The 2022 Toyota Sienna is a capable two-car-seat vehicle without being a frictionless one. It does not fit three car seats across, in the second-row captain's chairs Cars.com tested.
Fit grades from Cars.com's Car Seat Check, conducted by certified child passenger safety technicians. Seat dimensions are the manufacturers' published figures for the products we carry. Which seats we recommend, and why, is our own editorial judgment, from the catalog we stock and fit in person in Sumner, WA.
Which car seats we would put in a 2022 Toyota Sienna
These picks are shaped by what the fit check actually found here: the head restraint has to move before a seat sits flush; the buckles are hard for a child to work unaided. Widths are the widest published figure the manufacturer gives. Stock and pricing as of 2026-08-04. We stock 17 car seats with a published width, so the same names recur across our guides; the ordering and the reasoning are what differ.
The picks above are chosen on width, which is what decides whether another seat or an adult fits beside them. The measured width and depth of every car seat we carry is published in one place, so you can check our reasoning against your own measurements.
The grades at a glance
| Test | Grade |
|---|---|
| LATCH | A |
| Infant seat | A |
| Rear-facing convertible | A |
| Forward-facing convertible | A |
| Booster, second row | A |
| LATCH, third row | A |
| Forward-facing convertible, third row | A |
| Booster, third row | B |
| Third-row entry | B |
Where the anchors are
Second row: two sets, exposed for easy access. Third row: two sets in the outboard positions, also exposed.
Two halfway down the second-row seatback, clearly marked. Three atop the third-row seatback, also clearly marked.
Installing an infant seat
Went in easily on Toyota's extra-long-slide chairs, and the 5-foot-6-inch front passenger had tons of legroom with the seat installed behind them.
Installing a convertible
Same story: easy install, ample front passenger legroom.
An A in both the second and third rows.
Boosters and the buckle-yourself years
Second row is an A, with stable buckles kids should manage alone. The third row drops to a B: the head restraint flops down but does not come out, and only the passenger-side buckle is stable, with the other two sitting flush with the cushion.
Check your vehicle manual before moving or removing a head restraint. Not every restraint is designed to come out, and where one is removed the seating position still has to give your child head support to the top of the ears, either from the vehicle seat back or from the car seat itself.
The third row
The second-row seats can be cumbersome to move, but they collapse with a bit of muscle and open a wide passage. Cars.com notes that collapsing them will not work with a car seat installed, which is the situation most families reading this are actually in.
Three car seats across
No. 2022 Toyota Sienna does not take three car seats across. If a third seat is coming, the deciding factor is whether the second row is a bench or captain's chairs, not the size of the vehicle. Our three-across guide covers which vehicles do, and which seat combinations fit them.
Which strollers suit a large cargo area
Space is not your constraint. Buy the stroller that suits how you actually use it.

| Stroller | Folded (L x W x H) | Price |
|---|---|---|
| Silver Cross Reef 2 Multi-Terrain Modular Stroller | 19.0" x 23.5" x 29.0" | $1,200 |
| Maxi-Cosi Fame Modular Stroller | 30.93" x 24.51" x 15.76" | $1,000 |
| Romer Tura Stroller | 38.5" x 18.5" x 22.25" | $950 |
| Bumbleride Era Full-Size Reversible Stroller | 31.5" x 24.0" x 13.0" | $949 |
| Veer Switch&Roll Stroller | 15.0" x 25.5" x 36.0" | $949 |
| UPPAbaby Vista V3 Stroller | 17.3" x 25.7" x 33.3" | $900 |
| Veer Switch&Jog | 19.0" x 27.0" x 35.0" | $899 |
| Bumbleride Indie All-Terrain Stroller | 31.5" x 24.5" x 13.0" | $799 |
Compare every stroller side by side.
Four things that apply whatever you drive
Lower anchors have a weight limit, and it is lower than most parents expect. NHTSA advises against using the lower anchors once the combined weight of your child and the car seat reaches 65 pounds. Your seat's label or manual gives the maximum child weight for lower-anchor use; where it does not, subtract the seat's own weight from 65. Past that point the seat belt install is the correct one, and it is no less safe.
Use the top tether on every forward-facing install. NHTSA recommends it whether the seat is installed with the lower anchors or the seat belt, as long as both the car seat manufacturer and the vehicle manufacturer permit it. Check your car seat's tether weight limit too, and stop using the tether once your child exceeds it even while they still fit the seat.
Do not borrow outboard lower anchors for the center seat. Unless your vehicle manual specifically says the center position may use the inner anchors from the two outboard positions, it may not. Where the center has no anchors of its own, install there with the seat belt.
Rear-facing for as long as the seat allows. Keep your child rear-facing until they reach the height or weight maximum of their convertible seat, not until a birthday. Our guides to how long to stay rear-facing, LATCH versus the seat belt and booster readiness cover each of these properly.

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 performed by Certified Child Passenger Safety Technicians. 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 by a Certified Child Passenger Safety Technician (CPST). If you are near Sumner, Washington, a fit check and install help come with every car seat we sell.
Which seats we recommend on a given vehicle is our own editorial judgment, formed from 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.
