ABSTRACT:
Disclosed is a method of making a seat-like object comprising a leather touch surface layer and a urethane cushion body stuck together. It uses a weld sheet intervening between the surface layer and the cushion body in place of application of an adhesive substance to the surface layer and the cushion body. The weld sheet when heated above its melting temperature, will weld and stick the surface layer and the cushion body together, maintaining the leather touch over the whole surface area of the product, still allowing air to pass in or out.
