This invention provides a method for producing a cushion structure having excellent quality in a short time by the final heat-molding of a fiber aggregate containing binder fibers by compression molding a fiber aggregate in multiple stages leaving the thermal shrinkage margin, passing hot gas through a by-pass channel on the side wall part of the molded article to eliminate the problem of insufficient heating of the side face of the molded article and detecting the completion of the filling of the fiber aggregate into the mold cavity by the pressure variation in the mold cavity. |
