A method of molding a headrest of automotive seat comprises the following steps. First, a bag shaped flexible outer skin member is prepared, has an elongate slit formed therethrough. A part of a stay member is inserted into the outer skin member through the slit and set relative to the outer skin member. A given biasing force is applied to longitudinal ends of the slit so that the slit is stretched in longitudinally opposed directions and thus caused to take a closed position. Then, an injection nozzle of a foamable material feeder is put into the slit by expanding the slit against the biasing force. A foamable material is poured into the outer skin member, and the material feeding is stopped when a given amount of material is fed to the outer skin member. The application of the biasing force to the slit is continued until the material is sufficiently cured.

A cushion structure of seat has a major holding part constructed of foamed polyurethane. A wadding is applied to a front surface of the major holding part. The wadding is constructed of down and feather which are bound with a binder. The major holding part and the wadding which are thus united are put in a bag-shaped outer skin.

A method of producing a feather containing resilient body to be used for a padding or a trim cover of a vehicular seat. The method is as follows: First, a predetermined amount of feathers is coated with water and prepolymer of polyurethane resin. The coated feathers are put into a mold to form a mass of feathers. In the mold, the feather mass is adjusted in thickness and heated so that the polyurethane resin prepolymer is hardened.
