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.

Does this seat come with the base? Or is the base sold separately?
Best Answer: This doesn't have a separate base. It is one piece so there is no base to purchase separately.
Does this car seat have a handle so you can carry baby around in it?
Best Answer: This is a 3-in-1/convertible car seat so it's generally meant to stay in the car. Infant car seats (which are smaller and lighter) have a handle for carrying.

SlimFit3 is a Great Carseat
The SlimFit3 works great for our narrow 3rd row seat. It is well made and solved the issue of the difficulty of having 3 carseats in a row and buckling in for a narrower 3 row seat.

Perfect for 3 in a back seat
This review was collected as part of a promotion
I bought this seat for my son after having my twin girls and it's great - very easy to adjust and install. I recently swapped out two infant basket seats for these and now have 3 in my backseat. They fit perfectly! And all of the kids seem comfortable and happy. Definitely recommend if you're looking for something that can support 3 carseats in a back seat. I have a Hyundai Tucson for reference.

We bought this for our 19 month old for a trip driving trip. The set up was an easy, secure, and the baby looked comfortable. I would recommend this seat to anyone needing to matriculate into a toddler seat. 5 out of 5.

Finally a car seat that works for our family! With three little ones and no minivan, the Graco Slim X gave us the space and confidence we needed. Comfortable for the kids and a huge help for parents!

Buckle too low
The buckle is so low and does not have any slack to pull up higher. It is extremely uncomfortable for our 1 year old.
