Yes, you can fit 3 car seats in a Chevy Trax, but it is a very tight fit and requires careful selection of the car seats. The 2024 Chevy Trax has three sets of LATCH anchors (Lower Anchors and Tethers for CHildren) across the rear seat, which is a good start. However, the vehicle's overall interior width is the main limiting factor.
The key is using narrow, compact car seats. Standard, wide models will not fit three-across. You'll need to look for seats specifically designed for this purpose, often called "three-across" or "slim" car seats. The installation process can be challenging, and you will likely need to use the vehicle's seat belts for at least one of the installations, as the dedicated LATCH anchors might not align perfectly when three seats are side-by-side.
Here is a comparison of the Chevy Trax's rear seat specs against some competitors known for better family-friendly space:
| Vehicle Model | Rear Shoulder Room (Width) | Rear Hip Room | Easiest 3-Car Seat Fit? | Key Consideration |
|---|---|---|---|---|
| Chevy Trax | 53.8 inches | 50.0 inches | Challenging | Requires narrow, "3-across" specific car seats. |
| Honda CR-V | 55.5 inches | 55.3 inches | Moderate | More forgiving width than Trax. |
| Kia Seltos | 53.7 inches | 51.1 inches | Challenging | Similar narrow fit to the Trax. |
| Toyota RAV4 | 56.0 inches | 47.7 inches | Easier | Wider shoulder room provides more flexibility. |
| Subaru Forester | 56.0 inches | 52.7 inches | Easier | One of the best in class for cabin width. |
Before you commit, the absolute best practice is to take your actual car seats to the dealership and attempt the installation yourself. This hands-on test is the only way to be 100% certain they will fit securely and without excessive compression.

We tried it with our Trax last month. It’s possible, but just barely. We had to buy two new, super-slim booster seats to go next to our infant’s rear-facing seat. The hardest part was buckling the seatbelt for the middle kid—my hand barely fit between the seats. It works for school runs, but I wouldn’t want to take a long road trip like that. Go to the store and test your exact seats before you buy the car.
