How Do Car Seats Fit in a 2019 Toyota Sienna?

The 2019 Toyota Sienna excels at hauling a large family and all their stuff, and that includes kids in car seats, which often take up a lot of space. For this Car Seat Check, we tested an all-wheel-drive SE Premium model with second-row captain’s chairs, and all of our car seats had ample space. The Sienna is also available with a second-row bench that increases its occupancy to eight.

Solid

  • Latch, grade A: In the second row, the captain’s chairs’ two sets of lower anchors sit about 1.5 inches into the seat bight, but the leather seat cushions move out of the way fairly easily. There are two top tethers at the base of the seatbacks; their position makes them easy to miss.
  • Infant, grade A: This car seat installed easily after reclining the Sienna’s seat to expose the Latch anchors. The 5-foot, 6-inch-tall front passenger had plenty of legroom.
  • Rear-facing convertible, grade A: Again, we had no installation or fit issues.
  • Booster, grade A: After removing the head restraint in the second row, the booster fit well. The seat belt buckles are on stable bases, which should make them easier for kids to grasp.
  • Third-row entry, grade A: The second-row seats fold up and slide forward to create a roomy walkway to the third row. The space between the captain’s chairs is also wide enough for an adult to scoot through.
  • Third-row forward-facing convertible, grade A: Installation was easy thanks to accessible Latch anchors. We had no trouble finding and using the top tether anchors in the third row.

So-So

  • Forward-facing convertible, grade B: In the second row, this seat was easy to install and fit well after we removed the head restraint, but it lost a grade because the top tether anchor is so far down the seatback that it’s easy to overlook.
  • Third-row Latch, grade B: The third row’s bench seat has two sets of lower anchors. One is in the outboard side; the other awkwardly straddles the two remaining seats, taking up the two seating positions. The two top tethers in the third row are well-marked and easy to use.
  • Third-row booster, grade B: The booster fits well in the third row, and the seatback reclines for a better fit. The seat belt buckles in the middle and one outboard position have floppy buckles, which could make them tough for kids to grasp and use. The other outboard seat has a stable buckle.

Grading Scale

Solid indicates an A grade for optimum ease of use and fit. So-So indicates B or C grades for one to two ease-of-use or fit issues. Skip It indicates D or F grades.

B: One room, fit or connection issue. Some problems accessing third row when available.

C: Marginal room plus one fit or connection issue. Difficult to access third row when available.

D: Insufficient room, plus multiple fit or connection issues.

F: Does not fit or is unsafe.

About Cars.com’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.
