We love it! Super easy install!

[This review was collected as part of a promotion.] We moved to this when my kiddo moved to forward facing, as I didn't like the way our old seat installed forward. It was super easy to put together, and even easier to install! So easy, I uninstalled it and reinstalled it just to show my friend how easy it is! The harness moves super smooth, and adjusts nicely. My kiddo loves this seat. She's super excited that she has armrests like mommy. 100% recommend! Will be getting a second one when our next child moves to forward facing!

Nice looking, easy to install and use, lightweight

[This review was collected as part of a promotion.] This is a comfortable, sleek, safe high back booster seat for my growing kiddo - we already have 3 other carseats from Graco and this is the best looking one so far. We are moving her from the harness to the seatbelt and this made it so easy. When my younger one is forward facing, we will be happy to use this seat on him too!

Perfect for kids

[This review was collected as part of a promotion.] I bought this for my daughter who prefers stationary car seats over the swiveling ones. It was incredibly easy to install and is very solid and comfortable. It wasn't too expensive, either.
