Abstract
A skin covered foamed plastic article capable of providing improved softness, feel and comfortableness by reducing the amount of penetration of the liquid foam resin into the skin cover with a thin wadding. The article includes a wadding to be attached on a back side of the surface skin and to make a direct contact with the pad member, having a soft layer contacting the surface skin and a hard layer contacting the pad member which has a constant thickness and is made to be harder than both the soft layer and the pad member.
