How Do Car Seats Fit in a 2024 Rivian R1T?

The verdict: By nature, pickup trucks are obviously good at hauling stuff, but what about people? We put the all-electric Rivian R1T to the test for this Car Seat Check and found that it easily accommodates two car seats thanks to no-nonsense lower anchors and ample backseat legroom. We struggled with the placement of the truck’s top tether anchors for our forward-facing convertible car seat, however.

Does it fit three car seats? No.

Take a look at how the Latch system and each car seat scored below in our Car Seat Check of the 2024 Rivian R1T.

Latch: Grade A

The two lower sets of lower anchors sit just within the seat bight, where the back and bottom cushions meet. They’re not quite completely exposed, but connection was still easy. The three top tether anchors sit on a narrow metal shelf behind the head restraint, and they’re tough to access because they’re right behind the head restraint.

Infant Seat: Grade A

Installation was easy, and the 5-foot-6-inch front passenger had plenty of legroom in front of it.

Rear-Facing Convertible: Grade A

As with the infant seat, installation was uncomplicated and front passenger legroom was not impacted.

Forward-Facing Convertible: Grade C

We struggled to install the convertible in forward mode for a couple of reasons. First, the R1T’s fixed head restraint pushed the convertible off of the seatback, and it should sit flush against it. Second, it was tough to access the top tether anchor because it sits on a narrow shelf directly behind the head restraint. The truck’s owner’s manual says to go over the head restraint if the car seat has a single tether strap and around if it has a double strap. Our convertible’s single strap setup was tough to connect because it’s difficult to see the tether anchor behind the head restraint and hard to tighten it since it’s such a short distance.

Caregivers could install the convertible seat in the middle position because there’s no head restraint there. However, it’s still tough to get a taut fit with the tether strap because the distance from the car seat to the tether anchor is so close.

Booster Seat: Grade B

The R1T has tall, stable buckles, which should be easy for kids to grasp and use independently. The truck’s fixed head restraint pushed the booster off of the seatback, however, and it should sit flush against it.

About’s Car Seat Checks

Editors Jennifer Geiger and Jennifer Newman are certified child safety seat installation technicians.

For the Car Seat Check, we use a Chicco KeyFit 30 infant-safety seat, a Graco Contender 65 convertible seat and Graco TurboBooster seat. The front seats are adjusted for a 6-foot driver and a shorter passenger. The three child seats are installed in the second row. The booster seat sits behind the driver’s seat, and the infant and convertible seats are installed behind the front passenger seat.

We also install the forward-facing convertible in the second row’s middle seat with the booster and infant seat in the outboard seats to see if three car seats will fit; a child sitting in the booster seat must be able to reach the seat belt buckle. If there’s a third row, we install the booster seat and a forward-facing convertible. Learn more about how we conduct our Car Seat Checks.

Parents should also remember that they can use the Latch system or a seat belt to install a car seat, and that Latch anchors have a weight limit of 65 pounds, including the weight of the child and the weight of the seat itself.
