PROBLEM TO BE SOLVED: To provide a method for molding a fiber cushion body excellent in durability, and further to provide the fiber cushion body and a seat for a vehicle by using the fiber cushion body. SOLUTION: This fiber cushion body is the one shaped by using an opened raw stock including a binder fiber with the low softening point, and/or a nonwoven fabric obtained by chipping a strand as an essential components. The molding method comprises (1) a step for charging the interior of a mold with the opened raw stock, and/or the nonwoven fabric obtained by chipping the strand, and heating the charged materials to the softening temperature of the binder fiber or more while holding materials in a volume larger than the volume of a required shape of the objective fiber cushion body to previously mold the materials, (2) a step for cooling the heated material to the temperature under the softening point of the binder fiber, compressing the cooled material to the volume smaller than the volume of the required shape, and hardening the material as it is to promote the crystallization of the bound surface of the fibers in the fiber web or the nonwoven fabric, and (3) a step for opening the mold.
