ABSTRACT:
In a method of manufacturing a permeable seat cushion, a permeable fabric material is pressed between a pair of dies while being heated and wetted with steam to render the fabric temporarily unpermeable to provide a seat covering of bag-like structure. A first precut filler pad is bonded to the seat covering, and a second precut filler pad is then bonded to the first filler pad. A frame is mounted together with springs and other necessary elements on the thus obtained assembly, and the seat covering is anchored at its pheripheral edges to the frame to complete the seat cushion.
