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.

Actually a slim car seat!
This review was collected as part of a promotion
This is actually several inches slimmer than the other “slimfit” graco car seat and has made it so much easier for us to fit three car seats across in our 4Runner! We currently have the other slim car seat (that isn’t very slim at all lol), an infant seat and this seat and they fit snug but comfortably. We will definitely be buying this one again when our baby outgrows the infant seat! It was very easy to install.

Great compact seat for 3 across
This review was collected as part of a promotion
Bought these so we could be 3 across in the back of my sedan. They’re a great size and I actually like that they hug my kids a little closer, and cup holders are closer too than in our old seats. Installation and safety are always my top reasons for choosing Graco. It’s very straightforward and simple and trustworthy!

Comfy and safe!
This review was collected as part of a promotion
The fabric and seat seems very soft, padded and comfy for my little one. It was not too difficult to install and I love that it has cup holders too. Definitely a little more leg room on my extend to fit but not cramped at 1.5 years.

Best car seat for multiples
This review was collected as part of a promotion
I have 4 kids (11,4,3, and 1) when our 3rd baby was born we struggled finding a carseats that would fit in the back of our sentra. We could fit 2 but then our bigger kid was squished. Then we found these. We started with just one then ended up buying our 3rd last year when our youngest was born. They all 3 fit in the car and are easy to install. They are also easy to take apart to clean and button back together like a charm. Anytime we need to adjust straps we can do it with them in the seat in like 5 seconds. We will never buy a different carseat these are the best!
