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 lines traversing the body support area. Where desired, the resiliency of the plastic material of the body support member can be such that the reversed direction portions of the elongated protuberances incorporate an inherent spring-like action under the weight of a supported body to cushion the same. Ornamental cover material may be applied over the top and/or bottom of the body support member. The body support member is so designed that it can be vacuum or pressure molded and is therefore stackable in large numbers for shipment and storage. The body support member may have joined to the lower portions of the elongated protuberances a second sheet of plastic material which is flat or a second sheet of plastic material which has upwardly disposed elongated protuberances which can be complementary in shape to the elongated protuberances of the body support member joined to the lower portions of the downwardly disposed elongated protuberances of the body support member.

A supporting spacing member for use between a supporting surface and a body to be supported comprising a sheet of resilient plastic material having an upper surface and a lower surface, a body support area provided by the sheet of plastic material, a plurality of spaced elongated protuberances permanently formed in the sheet of plastic material throughout the body support area and extending downwardly from the upper surface, the elongated protuberances being open at the top and having side walls and bottom walls, the plurality of elongated protuberances being disposed in spaced adjacent relation to one another and extending longitudinally continuously along paths which extend across an entire dimension of the body support area, portions of the sheet of plastic material which extend between the open tops of spaced adjacent elongated protuberances coacting to form in the aggregate a generally flat body engaging structure, the lowermost surfaces of the bottom walls of protuberances coacting to form in the aggregate a generally flat support structure for engaging the supporting surface, each of the plurality of elongated protuberances incorporating along its longitudinal dimension a plurality of curved direction changing portions and a plurality of portions connecting the curved direction changing portions, successive curved direction changing portions of elongated protuberances alternating in the direction of change along the paths across the body support area, alternate curved direction changing portions of spaced adjacent elongated protuberances along the paths across the body support area being in overlapping relation to each other looking in the direction the paths extend, the disposition of elongated protuberances in paths across an entire dimension of the body support area and the overlapping relationship of the alternate curved direction changing portions resulting in a body support area in which all planes normal to the generally flat body engaging structure will successively intersect a plurality of elongated protuberances at a plurality of spaced points across an entire dimension of the body support area or will repeatedly intersect alternately disposed portions connecting curved direction changing portions of a single elongated protuberance at a plurality of spaced points across an entire dimension of the body support area.
