Car seats we carry, and what to check in the Subaru Trailseeker
In the Subaru Trailseeker the booster result is the one to read closely, so we start there. We have not tested them in a Subaru Trailseeker. After the list is what Cars.com's findings say to check in this vehicle before you buy.

What to check in your Subaru Trailseeker
- Booster buckles. Cars.com graded the booster B and noted buckles a child may find hard to work alone. Have your child try the buckle at the seat they will use.
- Head restraints. Cars.com removed a head restraint so a seat could sit flush. Your vehicle manual says how yours adjusts.

The grades at a glance
| Test | Grade |
|---|---|
| LATCH | A |
| Infant seat | A |
| Rear-facing convertible | A |
| Forward-facing convertible | B |
| Booster | B |
Where the anchors are
Lower anchors. Two sets, exposed for easy connection.
Top tether anchors. Three, midway down the seatbacks. Well labeled, but they sit under the seatback upholstery, so connecting one takes a bit of digging.
Installing an infant seat
Easy to install, and Cars.com's 5-foot-6-inch front passenger had enough legroom to be comfortable.
Installing a convertible
The rear-facing convertible was easy to install at the Level 2 recline angle, and the front passenger was comfortable in front of it.
A B: the top tether anchor is clearly marked but hidden in the seatback fabric. Cars.com installed it with the seat belt and removed the head restraint to seat it flush.
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.
Boosters and the buckle-yourself years
The booster fits once the head restraint is removed, but the buckles sit on short stalks flush with the seat cushion, so kids will likely have trouble buckling up on their own.

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.
