Abstract
The invention is a unitary space frame that has utility as a box spring frame and can be injection molded in a simple two-piece mold comprising an offset grid space frame having two grids similar in geometry with one grid offset from the other in plan said grids connected by connecting members that are parallel to the direction of mold opening travel and that interconnect angularly askewed members of said grids.
