How Do Car Seats Fit in a 2019 Lexus GX 460?

The Lexus GX 460 is capable when it comes to towing and off-roading, but Lexus’ large three-row SUV misses the mark when it comes to interior space for car seats. In our Car Seat Check of the GX 460, we tested a model with second-row captain’s chairs that had entertainment-system screens embedded into the front seatbacks, impacting second-row legroom. And although the GX 460’s third row is roomier than the new Lexus RX 350L’s, it’s not by much.

  • Latch, grade A: The two sets of lower anchors sit under a large Velcro flap for easy access and connection. Two top tether anchors sit three-quarters of the way down the seatback. They’re set in the upholstery and require some fishing to find and use.
  • Booster, grade A: After removing the head restraint, the booster fit well. The SUV’s large, stable buckles should make it easy for kids to buckle up independently.
  • Third-row booster, grade A: The head restraint doesn’t interfere with how the booster sits on the seatback and the buckles are on stable stalks, which should make them easier for kids to grasp and use.


  • Infant seat, grade C: This seat was easy to install, but the video screen mounted on the front seatback takes up a lot of space, and we had to move the front passenger seat far forward to fit the infant seat. The 5-foot, 6-inch-tall front passenger’s knees were almost touching the dash.
  • Rear-facing convertible, grade C: This seat was also easy to install, but we had the same second-row room issues we experienced with the infant car seat.
  • Forward-facing convertible, grade B: After removing the head restraint, this seat fit well. Connecting to the lower latch anchor was easy, but finding and connecting to the top tether anchor was more challenging since the anchor is buried in the upholstery on the seatback.
  • Third-row access, grade C: The opening is narrow and the step-in is high.
  • Third-row forward-facing convertible, grade B: There are no lower anchors in the third row and only one top tether anchor, on the passenger side. We used the seat belt to install the forward-facing convertible, and it fit well; the fixed head restraint is small enough not to interfere with how the convertible rested on the seatback. As with the second row, the top tether anchor was not very visible.

About’s Car Seat Checks

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

For the Car Seat Check, we use a Graco SnugRide Classic Connect 30 infant-safety seat, a Britax Marathon 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.’s Editorial department is your source for automotive news and reviews.
