Pocketed spring assembly having dimensionally stabilizing substrate
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.

Low density pocket spring mattress with integrated cushioning pads
A pocket spring mattress for use in a bedding or seating product is disclosed. The mattress comprises a plurality of interconnected coil springs enclosed in continuous covers forming strings of pockets accommodating the coil springs. Adjacent coil springs within each string are spaced apart by an interjacent separation distance, said separation distance exceeding at least 20 percent of the diameter of the largest one of the spiral turns of the adjacent coil springs. Further, the pocket spring mattress further comprises a cushioning pad located above the upper end of each coil spring, wherein the covers provides first compartments enclosing the coil springs, and second compartments enclosing the cushioning pads, said first and second compartments being separated from each other. The cushioning pads each have a length extension in the longitudinal direction of the strings exceeding the diameter of the largest one of the spiral turns of the corresponding coil spring.
