Description

This Graco car seat is their slimmest design. It fits three car seats across in your back seat (in every configuration), saving space without compromising safety.

The narrow all-in-one design grows with little ones from rear-facing harness (5-40 lbs) to forward-facing harness (26.5-65 lbs) to highback booster (40-100 lbs).

Integrated belt lock-off makes for easy vehicle seat belt installation in forward-facing mode, and allows you to position seats to maximize space with three across.

Graco’s exclusive push-button InRight LATCH provides an easy, one-second attachment with an audible click to help ensure secure installation.

The No-Rethread Simply Safe Adjust Harness System allows you to adjust the height of the headrest and harness to ten positions with just one motion for just the right fit. Adjust the four-position recline for a better installation and a comfortable ride.

The Rapid Remove cover comes off in 60 seconds, without uninstalling the seat or removing the harness, and it’s machine washable.

Breathable mesh AirFlow channels provide improved ventilation to keep kiddos cool and comfortable. Two cup holders are designed to work with the three-across configuration to keep drinks and snacks close at hand.

Fuss-free harness storage pockets conveniently hold the harness out of the way while children get in and out. Removable, plush head and body inserts also keep baby feeling cradled and comfortable.

The steel-reinforced frame provides strength and durability for years of use, and EPS energy-absorbing foam provides effective impact energy management.

For peace of mind, it’s Graco ProtectPlus Engineered. This is a combination of the most rigorous crash tests that helps to protect passengers in frontal, side, rear and rollover crashes.

Great car seat!
This review was collected as part of a promotion
I also have a Graco Extend2Fit. And I honestly wish I just had 2 of these. While I have not tried to clean it yet. I love how much more airflow this car seat has. It also has some nice design features that really make it feel quality.

Perfect Fit for Twins
This review was collected as part of a promotion
I purchased 2 of the Slimfit LX Car Seat. They are very comfy for my twin granddaughters. The perfect design of the seats allows me to have them installed in my car beside their older brother with no problems. I feel good knowing that my grandkids are safe with Graco carseats and I can fit all 3 in my car safely and easily. I would highly recommend this carseat.

Love it so much, this was our 2nd!
This review was collected as part of a promotion
We had researched many options when our first was transitioning out of his baby car seat and found this. We’ve loved it so much that when the time came for us to get one for our 2nd born, we got another! This car seat has endured trips across the ocean three times over and protected our kids on multiple continents. Needless to say, we’re fans.

Highly recommend

This is our 4th graco car seat and first time getting a slimfit. Same great quality, super easy to unbox and install. Highly recommend for a smaller car or 3 across.

Narrow for 3 Across
This review was collected as part of a promotion
I bought this as we are planning to have our third and need the ability to fit 3 across. The Diono version seems to be out of stock permanently and this carseat is supposed to be more narrow anyways. Will update as time goes on to see how it continues to hold up. This is the most narrow carseat on the market (after upgrading from the infant carseat, because the infant carseat is technically more narrow).

Awesome car seat!
This review was collected as part of a promotion
Excellent car seat! Have used Chicco for years, which I still love, but this car seat exceeded my expectations! Especially if you need a slim car seat for a tight 3 across, this is a fabulous option.

Works great!

It sits more upright than the infant seat we were replacing, so watch the angle if your little one naps in the car to help keep them comfy.
