ABSTRACT:
Disclosed are pocketed upholstery springs in strip form characterized by placement of the closing seam midway between the ends of the springs of the strip, with the marginal flaps of the pocket strip fabric outwardly of the closing seam folded over as a two-ply belt and incorporated into the cross seams which define the pockets about the springs. Adjacent rows of such strips are joined together by tacking through their respective belts at the cross seams to form two-row modules for ease of mattress/cushion assembly, or to form full-size mattress/cushion constructions by joining row upon row.
