Abstract
Herein disclosed is a method of producing a skin-covered foamed polyurethane article, such as a seatback proper of an automotive seat, a seat cushion proper of the same or the like. A bag-shaped skin member which is to constitute the skin of the article consists of two parts which have respective inwardly projected peripheral portions stitched up. One of the peripheral portions is folded back fully to constitute a thicker peripheral portion. A mold used for molding the article has a groove which extends around the side wall of the cavity. The skin member is put into the cavity of the mold in such a manner that the thicker portion is forcedly received in the groove, and then a liquid material of polyurethane is poured into the bag-shaped skin member.
