A properly adjusted head restraint reduces whiplash injury risk in rear-end crashes by 24% to 44%, and the correct position is level with the top of your head and as close as one finger’s thickness behind it.
Most drivers never touch their headrest after buying the car, a mistake that can turn a fender bender into a years-long neck injury. The device is a head restraint, not a comfort cushion — it limits backward head movement during a rear-impact crash. Getting the height, distance, and angle right takes about ten seconds and could save you from whiplash even at low speeds.
What’s the Correct Headrest Position?
The top of the head restraint should be level with the top of your head — at minimum, no lower than the middle of the back of your head. The horizontal gap between the back of your head and the restraint should be as small as possible, ideally within 2 inches or about one finger’s thickness. The restraint must align with the back of your head (behind your eyes and ears), not with your neck. Less space is better; the restraint should contact your head first, not your neck.
If the headrest forces your head forward when properly positioned, adjust the seatback angle slightly rather than tilting the restraint backward. Modern head restraints are designed with a forward tilt to reduce the gap — never force them flat if they’re spring-loaded.
How to Adjust Your Headrest Step by Step
Raising the head restraint is straightforward — pull it upward until it clicks into position. To lower it, press the release button (at the base or on one side of the post) and push down until it locks into the nearest notch.
For four-way adjustable head restraints in Ford and Lincoln models, pull the restraint all the way forward to reset it, then pull it forward again to the desired angle until you hear a click. Some Lincoln models require pressing both the adjust/release button and the unlock/remove button simultaneously to remove the headrest entirely.
For rear seat head restraints in vehicles like Alpine cars, tilt the bench seat forward, insert the support rods into the guide holes, and push fully down until it locks. Never occupy a rear seat with the headrest in its lowest storage position — it provides no crash protection there.
After any adjustment, verify the head restraint is locked by pulling up firmly. A loose restraint can fail during a crash and cause severe injury.
Common Headrest Mistakes That Increase Injury Risk
- Incorrect height — setting the top below the middle of the back of your head leaves your neck exposed to whiplash forces.
- Excessive gap — more than 2 inches of space allows your head to snap backward before the restraint engages, reducing effectiveness by a large margin.
- Neck alignment — positioning the restraint behind your neck rather than your head transfers force to a more vulnerable area first.
- Assuming no adjustment is needed — every driver and passenger has a different height and seating position. Each person should adjust their own restraint before the car moves.
If you find the correct position uncomfortable, adjust your seat height or seatback angle first rather than misaligning the headrest. If you’re looking for a headrest designed for relaxation rather than crash safety — for a massage or lying down — our roundup of the best bed massage headrests covers the top-rated options for comfort and support.
| Adjustment | Correct Setting | Common Mistake |
|---|---|---|
| Height | Top level with top of head | Restraint too low, exposing neck |
| Distance | Within 2 inches (one finger’s thickness) | Gap too large, head snaps back |
| Alignment | Behind the head (eyes/ears) | Behind the neck instead |
| Angle (4-way models) | Tilted slightly forward | Forcing restraint flat |
| Lock | Check by pulling up firmly | Leaving it loose or unlatched |
Legal and insurance note: In the US — Texas being one clearly enforced example — removing or driving without safety equipment the vehicle was built with can lead to legal or insurance complications after a crash. Headrests are legally expected to remain installed and functional if the vehicle came with them. If your head restraint is missing or damaged, replace it before driving.
FAQs
Can I remove the rear headrests for better visibility?
You can remove rear head restraints when the seats are unoccupied, but every occupied seat must have its restraint properly positioned. Never drive with a passenger in a seat whose headrest is fully folded or removed — it provides no whiplash protection in that position.
Why does my headrest push my head forward?
That forward tilt is intentional — it reduces the distance between your head and the restraint so the device engages sooner during a crash. Instead of tilting the restraint backward, try adjusting your seatback angle or raising the seat height to find a comfortable position that still maintains protection.
Do all cars have adjustable head restraints?
Nearly all modern passenger vehicles built with integrated head restraints offer height adjustment, and many offer tilt adjustment as well. Luxury models like Lincoln sometimes include audio speakers inside the headrest, which prevents removal. Check your owner’s manual for the specific adjustment mechanism in your vehicle.
