Customer Review: Love love love this. Putting it together took all of 30 seconds. Set up in the car was also a breeze, I especially love the added safety of the tension belt clip ins to the seat of the vehicle like a “regular” car seat to keep it extra sturdy. I wish it felt as “sturdy” built as Graco especially for the price.
Customer Review: Love the car seat but had to place it on a window side because of the tether hook locations. I removed the car headrest and the booster cinched snugly against the seat with the latch tightening strap. My grandchild didn’t like not being able to see me when we talked (age 4.5 yrs) so I easily moved it to the other side.

We’ve only used it with buckles, but it comes with clear diagrams for both. The buckle can be slightly annoying to get through at first.
Customer Review: Wow, this carseat is great! We had to get a new carset for our 3 year old and she loves this one. We also love that it grows with her and we do not have to keep buying something new when she grows. Easy to install and it sits perfectly in our Equinox. Only pain was actually being able to adjust the straps.

Frequently Asked Questions
Q: What is the best age to switch to an adjustable car seat?

Q: How do I know if an adjustable car seat is safe?
