Excellent compact car seat
[This review was collected as part of a promotion.] This car seat functions perfectly for us. It fits well in the small back seat of our FJ Cruiser. We have installed the infant car seat beside it proving it would work well for 3 across. It fits well in the center with plenty for room for my 6’4” husband to drive.

Safe and comfortable
The best investment for my baby's safety! This Graco chair gives me a lot of peace of mind because of its reinforced structure and how robust it feels. The harness system is very easy to adjust and level indicators help you make sure it was perfectly installed. It feels of a higher quality and my son is very protected. Totally recommended!

Great, affordable car seat
[This review was collected as part of a promotion.] I purchased this car seat as a second seat for trips home to visit family. Assembly was straightforward, the chair is compact, and the seat has excellent safety reviews and ratings. It was very affordable, and I highly recommend it to others.

Three across!
[This review was collected as part of a promotion.] I am super happy with how slim and still comfortable these car seat are! I drive a crossover and am able to fit 3 car seats across! Huge money saver not having to upgrade my car! Graco is such a reliable brand and our family trust them!

Great product!
[This review was collected as part of a promotion.] We have loved our SlimFit3 LX 3-in-1 Car Seat for our little one. We purchased this a little over a month ago to transition out of the infant carry car seat and for our little one to use as she grows. The quality of this product has been great! We love the base latch on this model for ease of removing and switching to a different vehicle. With our older child we had the basic latches and the quick release of these is a game changer!

Love this car seat
[This review was collected as part of a promotion.] I originally purchased this carseat in 2024 when my daughter went from an infant carseat to a convertible carseat. Recently we were in an accident where the rear of the car took the biggest hit. Long story short, her seat needed to be replaced, so naturally we re-purchased this model since it had kept her safe and basically injury free from the impact. We loved the slim profile and the mesh vents before, but we have a whole new appreciation for the durability and safety of this seat.

Great car seat!
[This review was collected as part of a promotion.] We love this car seat and how much room it gives us in our car. My only complaint is installing it rear facing for infants. I find it a bit challenging. I'd recommend this more for children over the age of 2.

Fits a Honda Pilot middle seat in the second row!
[This review was collected as part of a promotion.] This seat is almost 3” narrower than my Safety 1st seat that it replaced. I was trying to find something narrow enough to fit in the center seat of my 2016 Honda Pilot and that was easy to pull the harness strap tight and this seat is perfect. I have an evenflo dual ride shyft, this graco seat, and a graco backless booster all in my second row and everyone fits just right. My favorite part though is how easy it is to tighten the straps. The seat it replaced never felt tight enough despite strong arming it every time. I’ll be getting another once my infant is out of the infant seat.

Great Slim Car Seat.
[This review was collected as part of a promotion.] The slimmest model you can find in the market. Yes, this will fit 3 across, which wasn't the main reason we bought this as we only have 1 child. We bought this because we have a small car and didn't want the back seat to be taken over by 1 car seat. It is also very light, easily removeable and to install with the click in latch system. The meshed materials also keeps the child cool and happy in long car ride. We have taken this car seat in 3 international trips (Croatia, Mexico, Italy) and our child who is now 3 has no complaint. It is easily removable to wash. We also have another model (the TriRide, which is about half or 2/3 the price of SlimFit3LX) in another car, and I would say it is worth spending the money on the SlimFit3LX. The materials, latch systems, size, weight, construct is much much better.

Great car seat
[This review was collected as part of a promotion.] This is my 4th Slimfit3 and 8th Graco car seat. Easy to adjust and install. I've bought nothing but Graco since one of their seats saved my family in a rollover car accident by stopping the roof from fully collapsing several years ago.

Finally a way to have 3 kids fit in back seat!
[This review was collected as part of a promotion.] Finally all 3 kids can fit comfortably in the back seat of my small SUV! No complaints from the kids after a couple of 14 hrs trips (well, plenty of complaints, but none that related to the seats or to their comfort!)

Perfect for growing family!
[This review was collected as part of a promotion.] I wish I just bought these to begin with. I bought different carseats, but the SlimFit3 LX 3in1 makes the most sense if you plan on having three across in most cars! The quality makes me feel like my babies are extra safe and relieved my anxiety! If you are thinking about best choices with a growing family this is it!

Fit three in a compact car!
[This review was collected as part of a promotion.] This is my second one and it has been working great for us! Easy to put on and off to wash and gives us the option to put three car seats in a compact car. We once had to give our friend’s four year old a ride and we fit two of the slims and one reg size Graco car seat no problem!

Easy to use/set up
[This review was collected as part of a promotion.] Easy to use and doesn’t take up much space. We had the infant carrier until this and this is notably less bulky. I have a midsize suv (rav4) and fits fine. Being able to move the harness straps up and down with the button is nice too and makes it easier to adjust as needed
