Integrally molded polyurethane foam products that are free of bubbles formed from the gas evolved during foaming of foaming materials, that do not allow the foaming materials to exudate and that have surfaces with adequate gas permeability and soft to the touch, giving sufficient satisfaction at use, being free of stuffy and other unpleasant feelings to the touch. The present invention also relates to an integrally molded polyurethane foam product comprising a skin member that is formed into a desired form by sewing and a polyurethane foam that is made by foaming a foaming material being poured into said skin member, in which the skin member is made by laminating a fabric and a synthetic resin film and is provided with 5 to 100 through holes per cm.sup.2 in a diameter of 0.01 to 0.3 mm. The foaming pressure of the polyurethane material used in the production of these integrally molded polyurethane foam products is preferably 0.5 to 2.0 kg/cm.sup.2.
An integrally molded polyurethane foam product comprising a skin member formed into the shape of said foam product by sewing and polyurethane foam that is formed by depositing or pouring a liquid foaming material into said skin member and foaming, wherein said skin member is made by laminating a fabric and a synthetic resin film and is provided with 5 to 100 per cm.sup.2 of through holes in a diameter of 0.01 to 0.03 mm.
An integrally molded polyurethane foam product comprising a skin member formed into the shape of said foam product by sewing and polyurethane foam that is formed by depositing or pouring a liquid foaming material into said skin member and foaming, wherein said skin member is made by laminating a fabric and a synthetic resin film, said synthetic resin film having an uneven surface on the back side of the surface laminated with said fabric, and part of or all of caves in said uneven surface are provided with holes having a diameter of 0.1 to 0.3 mm.
An integrally molded polyurethane foam product comprising a skin member and a polyurethane foam, in which said skin member is composed of a fabric with a backcoating that backs one side surface of said fabric, and the gas permeability of said skin member is 0.01 to 1.0 cm.sup.3 /cm.sup.2 /sec and said backcoating and said polyurethane foam are joined directly.
