Its Simply Safe Adjust™ harness allows you to adjust the harness and headrest together as your child grows, with no time-consuming rethreading. You'll appreciate the strength of the steel-reinforced frame, 4-position recline for comfort and fit, and an updated, sleeker design. The booster car seat also includes 2 personal cup holders to help your little passenger enjoy the ride.

Kiddo Loves It
My oldest finds this carseat easy to climb in/out of. Highly recommend for anyone who has kids that are 4+yo.

Overall experience
Installation was very easy. Besides following the instruction manual, there are also helpful installation videos available on YouTube.
Overall, the car seat looks safe and comfortable. The fabric feels soft, although my niece tends to sweat easily, so it can get a little warm during the summer. However, with the air conditioning on, it hasn't been a major issue.
Since this car seat doesn't have extremely deep side bolsters, I think it may be a better fit for slightly older children who prefer a roomier seat.
A couple of things I wish could be improved: the side headrest padding feels a bit firm and doesn't have as much cushioning as I expected. Also, there are only two crotch buckle positions. Having one additional position would provide more flexibility. My 5-year-old niece is already using the outermost slot, and when she wears a fluffy dress, the buckle area can feel quite snug. She has occasionally mentioned that it feels a little tight and uncomfortable.
That said, for this price point, I really appreciate that this is a 3-in-1 car seat with a steel-reinforced frame. The overall safety design gives me peace of mind, and I feel confident keep using it.

Awesome Seat!
I bought the seat when my 3-year-old was ready to be forward facing. The seat she had was very difficult to strap her in and I didn't want to spend the rest of her time in a car seat fighting with buckles. This car seat was so easy to install, it doesn't take up too much space, she's super comfortable in it, and best of all she's easy to strap in. I loved this seat so much that I bought another one for the other car. Highly recommend!

Perfect Upgrade!
The perfect upgrade from our 4ever. I love that it’s less bulky but still has a 5 point harness.

Love the color
We chose this car seat because it has the option to recline, however, the recline feature is quite difficult to use depending on your backseat. Otherwise, we live the color and the adaptability for it to also become a booster as our kiddo gets older.

Perfect for kids
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.

We love it! Super easy install!
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!
