This booster seat is super comfortable and provides great safety for my child. I love that the backrest is adjustable and offers good side support. It's also easy to install and clean. I have to highlight its material of good durability quality and incredible price I recommend it 100%

This car seat is brilliant, it's looks we really nice as well. Easily cleaned, a must with small children. The cup holders come in very handy too. It's easily adjusted and has great safety features. It's well made of durable materials so should last a long time. I would recommend this car seat to parents.

The ADVANCED Big Kid LX is an excellent choice for parents who want comfort and convenience for their child during long road trips. The seat is well-padded and provides great support, making it comfortable even on extended rides. I love that it includes child-controlled features, which give kids a sense of independence and keep them entertained. The installation was straightforward, and the overall build feels sturdy and safe. Definitely a product that combines comfort, safety, and ease of use. Highly recommend!

I bought 2 of these Big Kid Highback 2-in-1 Belt-Positioning Booster Car Seats for our almost 5 and 6 year olds who were outgrowing their other seats. These seats were very easy to put together, out of the box, and installing in the car was super quick (just place on desired seat that includes lap and shoulder belts and you're done!) I love that these come with removeable covers for cleaning and that the seats themselves dont take up hardly any room compared to our previous ones. The included cup holders are made to fit virtually any size and shape cup, which is a plus, but at the same time they are positioned a little closer to the seat area, so I dont like that a cup may potentially push into the side of your child's leg if she places her legs further out to the sides. I also wasn't a fan of the way they built the height adjustment. Instead of the head rest being raised, the entire backrest portion of the seat moves up from the seat bottom, and since my girls are taller, this made the seat feel flimsy. We did keep the seats, however, because the backrests will not be needed much longer and the booster seat bottom seems fine. Overall, ok seats, but definitely not my favorite.

Love how the chair looks. Looks sporty and my son loves it. My only concern is the seat belt. It goes on a separate strap to make sure the child is secure but if you don't take it off it's gets stuck which is a pain. It would be nice if the seat belt went back smoothly instead of take it out off the strap all the time.
