A method is described for forming an armrest comprising a three-dimensional box-like trim cover assembly having slit and holes formed therein, a frame, and a shaft separate from the frame. The frame is inserted through the slit into the inside of the trim cover assembly, and then, the shaft is inserted through one hole into the trim cover assembly. The shaft is connected to the frame at a predetermined position within the trim cover assembly via a connecting element. Thereafter, this incomplete armrest unit is subject to foaming in a foaming die, to thereby form a complete armrest. The trim cover assembly includes a high-density foam layer and an impregnation preventing film having ventilation holes formed therein in order to prevent impregnation of liquid foaming material into a foam wadding layer of the trim cover assembly and attained air permeability of the armrest.
