ABSTRACT:
A method of manufacturing a pocketed coil spring assembly comprising vertically spacing two sheets of fabric apart so that the sheets are generally parallel to one another. The sheets are then attached together along one end edge and rows of coil springs are inserted between the sheets. After each row of coil springs is inserted between the sheets, the sheets are attached together along transversely extending lines of attachment in alternative planes of the pocketed coil spring assembly. These steps of inserting rows of coil springs and attaching the sheets together in alternative planes occurs sequentially until an appropriate length of the assembly is obtained.
