ABSTRACT:
An innerspring assembly comprising a plurality of strips of pocketed coil springs, each including axially interconnected spring pockets having a pocket height. The strips of pocketed coil springs are comprised of overlapping plies of material adjoined together by axially offset cross seams extending generally along the pocket height to define the spring pockets, with each spring pocket containing a coil spring. In one embodiment, the overlapping plies of at least two strips are coupled together by connecting seams extending along the pocket height and axially offset from the cross seams. In another embodiment, the overlapping plies of at least three strips are interconnected. In another embodiment, overlapping edges of the plies of material are adjoined by a closing weld seam positioned adjacent an end surface of the pocketed coil springs, with the overlapping plies of material of at least two strips interconnected by connecting welds positioned along the pocket height.
