The object of acquiring easy ways of washing and replacing of {TAIL ~ the objects} described above can be achieved by separating a main headrest body of {HEAD ~ a cushionlike mass} of soft material from a rigid headrest base in such a manner that the main headrest body further comprises an interior member and a surface cover and that both the member and the cover are made integral and inseparable or are made separable so as to bring only those members of the headrest body necessary for replacement or washing into a detachable relation with respect to the headrest base
