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

    • Great car seat for everyday use!
Size: SlimFit Color: Sydney
I bought this car seat for my daughter and was impressed with how well it fits in the car without taking up too much space. The slim design makes it easier to have other seats next to it. It feels secure and the height adjustment works well as kid grow. The padding is c comfortable, and the color looks nice and clean. ... 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.

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

    • Perfect Car Seat That Grows With Your Child!
Size: SlimFit Color: Jarret
I absolutely love this Graco 3-in-1 Convertible Car Seat! After a lot of research and comparison, this one stood out for its safety features, comfort, and long-term value — and it’s lived up to every expectation. The seat was very easy to install using the LATCH system, and it feels incredibly sturdy once it’s in place. I really appreciate that it converts from rear-facing to forward-facing and then to a high-back booster — it truly grows with my child, saving us from having to buy multiple seats over the years. My toddler seems very comfortable in it, even on long drives. The padding is thick and supportive, and the adjustable headrest and recline positions make it easy to get the perfect fit. The cup holders are a nice touch too — they’re great for snacks and sippy cups. Another thing I love is how easy it is to clean. The seat cover comes off without too much hassle, and I can toss it right in the washing machine. Overall, this is a fantastic investment for parents who want safety, comfort, and durability in one seat. Graco really thought of everything with this model — I feel confident every time we’re on the road. Highly recommend! ... show more

It’s a nice seat and fits well in the back of my 2024 Chevy Trax (chevys smallest suv) with the passenger seat slightly foward. It would not fit behind my driver seat and I’m only 5’8” I don’t like the “slim fit” name as you would think it would be smaller than other models. As you can see from the picture it’s actually bigger than the Graco Extend2fit ... show more

    • Much slimmer than expected
Size: SlimFit3 LX Color: Kunningham 2.0
Review Image by Kara Kara
Review Image by Kara Kara
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
