Abstract: A supporting surface provided by utilizing a plurality of individual sections which when joined will provide a planar supporting surface and which sections include formed outer skins having a plurality of supporting post sections formed integrally with the skins and extending from the upper skin surface to the lower skin surface thus providing a void between the skins which may be filled with material to provide additional strengthening for the sections. The formed sections include a stepped interlocking feature for joining the sections and the sections are designed to permit a selection of joining arrangements to provide a supporting surface of various configurations. The surfaces may include non-slip characteristics formed integrally with the sections during the molding process.
