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.

A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have springs of different gauge wire and some of the pockets of the strings having springs of different gauge wire are spliced together. At least some of the strings have springs of different geometries and some of the pockets of the strings having springs of different geometries are spliced together. At least some strings may have end sections with springs different than a middle section therebetween, the springs of the end sections being firmer than the springs of the middle section.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. Each string is joined to at least one adjacent string. Each string comprises one piece of fabric joined to itself to create first and second opposed plies on opposite side of coil springs. The plies are joined by transverse seams to form a plurality of pockets along a length of the string. At least one spring is positioned in each of the pockets. The piece of fabric is a non-woven ultrasonically weldable fabric made with fiber made with at least some used or recycled material or content.

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.
