A headrest assembly may include a first frame member operatively connected to a seat, a second frame member that is selectively movable with respect to the first frame member, and a locking mechanism for use in adjusting the first locking member between a first locked condition that prevents the second frame member from moving relative to the first frame member and a second adjustable condition that permits the second frame member to move relative to the first frame member.
