Description

The Graco SlimFit3 LX 3-in-1 Car Seat is our slimmest design that fits 3 car seats across, saving space in your back seat without compromising on the safety you trust and the features you need. This narrow all-in-one car seat grows with your child from rear-facing harness (5-40 lb) to forward-facing harness (26.5-65 lb) to highback booster (40-100 lb). We tested our lightweight 3-across car seat in every configuration, to help ensure your growing family can fit in your vehicle, even with children of different ages who ride in different modes, or when paired with select other Graco car seats. Integrated belt lock-off makes for easy vehicle seat belt installation in forward-facing mode, and allows you to position your seats to maximize space with 3 across. Graco’s exclusive push-button InRight LATCH provides an easy, one-second attachment with an audible click to help ensure secure installation. We made thoughtful design choices to make the SlimFit3 easy to adjust with 3 car seats in the back seat. The No-Rethread Simply Safe Adjust Harness System allows you to adjust the height of the headrest and harness to 10 positions with just one motion for just the right fit. Easily adjust the 4-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 is machine washable. Plus, the SlimFit3 is slim enough to fit 3 across, but spacious enough to keep your growing child comfy. Breathable mesh AirFlow channels provide improved ventilation to keep your child 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 your child gets in and out. Removable, plush head and body inserts help to keep your infant 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. This car seat is Graco® ProtectPlus Engineered™ to the newest testing standards for side impact and beyond—because the safety of your child shouldn’t stop at the standard

Kid loves this carseat! Its very lightweight fits well in smaller vehicles with minimal space. I love the back tether latch its so easy to tighten and release! Its very comfortable anytime I take it inside to use in another vehicle my kid is all over it. We love the color on it, it’s just so pretty. This carseat is an absolute hit, I only wish I got it for my kid sooner and the quality is good just as expected it feels so nice im almost jealous! The airflow is a very nice feature for some ventilation and just for comfort. ... show more

Bought this car seat for my nephew. He’s spends a lot of time with me & I got tired of moving my sis car seat back and forth. It’s so perfect because it’s slim and my car is pretty small. I have a Toyota Camry 2008 so it fits perfectly without making everyone feel squished. The color looks so good in my car. Reclines forward & backwards perfectly. Super padded & comfy. Quite easy to clean. Very sturdy too it doesn’t move an inch. I love it & would purchase again. ... show more

    • Slim, Safe, and comfortable
Size: SlimFit3 LX Color: Kunningham 2.0
We now have 3 of these car seats. They are slim and fit the car great. they are easy to install and easy to adjust. I absolutely love how sturdy they are. I really feel safe and comfortable putting our kids in them to drive. They never complain about being uncomfortable and they are the only car seat that car fit 3 across in our SUV. 100% recommend. ... show more

I got two of these to replace an infant carrier in our cars but also to see if you could fit two of these and an infant carrier across in a car and small suv. I have one forward facing and one rear facing and one rear facing infant carrier seat (the removable kind, a safety 1st onboard I think). We have an Elantra and a Mazda CX-50 and they have the same backseat space. I put the forward facing in the middle and both rear facing on the sides. They definitely fit with no room to spare but I’m super impressed with the graco slim fits because the infant carrier seat takes up so much of that space. The middle slim fit has to move off enter to make room for the infant so they each get less than a whole seat of space really. Using three of these across with two being rear and one forward would be an absolute breeze in our cars. Car seat wise though I also really like these. The removable cup holders are really nice and since everything is so compact, it actually makes it feel easier in my opinion. As with most of the graco seats, installation was super easy with either latch or seatbelt. The cover seems to be easy to remove as well for quick cleaning. The only downside I have is that there is obviously way less leg space than the extend2fits, but I think that’s a fair trade off for fitting three car seats in a car. ... show more

    • Actually very slim
Review Image by mat mat
Review Image by mat mat
We got this as an upgrade for our first child. We specifically got the slimfit3 lx due to its small size of 16inches wide and it's ability to fit 3 across in a car. Unlike the other slimfit models this one is the slimmest and will actually fit three across, you have to pay attention to the model you're looking at buying and the width. For the slimfit3 lx, the installation was easy using the latch system, the instructions were very clear. I like that there are two options for the recline and we're able to sit the baby up more if needed. She is way more comfortable in this than her infant car seat and I'm glad we upgraded. This carseat has more airflow than her other seat too and it helps keep her cooler when its hot out. I love that this seat will last us through the years as she ages. I like that in the future it can be converted to front facing harness and then into a booster, making it good for all ages. The headrest adjusts to fit the baby better as they grow and allows you time before hitting the 40lb weight limit for rear facing. The seat itself is very sturdy, not too heavy, only 19lbs, and its easy to transfer cars if needed. I feel confident in this seat and am glad after researching that we went with this one. This is an investment but im beyond happy we got it because it can be used for such a long time as our baby grows! Highly recommend to every parent needing a slim profile, comfortable and sturdy car seat for their baby or kid. ... show more

    • I love this seat
Size: SlimFit3 LX Color: Katrina 2.0
I had the graco infant seat and knew I wanted to stay with them for the next once. 1. I absolutely love the color. My interior is completely black and it looks great in there. 2. Very easy to adjust the height and making sure the base is stable. Very easy to tighten the straps and everything as well! 3. Very durable as my daughter was playing on it when I took it out of the box, tipped it over and they were both fine lol 4. Leave so much room in my back seat still! My brother also tried it while he was driving and had plenty of room to move his seat back when it was in his car! ... show more

Great car seat that adjusts with size and age of child. Easy to install and transfer between cars. Very well made and comfortable. Appropriate and safe levels of padding that dont affect safety of straps.
