Abstract A decorative button for use in the surface of an automotive seat and method for making same are disclosed. In the method, a button core member is set on the back side of a trim cover assembly comprising a top cover member, a wadding and a wadding cover, and the button core member is covered by a reinforcing member. The peripheries of the button core member are then pressed and heated to weld the top cover member, wadding, wadding cover and reinforcing member around the button core member to one another into an integral body and, at the same time, to form a deep-valley-shaped recessed portion in the surface of the top cover member around the button core member.
