Stand Out Features of this Car Seat

It’s very compact rear-facing.

It doesn’t take up a lot of space in the rear-facing mode. We’ve found that it fits well in a lot of smaller vehicles and behind taller parents.

Forward-facing lock-off

In the forward-facing mode, the Graco SlimFit3 LX offers a seat belt lock-off feature. In fact, this feature simplifies the installation process, ensuring a secure and tight fit in various car models. It’s especially handy when dealing with center seating positions or tight spaces, providing added peace of mind for parents concerned about installation safety.

Removable cupholders

A unique feature that sets the Graco SlimFit3 LX apart from other Graco seats is its removable cupholders. These cupholders add a layer of convenience to your child’s travel experience, providing a place to store drinks and snacks. Additionally, when you need to fit three car seats in a single row of your vehicle, removing the cupholders can be a practical necessity, allowing for a snug and secure fit of multiple car seats.

Seat is good for you if 

hearts-suit

You need to fit 3 across.

If your goal is to fit three car seats side by side in your vehicle, the Graco SlimFit3 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 SlimFit3 LX provides a practical and space-efficient solution.

Your back seat space is very limited.

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

Your vehicle has non-removable headrests.

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

Use caution if

c-warning

You want to skip an infant seat.

While the Graco SlimFit3 LX offers a plethora of benefits, it’s important 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 SlimFit3 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.

c-warning

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.

Quirks to be aware of

c-question

Similarly named seats

In the world of car seats, it’s important to be aware of similar-sounding models. Apart from the Graco SlimFit3 LX, which is a narrow option, Graco also offers the Graco Slimfit 3 and Graco Slimfit 3 LX, neither of which boasts the same narrow design. These alternatives measure about 19 inches in width, making them wider choices. It’s also crucial to double-check the specific model you’re considering to ensure it aligns with your space requirements. Additionally, keep in mind that Graco True3Fit, a Walmart exclusive, is essentially the same as the slim Graco SlimFit3 LX, offering a narrow profile suitable for fitting multiple car seats in your vehicle comfortably.

Airplane Use

The Graco SlimFit3 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.

SITS Bottom Line

In conclusion, the Graco SlimFit3 LX stands as an exceptional choice for families seeking a narrow and space-efficient car seat solution. Its ability to accommodate three car seats across and its compatibility with vehicles featuring non-removable headrests make it a versatile and practical option. Additionally, the forward-facing lock-off mechanism and removable cupholders enhance the user experience, ensuring a secure installation and added convenience.
