ABSTRACT:
A position adjustable headrest includes a bag-shaped outer skin member defining an inside space thereof. The outer skin member has first inwardly-bent end portions which are opposed to and in abutment with each other. The first inwardly-bent end portions define a first slit therebetween. The outer skin member has second and third slits formed therethrough which are opposed to each other and extend from longitudinally opposed ends of the first slit. A pad member made of plastic is covered by the outer skin member. The plastic is foamed and cured in the inside space so as to fill the inside space with the plastic and to press the first inwardly-bent end portions against each other, thereby closing the first slit tightly to prevent the plastic from leaking out through the first slit. Two stays project outwardly through the second and third slits respectively.
