2. Description of the Related Art A skin of an automobile seat or the like is made of a cushion body made of a foam (for example, urethane foam or the like) in which a plurality of pieces of the skin cut into a predetermined shape are joined together, and the joined seam is covered with the skin. It is housed in a concave groove on the surface.

[0004] Therefore, the seam allowance at the seam joint is thick and rigid. The skin is adhered to the cushion body by applying tension so as not to cause wrinkles and tarls on the surface of the cushion body. Also, the seam allowance at the seam joint is accommodated in the concave groove so that the seam allowance does not appear as a convex portion on the surface.
