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!

Love this seat
[This review was collected as part of a promotion.] We love this seat! It is such a cute color and it was easy to install. We love that the cup holders don’t come completely off so we can’t lose them. Straps are comfortable and safe. My only complaint is that the purple color shows every single stain and is impossible to keep clean.

Fantastic product
[This review was collected as part of a promotion.] We bought this car seat originally for our first born and came back to it for our second child. Both fit great in the backseat. They are comfortable and safe for the babies. Easy to install and adjust as needed for best sitting posture/ ergonomics. Highly recommend it for new parents, small or big vehicles.

Perfect Car seat for Grandma
I am a grandma and purchased this car seat to be able to transport my grandchild as needed. It is extremely easy to install and remove from my vehicle. My grandchild seems to be very comfortable in the seat and I have no safety concerns.

If you’re like me and doing so much research and measuring and being scared if they’ll actually fit in your car. I will let you know that 3 across fit perfectly in a 2018 Honda Civic and also a 2022 Toyota RAV4. Currently have two forward facing and one rear, but any configuration would work! Also took my husband hardly any time to get 6 installed

reliable and practical
It is a great combination of comfort, safety and convenience. It gas a slim design that saves space in the car without sacrificing comfort for the child. The seat feels sturdy and well-made, the padding is soft, and the adjustable headrest makes it easy to grow with your child.

Easy and basic!
[This review was collected as part of a promotion.] Recently purchased and I am pretty happy with it. One complaint I have is the size of the cup holders, they are too small for some of the water bottles I have. This is the first seat I have had this issue with. Other than that, I would say it is a decent seat overall.

Great Car Seat!
[This review was collected as part of a promotion.] This car seat sat perfectly in my car. Easy to install and the best part is that its stable when it comes to driving. Graco is great! I definitely would shop again when I need a new car seat!

Toddler’s head tilted & chin was touching chest!!
[This review was collected as part of a promotion.] First of all. I LOVED how slim & compact it is & that it is easy to install. Loved the removable cupholders also. HOWEVER, my toddler's head tilted forward when she fell asleep & her neck literally bent down (chin touching chest). I tried adjusting her head and it was so unsafe. I had it for not even a week & returned it to purchase and E2Fit 3-in-1 (which we had one & is a favorite in our book).

Great size for small SUV
[This review was collected as part of a promotion.] This is our second SlimFit 3-in-1 car seat and we love it. We have a small SUV and there is still space in the middle seat, after installing both car seats on each side in the back.
