✅ Seat is good for you if:
✅ You have tall front seat passengers and/or a vehicle with limited back seat space.
The Graco TrioGrow SnugLock is one of the best convertible car seats for small cars. It is one of the most compact in front-to-back space!
Because the seat has numerous recline positions, it can get very upright which lessens the footprint of the seat from front to back. If you have a tall driver or passenger or are just really tight on that legroom in the second or third row of your vehicle this seat is one of your best bets.
✅ You travel internationally with your children.
A car seat must be locked in place for safe installation, and outside of the US and Canada, vehicle seatbelts typically don’t have the same locking mechanism as US and Canadian vehicles do. But the great thing about this seat is that it has a built-in seat belt lock-off! This means you don’t need to worry about using a locking clip when traveling internationally. This seat will easily install in any vehicle that has seat belts!
✅ You want to skip an infant seat.
We’ve found this seat fits newborns pretty well! If you are expecting a smaller-than-average baby or a preemie, we would still recommend an infant seat instead, as that will have a better fit.
✅ You have a vehicle with nonremovable headrests.
Vehicle headrests that tilt forward and/or are nonremovable can be tricky when a car seat is forward-facing. The Graco TrioGrow plays nice with headrests like these!
🚩 Use Caution If:
🚩 You need to fit 3 people in one row of the vehicle.
This seat is 19″ wide. Most vehicles cannot accommodate a car seat this size in a three across configuration.
️ Stand Out Features:
Easy installation with the SnugLock lock-off
This is an easy car seat to install. All you have to do is thread the vehicle seatbelt through the correct belt path, gently remove any obvious slack, and close the SnugLock lock-off. And that’s it!

⚠️ Quirks to be Aware Of:
⚠️The cupholders are required.
Once they’re clicked into place correctly, they can’t easily be removed! They must always be attached when the car seat is in use.
✈️ Airplane Use
The Graco TrioGrow SnugLock is an FAA approved car seat. While is is 18 pounds, it is still one of the lightest options available if you want a seat that has a seat belt lock-off. This is one of the best convertible car seats for international travel. For help with all things airplane travel and car seats, check out our Wheels Up Course and private Facebook group.

A note about crash-tests
How does the Graco TrioGrow SnugLock perform in crash tests?
Well, that’s a great question. We know it passes the strict federally required testing for all car seats sold in the United States. But we don’t know exactly how it performs. That data isn’t released by any official sources in the US — not by car seat manufacturers, not by government agencies like NHTSA, not anywhere!
There are a few third-party websites that claim to offer objective crash test data that compares car seats. But we at Safe in the Seat ignore that data for a few big reasons. First of all, third-party car seat crash tests don’t actually give us meaningful data! Car seat manufacturers crash-test their products hundreds, even upwards of a thousand times. They crash test the finished product in every single installation configuration using every applicable-sized crash test dummy, not to mention a whole lot of testing at each stage of the development process too. So one or two crash tests completed by another organization just can’t give the same level of information! One or two crash tests aren’t going to represent the overall average performance of any car seat across its lifespan.
