Abstract: A nestably stackable bedding foundation assembly which replaces the traditional border wire and disposed coil spring foundation assembly in a so-called box spring. The nestably stackable foundation assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. A bedding foundation comprises a rectangular base, a nestably stackable bedding foundation assembly fixedly attached atop the base, and spring means disposed between and connected to the base and the nestably stackable assembly.

Abstract: A spring cushion structure with a plurality of hour-glass shaped spring coils arranged in columns and rows with adjacent springs within a row connected at the top and bottom by a helical wire extending between adjacent columns and with the marginal coils attached at the top to a border wire extending around the assembly. A transparent sheet is placed between the bottoms of the assembly and support sinuous wires which are bent to provide an upwardly extending integral suspending arm and bent again to provide an outwardly extending shepherd hook shaped attachment arm which is attached to a wood frame surrounding the periphery of the entire structure.

Abstract: A spring assembly of the kind comprising a rigid base frame, a wire grid frame, a plurality of helically-coiled springs attached at one end to the base frame and at their other ends to the wire of the grid frame, said wires and ends of the coils being so structured as to enable detachably attaching the ends of the coils to the wires of the grid frame in overlapping locking engagement with the wires of the grid frame without the aid of wire clips or the like.
