MEMBRANE COVERED CUSHION HAVING INDENTED PATTERN AND METHOD FOR MAKING SAME Abstract of the Disclosure A cushion usable as a seat or back-rest in a seat for a vehicle or as an article of furniture has an indented design, which is ornamental or functional or both, formed in its outer exposed surface. The cushion comprises a resilient compressible deformable body, such as a polyurethane foam block, which has the indented design formed in a surface thereof, and further comprises a flexible stretchable membrane, either of cloth or plastic, which covers the body surface, follows the contours of the indented design and is adhesively secured thereto. The cushion is manufactured by providing a preformed body having the design indentations formed therein; providing a flexible stretchable membrane heated and having an adhesive on one side thereof; and providing a fixture having a die cavity generally conforming in size and shape to the body but including projections which correspond in shape to but are of greater height than the design indentations in the body. The membrane, which is heated to about 250° to 300° F, and then the body are inserted into the die cavity and the body is physically forced thereinto as by means of a weighted platten. This causes the fixture projections and overlying membrane to penetrate deeply into the indented design in the body. After several minutes, cooling occurs, the membrane takes a set and the adhesive cures to cause good adhesion, and the finished cushion is then removed from the die cavity.
