Abstract: A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

Abstract: A unitary wire chair is disclosed for supporting concrete reinforcing rebar or the like above a supporting surface onto which concrete is poured. The unitary wire chair is so constructed such that it may be snapped or otherwise secured onto the rebar or other concrete reinforcing element and retained thereon without the use of any tie wire or other attachment devices.

Abstract: An innerspring structure for a mattress comprises a row of outer coils formed from a continuous piece of wire with the coils interconnected with interconnection segments and a row of inner coils similarly formed. The interconnection segments of the coils form coil heads for pairs of adjacent coils and each head includes a first linear portion disposed generally parallel to the row. The row of inner coils is positioned together and generally coaxially with the row of outer coils for forming reinforced coil units. A helical lacing structure winds around portions of the inner and outer coils to couple the coils together into reinforced coil units and the first linear portions of the coils are configured for being captured with at least approximately three loops of the helical lacing structure for forming a row of reinforced coil units.
