Yes, you can fit three car seats across the third row of a Durango, but it requires careful planning and specific types of seats. The key is the vehicle's width and the design of its LATCH system anchors. The Durango's third row has a claimed hip room of 49.1 inches, which is adequate but not overly spacious for three seats side-by-side.
The most significant challenge is the LATCH system configuration. The Durango typically has two sets of lower LATCH anchors in the third row, positioned for the two outboard seats. The middle seating position usually lacks dedicated lower anchors, meaning you will need to use the vehicle's seat belt to secure the center car seat. This is a perfectly safe method when done correctly, but it can be more cumbersome than using the LATCH system.
To maximize your chances of success, opt for narrow-profile car seats. Some models are specifically designed to be narrower to facilitate three-across installations. You will likely need to use the seat belt for at least one seat, and it's often easiest to install the seat in the center position first. Be prepared for a tight fit where the seats may touch or press against each other; this is acceptable as long as each seat is independently tightly installed and does not rely on the others for stability.
| Vehicle/Seat Consideration | Specification / Recommendation | Notes |
|---|---|---|
| Dodge Durango 3rd Row Hip Room | 49.1 inches | Provides the physical space for three seats. |
| LATCH Anchors (3rd Row) | 2 sets (Outboard positions only) | Center seat must use seat belt for installation. |
| Recommended Car Seat Type | Narrow-profile convertible or booster | Models like Diono Radian 3R or Clek Fllo are popular choices. |
| Installation Method | Combination of LATCH and seat belt | Test for independent tightness (less than 1 inch of movement at the belt path). |
| Critical Step | Always consult both vehicle and car seat manuals. | Rules for spacing and installation can vary. |
The most reliable way to confirm a safe configuration is to perform a test fit with your specific car seats before committing. If possible, seek assistance from a certified Child Passenger Safety Technician (CPST) who can help you achieve a safe and secure installation for all three seats.

We did it in our 2021 Durango, but it was a puzzle. We used two Diono Radians and a Graco SlimFit. The trick was installing the center seat with the seat belt before buckling the ones with LATCH on the sides. The seats are definitely touching, but each one is rock solid on its own. It’s tight, but it works for our triplets. The hardest part is actually buckling the kids in with such limited space to reach.

As a technician, I see this often. The Durango's third-row width is sufficient, but the LATCH anchor placement is the main constraint. You must use the seat belt for the center seat. Focus on seats with a narrow base. The installation isn't difficult, but it requires patience to ensure each seat doesn't compromise the of its neighbor. A successful fit means less than one inch of movement at each seat's belt path when tested independently.

Honestly, while it's technically possible, think about daily use. Climbing back to the third row to buckle three kids in that tight space is a chore. If you need three car seats regularly, a minivan with wider sliding doors and more room in the second row is a far more practical long-term solution. The Durango works for occasional use, but for every day? It will test your patience.

I focused on the measurements. The hip room is about 49 inches, so you need car seats that each measure less than 17 inches wide at their base. I researched models known for three-across fits. The Clek Fllo is 17 inches wide, the Diono Radian 3R is about 16.5 inches. With the right models, the math checks out. Just be sure to account for the contour of the vehicle seats, which can make the effective space slightly smaller than the raw number suggests.
