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.

Really does fit 3x

Installation is so easy on this! Also it really does fit 3 across even in a compact sedan (Nissan Sentra).

Quality Car Seat

It's a great budget quality car seat. The adjustments for the bottom strap is more difficult than our other Graco seat but our son is comfortable in both seats.

Good car seat, slim function is ideal
This review was collected as part of a promotion
Purchased this car seat to move our 18 month up while we used her original car seat for new babies.
Hoping to graduate the twins to the same in a year and half or so and fit the three across a bench seat in vehicle.
Car seat is a little harder to install than the ones with the separate base. I feel that even though the recline is set correctly, our daughter’s head does tilt forward a little. I would be hesitant to use with young babies.

Exactly as advertised
This review was collected as part of a promotion
I was looking for a car seat that fits into a small car, and can be easily carried around. We have two cars, and I am often moving the seat from one car to the other. SlimFit is easy to install with the latches, and light enough that it is not too hard to carry.

Great car seat for compact fit
This review was collected as part of a promotion
This car seat is constructed with high quality materials and was very easy to install. It is also very compact making it the perfect second car seat for our compact sedan. We previously had the Graco Turn2Me and have been very satisfied with both the quality of Graco car seats, the lifespan of the seats compared to other brands, and the amazing Graco customer service. We are already looking forward to buying a second SlimFit for our other car.

Pros and Cons
This review was collected as part of a promotion
I was so impressed with this seat right out of the box. However it’s not the easiest to tighten and it seems like the head protection is too high but it’s where it has to be for the straps to come right above the shoulder in forward facing. I do love how narrow it is though. Not my favorite but it will do.
