1. A method of producing a skin-covered foamed plastic article, comprising by steps:

  • (a) preparing a bag-shaped skin member which consists of two parts, the two parts having respective inwardly projected peripheral portitions stitched up, one of said peripheral portions being folded back fully to constitute a thicker peripheral portion;

    (b) preparing a mold which has a cavity formed therein, said cavity having at its wall an elongate ridge thereby to define a groove at a given portion of said cavity;

    (c) putting said skin member in said cavity in such a manner that said thicker peripheral portion is forcedly received in said groove;

    (d) pouring a liquid material of foamed plastic into the bag-shaped skin member in the mold;

    (e) inserting a shaping die into said cavity;

    (f) putting a lid member on said mold thereby to close said cavity; and

    (g) removing, upon sufficient hardening of the material, said lid member and said shaping die and taking out a hardened product of foamed plastic from the mold.
