Seat is Good for You If:

You have a vehicle with non-removable headrests. 

We’ve found that this seat tends to fit well in most vehicles, even ones that have non-removable headrests.

You have a small backseat.

This seat is fairly compact rear-facing, so it can be a good option for smaller vehicles or to go behind tall passengers.

You need to fit 3 across.

If your goal is to fit three car seats side by side in your vehicle, the Graco True3Fit LX becomes a top contender. Measuring just 16.7 inches in width, it ranks among the narrowest car seats available in the market today. This makes it an ideal choice for families facing the challenge of accommodating multiple car seats in their back seat. The forward-facing mode has a seat belt lock-off, which can be helpful to get a tight installation in some tight center seating positions. Whether you have triplets, three kids of varying ages, or simply need to make the most of your vehicle’s limited space, the True3Fit LX provides a practical and space-efficient solution.

Use Caution if:

You want to skip an infant seat.

While the Graco True3Fit LX offers a plethora of benefits, it’s essential to exercise caution if you intend to skip using an infant car seat. We recommend waiting until your child can sit unassisted before transitioning to this seat. The True3Fit LX, even in its most reclined position, may not provide the necessary support and comfort for a newborn due to its slightly more upright orientation.

You want this to be the last seat your child ever needs.

While the high-back booster mode has 57″/100-pound limits, there is no child that will fit at either of those limits. The harness mode will last about a year after the harness mode is outgrown, as the highest belt guide position is about an inch higher than the harness. You will need another booster once your child outgrows this seat.

Airplane Use

The Graco True3Fit LX is an FAA-approved car seat. Just get a travel cart to maneuver through the airport! Because it can be very compact in rear-facing mode, it will fit in that direction on most airplane seats. It is narrow as well, so you probably won’t even need to put the airplane armrests up to fit it!

If you are traveling internationally, you may be able to get away with installing with the lower anchors if the child is under 45 pounds and if the vehicles you end up in have lower anchors. But we would recommend contacting Graco for a free locking clip in case you need to do a rear-facing seat belt installation since most vehicles outside of the US and Canada will not have locking seat belts. For help on how to install a car seat with a locking clip, check out our video here. The forward-facing installation does have a seat belt lock-off. So no locking clip is needed when the seat is being used in that mode internationally.
