ÄObjectsÜ To provide a seat which is covered with a surface material and has a multilayer with different hardness, the air permeability, a good feeling on the surface and such a hardness that a weight of a person can be supported. ÄMeans for solving ProblemsÜ The seat (1) is covered with a surface material (2) having the air permeability and comprises a foamed body having an outline generally corresponding to an outline of the seat. The foamed body comprises a first foamed body (10) as a base of the foamed body and a second foamed body (6). The second foamed body (6) is resulted in one with a back surface of the surface material and is also resulted in one with a front surface of the first foamed body by: injecting and laminating a liquid foamable mixture on the front surface of the first foamed body and then by pressing and compressing the laminated liquid foamable mixture in the first foamed body and a pressure applying mold having a molding surface and positioned on the surface material on the laminated liquid foamable mixture and simultaneously sucking through a suction slot provided in the pressure applying mold, when the laminated liquid foamable mixture has completed a gas reaction thereof but is still in a flowing condition. <IMAGE> |
