place.
