Abstract
A method of forming cushions by needle punching is demonstrated in which superior structural integrity is achieved without adhesives or other external fasteners. The process is economical and utilizes polyurethane foam which is mechanically bound by needle punching to various polymeric fibers. In an alternate embodiment of the process, the needle punching causes the fibers to penetrate the foam block at an angle to the vertical for greater mechanical bonding between the fiber layer and the foam block. The cushion so formed by the various processes can be covered or upholstered as needed for furniture seating and other purposes.
