The best carseats I purchased!

I don’t know why I waited for so long to purchase this carseat for my twins. Maybe because some reviews I read, it cannot be tightened and knowing I have 2006 Toyota tacoma truck. Guess what? it was an easy installation and way better than I had. My twins loved it already. It’s very lightweight and properly secured in the car. It checks the box ✅lightweight ✅ slimmer ✅affordable ✅easy to install ✅easy to wash/clean ✅perfect size for my twins ✅ love the color especially the purple/black for my twins girl.

Don’t waste your money

I got my daughter the purple one about a year ago and I love it so I bought my son the same one in black. They’re very easy to install and easy to take apart to clean. I love that it’s the last car seat/booster I should need to buy. They’re also very lightweight and easy to move around. My kids find it comfortable and often fall asleep in it.

Good next step for an older toddler

[This review was collected as part of a promotion.] Switched from an all in one to this for my older child. It provided more leg room and gave me a better view out the rear window. It provides the same Graco safety I had in my all in ones in a lighter package. The install was the same as my other Graco seats and it should be the last seat I but for my child as it can adapt as he grows.
