成形不良が発生する不具合がある。However, in such seat cushion bodies, although the slab urethane piece or chip urethane piece is impregnated with the foamable urethane raw material, it is extremely difficult to adjust the amount of impregnation. Not only does this form a hard impregnated layer on the surface, causing discomfort when sitting on the seat, but the air contained in the slab urethane piece or chip urethane piece is replaced with the impregnated foamable urethane raw material, and the foamable urethane material is removed during foam molding. There is a problem that air is released into the raw material and causes molding defects due to air pockets.
