A device for fastening a headrest to a backrest of a vehicle seat comprises first and second guide units for receiving first and second headrest columns. First and second receiving units fixed on the backrest receive sleeve-like portions of the first and second guide units. The second guide unit comprises a locking mechanism for locking various vertical positions of the second headrest column relative to the second guide unit. At least one rib is arranged on an outer lateral surface of each sleeve-like portion. At least one recess, in which the rib of the respective guide unit engages in a positive locking manner, is arranged on each receiving unit. A width of the rib of the first guide unit is greater than a width of the recess of the second receiving unit.

A seat assembly is provided with a seat back support member with a primary substrate received upon an upper cross member and a pair of side members of a seat back frame to support a back of an occupant. A pair of receptacles is formed through the primary substrate to receive a pair of posts that extend from the upper cross member of the seat back frame. A secondary substrate extends from the primary substrate to support a head of the occupant. A method of assembling a seat assembly determines whether the seat assembly comprises one of an adjustable head restraint assembly and an integrated head restraint. The adjustable head restraint assembly is assembled upon the pair of posts in response or a seat back support member with a pair of apertures formed therethrough is assembled upon the upper cross member with the pair of posts received in the pair of apertures.
