The 2025 Toyota Grand Highlander handles most of the car seat years, but the third-row forward-facing convertible is a real weak point at C. Cars.com's tested three-seat combination did not fit across the second row of the 2024 Toyota Grand Highlander with captain's chairs. Cars.com's grades: A for LATCH, the infant seat, the rear-facing convertible and the third-row LATCH; B for the forward-facing convertible, the second-row booster and the third-row entry; C for the third-row forward-facing convertible and the third-row booster.
Fit grades from Cars.com's Car Seat Check, conducted by Cars.com editors, including a certified car seat technician. Cars.com's check was written about the 2024 Toyota Grand Highlander; Cars.com says little has changed for 2025.
Car seats we carry, and what to check in the Toyota Grand Highlander
These are the seats we carry, grouped by your child's stage. We have not tried them in a Toyota Grand Highlander ourselves. Under the list are the points from Cars.com's check worth confirming first.

Convertible seats
Booster
What to check in your Toyota Grand Highlander
- A low grade to read first. Cars.com graded the third-row forward-facing convertible C in the Toyota Grand Highlander. Read that section of this guide before you choose a seat for that stage.
- Which second row you have. Cars.com tested the Toyota Grand Highlander with second-row captain's chairs, so its three-across answer covers that configuration only. Three-across shoppers should see which cars fit three car seats.
- Booster buckles. Cars.com graded the third-row booster C and noted buckles a child may find hard to work alone. Test the buckle with your child in the seat position you plan to use.
- Third-row head restraints. Cars.com found the third row's fixed head restraints in the way of its convertible and booster; in the second row it removed the restraint before each fit well. Check the seat sits flush at the position you plan to use.

The grades at a glance
| Test | Grade |
|---|---|
| LATCH | A |
| Infant seat | A |
| Rear-facing convertible | A |
| Forward-facing convertible | B |
| Booster, second row | B |
| LATCH, third row | A |
| Forward-facing convertible, third row | C |
| Booster, third row | C |
| Third-row entry | B |
Where the anchors are
Lower anchors. Second row: two sets, exposed for easy access. Third row: one set on the passenger side, in slits in the seat and easy to use.
Top tether anchors. Two in the second row, clearly marked but buried in the seatback carpet. Two more in the third row on the passenger side and middle seatbacks, also marked and also buried.
Installing an infant seat
LATCH connection was easy and the 5-foot-6-inch front passenger had ample legroom.
Installing a convertible
The rear-facing convertible installed without problems, and front passenger legroom was not affected.
A B in the second row and a C in the third, where the fixed head restraint is in the way.
Boosters and the buckle-yourself years
The booster fit in the second row once Cars.com removed the head restraint, though Cars.com notes the floppy buckles could make it difficult for kids to buckle up on their own. The third row is a C: the fixed head restraint pushes the booster off the seatback when it should sit flush against it, and the buckles sink into pockets, complicating access and use. Cars.com says the third-row middle seat is not a great place for the booster either: the booster is wider than that seat's cushion, so it rides over the buckle and takes up seat space from the riders on either side, and that seat's buckle comes down from the ceiling, blocking the driver's rear view when in use.
Check your vehicle manual before removing or adjusting a head restraint: not every restraint is designed to come out. Your car seat manual says what the seat needs from the vehicle seat behind it.
The third row
LATCH grades an A, but both the convertible and the booster drop to a C because of the fixed head restraints. Cars.com says the middle seat's seat belt comes down from the ceiling, and there is not enough room there for the convertible. The second-row seats tilt and slide forward with ease for a path to the third row, but they cannot be tilted with a car seat installed.
Three car seats across
Cars.com's tested three-seat combination did not fit across the second row of the 2024 Toyota Grand Highlander with captain's chairs. Our three-across guide can help you plan which exact seat and vehicle configurations to check.

Educational information only. This guide is for general education. It is not professional, medical, legal, or safety advice, and it does not create any advisory or professional relationship between you and SugarBabies. You are responsible for the safe selection, installation, and use of any car seat.
How a car seat fits and installs depends on your exact vehicle (its model year, trim, and seating configuration) and your exact car seat model. The instructions that came with your car seat and your vehicle owner’s manual always control. If anything in this article ever conflicts with those instructions, or with current guidance from the National Highway Traffic Safety Administration (NHTSA), follow the manufacturer instructions, your vehicle manual, and NHTSA, not this article.
Vehicle fit grades are compiled from third-party sources, including independent car seat fit testing by Cars.com editors, among them a certified car seat technician. Product dimensions are the manufacturer’s published figures for the items we stock, and are the widest published measurement where more than one is given. Any combination total is simple arithmetic with no allowance for shell overlap, and is a shortlist to check rather than a guarantee of fit. Specifications, model years, configurations, pricing and stock change, and we do not guarantee the accuracy, completeness, or current status of any of it. This article does not replace a hands-on check of your own installation against those instructions.
Which seats we list on a given vehicle is our own editorial choice from the seats we carry, informed by those published dimensions and those third-party fit findings. It is not the result of testing that seat in that vehicle, and we have not verified any combination of seats side by side in any vehicle on this page. Buckle position, belt-path interference between neighboring seats and recline angle all affect real-world fit and none of them are captured by a width measurement.
