In the production of a pocket spring assembly for cushion or mattress, two layers of fabric are secured together along multiple parallel seam zones so as to form a quilt defining a plurality of parallel fabric tubes, the tubes so formed are supported on guides extending longitudinally through the tubes, portions of the quilt are repeatedly drawn from the guides at their one ends and folds formed in each layer of fabric in the drawn off portion are secured to form pockets from the drawn off portions of the quilt, and precompressed coil springs (10) are passed through the guides (41-72) and released into the pockets between each drawing of the quilt, with their axes perpendicular to both the axes of the fabric tubes and the direction of advancement of the quilt, so that secured folds in the fabric of the tubes in front of and behind the released springs retain them in the packets. Spaced longitudinal slits are formed in the seam zones, the slits permitting the fabric to envelope the tubes.
