2024-2025 Mazda CX-90 3rd Row Headrests: The Fixed Headrest and Car Seat Problem
This guide covers the critical issue of the non-removable outboard third-row headrests, their impact on child car seat installation, and options for replacement.
- The biggest issue is that the two outboard 3rd-row headrests are fixed and cannot be removed, causing major interference with child car seats.
- Only the center headrest (on 3-seat configurations) is removable via a standard push-button release.
- Failure is almost always cosmetic (torn leather, collapsed foam). There are no common mechanical or electrical failures.
- When buying used, verify the exact color (Black, Greige, White) and condition, as a used OEM part is a cost-effective replacement for damage.
Known Issues: The Fixed Outboard Headrest Dilemma
The single most important issue for owners of the 2024-2025 Mazda CX-90 is the design of the third-row headrests. While the center headrest is removable, the two outboard (side) headrests are integrated into the seat structure. They can be folded forward to allow the seat to lay flat, but they are not designed to be removed by the owner.
Warning: The outboard third-row headrests are not user-removable. Attempting to forcibly remove them will likely damage the seat upholstery and the headrest mechanism.
Fixed Headrests and Child Car Seat Interference
This non-removable design creates a significant problem when installing many types of forward-facing child car seats and high-back booster seats. For a car seat to be installed safely, its back must sit flush against the vehicle's seatback. The CX-90's protruding third-row headrests prevent this, creating a dangerous gap between the two.
- Car Seat Fitment Issues: Professional car seat safety checks have consistently given the CX-90's third row a low grade for forward-facing convertible and booster seats due to this interference.
- Owner's Manual Confirmation: The owner's manual even specifies an exception for this location, stating to always remove headrests when installing a child seat *except* for the third-row outboard seats, implicitly acknowledging they cannot be removed.
- Tether Routing: The fixed headrest also complicates the routing of the top tether strap on some car seats, which is a critical connection for preventing head excursion in a crash. 🎬 Watch: Detailed breakdown of CX-90 car seat setup
This design flaw is a major consideration for families who plan to use the third row for children in forward-facing or booster seats.
Symptoms of a Damaged Headrest
Since the headrests have no electronic or complex mechanical parts, 'failure' is limited to physical damage. Look for:
- Torn or Scuffed Leather: Check for rips, deep scratches, or discoloration from sun exposure or spills. This is the most common reason for replacement.
- Collapsed Foam: The internal foam can break down over time or from impact, making the headrest feel flat or lumpy.
- Sticking Fold Mechanism (Outboard): The mechanism that allows the outboard headrests to fold forward could potentially jam, though this is not a widely reported issue.
- Damaged Posts (Center): On the removable center headrest, check that the metal posts are straight and free of damage. Bent posts can make the headrest difficult or impossible to install or adjust.
Buying a Used 3rd Row Leather Headrest Set
Purchasing a used headrest is a great way to replace a damaged one without paying high dealership prices. Since these parts don't 'wear out' mechanically, a used OEM headrest in good condition is functionally identical to a new one.
What to Inspect:
- Verify the Color: The CX-90 was offered with several interior colors, including Black, Greige, and White leather. Ensure the part you are buying is an exact match. An eBay listing might describe a part as 'Black (kh1)' for example.
- Check for Cosmetic Flaws: Carefully examine photos for any tears, stains, deep scuffs, or sun fading. Pay close attention to the seams.
- Confirm the Position: If buying a single headrest, ensure it's the correct one. The center headrest has two posts and is removable. The outboard headrests are integrated into the seatback and are not sold as simple, standalone parts. You are likely buying the entire seat back assembly if you need to replace an outboard one.
- Ask About the Donor Vehicle: Inquire about the mileage of the vehicle the part came from. While not a major factor for a headrest, lower mileage parts have seen less use and sun exposure.
Replacement Information
Installation difficulty varies dramatically depending on the headrest's position.
Center Headrest Replacement
- Difficulty: 1 out of 5
- Time: Less than 5 minutes
- Procedure: To remove the old headrest, press and hold the small release button on the plastic guide at the base of one of the metal posts and pull the headrest straight up. To install the new one, simply insert the posts into the guides and push down until it clicks into place.
Outboard Headrest Replacement
Professional Installation Recommended: The outboard headrests are not designed for user replacement. Replacing one requires disassembling the seat, including removing the upholstery (seat cover). This is a complex job that should be left to a professional auto upholsterer or technician.
- Difficulty: 5 out of 5
- Time: 2+ hours
- Procedure: Involves removing the seatback panel, detaching the leather upholstery clips and listings, accessing the internal headrest mounting points, and then reassembling everything without causing wrinkles or damage.

Frequently Asked Questions (FAQ)
Can I remove the 2024-2025 Mazda CX-90 third-row headrests?
You can only remove the center headrest on 3-seat configurations. The two outboard (side) headrests are fixed and not designed to be removed by the user; they only fold forward.
Why won't my child's car seat fit properly in the third row?
The fixed, non-removable outboard headrests protrude forward, preventing most forward-facing and high-back booster seats from sitting flush against the seatback. This creates an unsafe gap and is a widely-noted compatibility issue with this vehicle.
🎬 See a real-world child seat installation walkthroughAre there any recalls for the CX-90 headrests?
No. As of mid-2024, there are no specific recalls or Technical Service Bulletins (TSBs) for the third-row headrests on the 2024-2025 Mazda CX-90.
Can I buy just one headrest?
Yes, you can typically purchase single headrests, especially on the used market. This is common for replacing a single damaged unit. Be sure to specify whether you need the removable center headrest or an outboard one, which would be part of a larger seat back assembly.
