A plurality of support beams extend on inner surfaces of the parts and at least along the outer perimeters and inner straight sides of each part. Each side beam has at least one locking bore and the locking bores are coaxial when the planar member is in the use condition to receive a locking pin to lock the use condition in place. A plurality of legs are movably connected to the planar member for supporting the planar member above a floor in the use condition.
