A headrest comprising:
- first and second headrest pillars;
- a stationary unit disposed between the first and second headrest pillars;
- a movable unit movable apart from or close to the stationary unit toward a front or rear direction;
- an X linkage connecting the stationary unit to the movable unit, the X linkage including an inside linkage segment and an outside linkage segment rotatably connected each other at a central connecting intersection;
- and
- a front-rear locking mechanism comprising at least one lock receiver and at least one locking component engageable with the lock receiver, the locking mechanism being configured to lock or unlock the movable unit movable relative to the stationary unit toward the front or rear direction, wherein
- the stationary unit has at least one clearance to receive that at least one lock receiver, and
- the at least one lock receiver protrudes rearward from the stationary unit through the clearance in response to the movement of the movable unit toward the rear direction.
