Mazda CX-9 Car Seat Compatibility & Safety Review

Overview: Family-Focused Performance Meets Safety

The Mazda CX-9 remains one of the top-performing three-row SUVs for families, not only due to its dynamic driving capabilities but also because of its thoughtful interior layout and car seat readiness. In this comprehensive guide, we delve into how the CX-9 fares when tested with a variety of child car seats in different seating positions, especially focusing on the Latch system, space, and ease of use across both second and third rows.

Second-Row Car Seat Performance

Booster Seat – Grade: A

When positioned in the second row, the booster seat fits securely and comfortably. The adjustable head restraints ensure proper alignment, and the seat belt buckles are mounted on firm stalks, allowing children to buckle themselves in with ease.

Rear-Facing Convertible – Grade: B

This seat fits well without compromising legroom for front-row passengers. However, accessing the lower Latch anchors requires some maneuvering due to their recessed placement. Despite this, installation is solid once connected.

Forward-Facing Convertible – Grade: B

The convertible seat performs well when installed forward-facing. The head restraint can be raised to accommodate the seat properly. While the top tether anchor is easy to find and secure, the lower Latch anchors again present a bit of a challenge.

Infant Car Seat – Grade: B

Installing the infant seat is relatively straightforward, though it does require effort to connect to the lower anchors. The seat fits comfortably behind a shorter front passenger without affecting comfort.

Latch Accessibility – Grade: B

Two sets of lower anchors are present but recessed beneath upholstery flaps, making them less accessible than ideal. On a positive note, the top tether anchors are clearly visible and easy to use.

Third-Row Car Seat Access & Performance

Booster Seat – Grade: A

Surprisingly accommodating, the third row allows for a snug booster seat fit thanks to a slim, fixed head restraint that doesn't interfere with the seat’s back. Buckles are sturdy and within easy reach for older children.

Forward-Facing Convertible – Grade: A

Although the third row lacks lower Latch anchors, it does feature one clearly marked top tether anchor on the passenger side. Installation via the seat belt is straightforward, and the fixed head restraint doesn’t compromise fit.

Third-Row Access – Grade: B

Accessing the third row is made possible by a second-row bench that slides and folds with ease. However, when car seats are installed on both outboard sides, entry becomes a challenge—sometimes requiring access through the cargo area.

Three Across? CX-9’s Capacity for Multiple Car Seats

Fitting three car seats across the second row is a mixed experience. While space is sufficient, the middle seat’s narrowness can limit options. We attempted a configuration with a forward-facing convertible in the center, flanked by a booster and an infant seat. This setup technically fit, but buckling the booster was difficult, especially for a child attempting it independently.

Important Installation Tips for Parents

• Parents can install seats using either the Latch system or a seatbelt.
• The Latch system is only approved for use up to a combined child and seat weight of 65 pounds.
• Ensure the top tether is properly secured when using a forward-facing seat, especially in the third row.
• Always check the vehicle’s owner manual and the car seat manual to verify compatibility and installation techniques.

Child Safety Seats Used in Our Review

To evaluate real-world performance, the following seats were tested:

• Graco SnugRide Classic Connect 30 (Infant Seat)
• Britax Marathon (Convertible Seat)
• Graco TurboBooster (Booster Seat)

Front seats were adjusted to simulate a 6-foot-tall driver and a shorter front passenger. This provided a realistic environment to assess how car seats impact space and comfort for adult passengers.

Final Verdict: Mazda CX-9 Offers Solid Safety & Usability

Overall, the Mazda CX-9 proves to be a reliable and practical choice for families prioritizing safety and versatility. While its lower Latch anchor access could be improved, its performance in fitting car seats—especially in the third row—is impressive. The ease of accessing tether anchors, combined with a comfortable and family-friendly design, make the CX-9 a strong contender in the competitive midsize SUV segment.
