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.

A method of disassembling a pocketed spring assembly, the method comprising:
- providing a pocketed spring assembly having a dimensionally stabilizing substrate secured to one of top and bottom surfaces of the pocketed spring assembly and a scrim sheet secured to the other of the top and bottom surfaces of the pocketed spring assembly, said pocketed spring assembly comprises a plurality of parallel strings of springs joined together, each of said strings comprising a plurality of individually pocketed springs, each of said strings comprising a piece of fabric joined along a longitudinal seam, first and second opposed plies of fabric being on opposite sides of the springs, a plurality of pockets being formed along a length of said string by transverse seams joining said first and second plies, at least one spring being positioned in each said pockets, said dimensionally stabilizing substrate being thicker than the scrim sheet and more rigid than the scrim sheet;
- and
- pulling the dimensionally stabilizing substrate and the scrim sheet away from each other to tear the strings along perforations in the piece of fabric.
A method of disassembling a pocketed spring assembly, the method comprising:
- providing a pocketed spring assembly having a dimensionally stabilizing substrate secured to one of top and bottom surfaces of the pocketed spring assembly and a scrim sheet secured to the other of the top and bottom surfaces of the pocketed spring assembly, said pocketed spring assembly comprises a plurality of parallel strings of springs joined together, each of said strings comprising a plurality of individually pocketed springs, each of said strings comprising a piece of fabric joined along a longitudinal seam, first and second opposed plies of fabric being on opposite sides of the springs, a plurality of pockets being formed along a length of said string by transverse seams joining said first and second plies, at least one spring being positioned in each said pockets, said dimensionally stabilizing substrate being thicker than the scrim sheet and more rigid than the scrim sheet;
- and
- tearing each of the strings along perforations in the piece of fabric to separate the springs from the fabric.

- grasping the dimensionally stabilizing substrate with one hand and the scrim sheet with the other hand;
- and
- tearing each of the strings along perforations in the piece of fabric to separate the springs from the fabric.
