This car seat has been great for my six-year-old grandson. He easily straps himself in. It’s easy to take from one car to the next and I love that it gives good side support for his head. I feel very confident that this was a great purchase and would keep him safer in the unfortunate occurrence of an accident.

We finally moved on from a toddler car seat. Our biggest criteria during our research was safety. This Cybex was easy to install. You basically stick the latches into the car's installed latch system and that's it. I thought we might miss the cupholders. But we use the inbuilt car cup holders. My son is happier using those than have carseat cup holders digging into his thighs. He can climb into the car much more easily now. He still falls asleep in the car, so I assume it's comfortable. If I think he is going to have a nap. I tilt the headrest back slightly before I get going. We bought another one for our other car and as we use that one for long journeys, we bought a separate foot rest and he can sleep for hours in that seat.

Our son is almost 9 and has mild hypotonia also a vp shunt so we needed something that would keep his head and neck truly safe . This came up as the most recommended. He loves it and it holds his head great even tilting it back. Loved that we can take it on our out of the country trips since it folds and all.

This item actually arrived sooner than expected! It is super light weight! The folding seat works super nicely and was easy to fold and unfold, the installation was super easy! I think this has been the easier car seat we have installed. The clips to install just click right in, it has a green indicator so you know it’s installed correctly and a red one if there’s an issue. It’s super thin, we were needing a thinner one for our car since our seats weren’t as wide. My daughter says it’s super comfortable! The downside is the cup holders are sold separately- be aware of this because there won’t be any if you don’t purchase them. Other than that it’s a super nice high back booster and our daughter loves it.

I have a 7 yr old but he still fall asleep often in the car. I purchased like five different boosters seats, but I was always terrified of his head falling down when we slept. Finally with this one, the problem stop! He sleeps comfortably and his neck is safe! Price point is definitely higher than my beginning budget for a booster, but totally worth it in my opinion, plus it doesn't look bulky and he can buckle his belt himself. Very happy with my purchase

It’s lightweight, super easy to install and change the recline, it also is not as wide as I was expecting so that’s nice. Love that I can easily take it in and out when I need my car chair back.

Fantastic seat. Very light and easy to install. Our kid loves it. The only wish is that it were available in pink.

This booster seat is safe and incredibly easy to install. I need to take it in and out of my car frequently, so ease of installation and removal was of utmost importance, along with being sure the seats kept my grandchildren safe and secure. It's also very lightweight, so easy to move around.
