2020-2023 Mazda CX-9 Headrest: Bench Seat vs. Captain's Chair Guide
Your definitive guide to identifying the correct second-row headrest for your CX-9 and avoiding the common bench-seat-versus-captain's-chair compatibility trap.
- The most critical issue is compatibility: second-row headrests for bench seats and captain's chairs are NOT interchangeable.
- A major safety recall (NHTSA 21V-750) affects the second-row bench seat on 2020-2021 models; verify it has been performed.
- Many owners find the forward-angled design uncomfortable, but this is an intentional safety feature to prevent whiplash, not a defect.
- Replacement is extremely easy, requires no tools, and can be done in under two minutes.
Key Compatibility Warning: Bench Seat vs. Captain's Chairs
Warning: The single most important factor when purchasing a replacement second-row headrest for a 2020-2023 Mazda CX-9 is the seating configuration. Headrests for the three-person bench seat are NOT interchangeable with headrests for the two-person captain's chairs. They use different part numbers, have different designs, and will not fit properly in the wrong seat type.
Starting with the 2020 model year, Mazda offered second-row captain's chairs as an option on higher trim levels, moving away from the bench-seat-only configuration of previous years. Always verify which seating your vehicle has before ordering a part.
Second-Row Seating Variants (2020-2023)
- Sport Trim: Typically equipped with a standard second-row bench seat for 7-passenger capacity.
- Touring Trim: Comes standard with a bench seat, but captain's chairs were available as part of the Touring Premium Package.
- Touring Plus Trim: Second-row captain's chairs became standard on this trim.
- Grand Touring Trim: Offered a choice between a heated bench seat or heated captain's chairs.
- Carbon Edition & Signature Trims: These premium trims come standard with second-row captain's chairs.
Symptoms of Failure
Unlike complex mechanical parts, headrest failure is typically straightforward and visible. There are no associated fault codes.
- Physical Damage: The most common issue is damage to the upholstery, such as tears, rips, stains, or collapsed foam from wear and tear or sun exposure.
- Adjustment Mechanism Failure: The button or latch that allows for height adjustment can break or become stuck. This may leave the headrest stuck in one position or unable to lock in place. A TSB for older models noted that excessive force could damage the internal lock mechanism.
- Rattling: A loose or damaged headrest may rattle or vibrate within the seat guides, especially over rough roads.
Known Issues & Owner Complaints
Uncomfortable Forward Angle
A widespread complaint across many CX-9 model years is the forward-jutting angle of the front and rear headrests. Owners report that the headrest pushes their head uncomfortably forward, leading to neck strain on long drives. This is not a defect, but a deliberate safety design intended to reduce the gap between the head and the restraint to minimize whiplash in a collision. Some owners resort to flipping the headrest backward, but this is not recommended as it defeats the safety feature and may not lock in place.
Related Recalls and Service Bulletins
Safety Recall NHTSA 21V-750 (Mazda Recall 5221I): This critical recall affects 2020-2021 Mazda CX-9 models equipped with the 60/40 split-bench second-row seat. The seat could slide forward during a collision, increasing the risk of injury. Vehicles with captain's chairs are not affected by this recall. Before purchasing, ensure any applicable recalls have been performed by a Mazda dealer.
Technical Service Bulletin (TSB) 09-026/17
While this TSB applies to the third-row headrests on older 2016-2017 CX-9s, it is worth noting. It addresses an issue where the headrest lock mechanism could be damaged by excessive force, preventing it from locking in the upright position. This highlights the importance of not applying undue force to any headrest in the vehicle.
Buying a Used Headrest: What to Check
A used OEM headrest is an excellent, cost-effective option. Because they are not a moving part, they have a long lifespan. Follow this checklist to ensure you get a quality part.
- Confirm Seating Configuration: This is the most critical step. Get the part number from the seller and match it to your vehicle's needs (bench or captain's chair). If a part number is unavailable, ask the seller for a photo of the seat it came from.
- Inspect Upholstery: Carefully check the photos for any tears, deep scratches, or significant discoloration in the leather or cloth. Pay attention to the stitching to ensure it is intact.
- Check Foam Integrity: Ask the seller if the foam is still firm and has not collapsed. The headrest should feel solid, not soft and mushy.
- Examine the Posts: Ensure the two metal posts are straight and free of rust or damage. Bent posts may not slide correctly into the seat guides.
- Verify the Adjustment Latch: If possible, ask the seller to confirm that the height adjustment button works correctly.

Frequently Asked Questions (FAQ)
Can I use a headrest from a captain's chair on my bench seat?
No. The headrests are not interchangeable between the two different seating types. The mounting points and potentially the post-spacing are different. You must buy the specific headrest designed for your seat configuration.
Why does the headrest push my head forward?
This is a deliberate safety design to minimize the distance your head can travel backward in a rear-end collision, which helps prevent whiplash. While uncomfortable for some, it is a critical safety feature.
How do I remove the second-row headrest?
Press and hold the small plastic button located at the base of one of the headrest's metal posts on the top of the seatback. While holding the button, pull the headrest upward.
Is the front seat headrest the same as the second-row headrest?
No. The front and second-row headrests have different designs and part numbers. They are not interchangeable.
