A method of producing a skin-covered foamed plastic article, which includes preparing a lower mold which has a cavity formed therein; putting a bag-shaped outer skin member into the cavity, the skin member having a porous inner layer; pouring a foamable material for the foamed plastic article into the bag-shaped outer skin member; and adjusting a pressure which is created in the cavity due to foaming of the foamable material.

A method of producing a skin-covered foamed plastic article, comprising: (a) preparing a lower mold which has a cavity formed therein; (b) putting a bag-shaped outer skin member into said cavity, said skin member having a porous inner layer; (c) sealingly closing said cavity; (d) pouring a foamable material for the foamed plastic article into the bag-shaped outer skin member, said material being capable of impregnating a portion of said inner layer, said material foaming in said cavity and causing pressure in said cavity to gradually increase; (e) curing said material to provide said article; and (f) activating pressure control means when said pressure increases to a predetermined value and thereby adjusting said pressure such that said curing is carried out under a certain pressure which will provide said inner layer with a material-impregnated part of a desired thickness therethroughout.
