Perfect car seat upgrade
Great seat and comfortable for my daughter she loves it so much and makes her feel safe she instantly falls sleep in this car seat when it’s time to go on the road. I would definitely recommend it’s very sturdy and built well, when unboxing the set up was quick and easy because it came in two pieces the first one which was the bottom base and the second the top back support, all we did was click it together and it was ready to install into my car.

A well- priced safe combo child seat
A great seat for grandparents or a second vehicle. This seat is great -its easy to put in the car has an easy to use harness and is very lightweight. Both pieces can be packed away into a bag so easily when you don’t need it in the car. The cup holders are a great plus too. Priced well and is getting a lot of use on short and long trips

Color is so cute & my big 2yr old fits in it perfectly.
Love it! I have a two year old who is pretty big. Shes 40lbs last I checked and was out growing her other forward facing car seat. This one is definitely more comfortable and perfect for her! I love that it can be turned in to a booster seat for when she gets older. 🙂 and I’m obsessed with the color. I was trying to choose between this one and another one that was more pricey but I’m glad I chose this one!

Perfect for multiple kids + small back seats!
This is the second time I’ve purchased this exact Graco car seat, and honestly it’s because the first one won me over. It’s slim, super convenient, and fits perfectly in my back seat. I need to have two car seats in the back row and still fit three kids back there, and these Graco seats make it possible.With two of them installed, there’s still enough room for another child to sit comfortably in the middle, no fighting, no squeezing. The 6-point harness is a huge bonus. My kids get that “big car seat” feeling they love, but with the safety and security that gives me peace of mind.If you’re juggling multiple kids or tight spaces, this car seat is honestly a lifesaver. Highly recommend!

Great transitional seat for ages 3-8
Best of the forward facing seats. I’ve used on 2 kids both I waited until they were 3.5 years old to be in a forward facing as this is the safest way to follow. This seat is sturdier and most of these are not easy to remove but the clips on these are ok. Padding is good not great but compared to others it’s better and the size is enough for my “big for their size” 6 year old.

Llego en tiempo adecuado para niños de más de 2 años. –
Llego en excelente condiciones. Util para no cambkar de sillas conforme crece tu pequeño o pequeña. Tomar en cuenta que tiene menos soporte lateral a nivel de los brazos y piernas, pero nada grave.
