A mold for manufacturing a skin covered foamed plastic seat capable of structually preventing the leakage of the liquid foam resin from a space between the skin cover and the bossings provided on the mold for the holes to be made on it. The mold includes a lower mold over which a sink cover is to be placed, having a protruded portion to be inserted into a hole on the skin cover corresponding to a hole to be made on the skin covered foamed plastic seat, the protruded portion having a circumference smaller than that of the hole on the skin cover, and the upper mold to be assembled with the lower mold, having a bossing for making the hole to be made on the skin covered foamed plastic seat, the bossing having a concavity to be engaged with the protruded portion of the lower mold at a bottom, and a circumference larger than that of the hole on the skin cover.
