Abstract: A seat is prepared by molding a synthetic resin foaming material integrally with a frame structure embedded therein. The frame structure includes an upper line frame extending along the upper outer periphery of the seat, a lower line frame connected to the upper line frame and supporting springs for resiliently supporting the upper line frame from below against the load of an occupant.
