Easy to use
Easy to use, perfect size for our very big 3.5 year old. Only issue on installing was my cars headrest getting in the way. My son can buckle himself easily.

Horrible install not safe!!
Not only is this seat nearly impossible to get a secure install, it does not even FEEL safe. We’re a busy family and moving this seat from car to car makes my anxiety worse!! I’m not sure how this seat passes any safety standards.

My Son’s #1 Car seat by far
Absolutely Love this seat!! My son is 5 and is sooo comfortable in this seat, his head never flops around when he’s asleep and he never wakes up complaining about neck or back pain like he has with others. It secures extremely well in our cars, we love it so much we bought 3! One for mom, dad and grandma!

Safe, Comfortable, and Grows with Your Child
The Tranzitions™ 3-in-1 Harness Booster has been a great car seat for our family. It’s sturdy, easy to install, and my child finds it very comfortable even on longer rides. I love that it grows with them from a harness seat to a booster, making it a practical and long-lasting option for parents.

Great car seat for my 2.5 yr old
My son loves this seat, even more than his Graco Extend 2 Fit. He can crawl in and out himself and it’s the usual easy, light, simple fit for our car and needs.

Great booster but confusing to install
Nice quality booster, but the way the booster was packaged it made it very hard to understand how to install it. Wish it had full cup holders. My child finds it comfortable.

Easy to Install and Versatile as Kids Grow
This seat is easy to install and allows for a lot more passenger room. It is a great transition from a forward facing seat to a booster.

Perfect for a 4 year old now, and to grow into.
We were looking for a transitional seat for our 4 year old granddaughter, because her brother had outgrown his infant seat/stroller and needed to move up to hers. She's on the lighter side, and this model is great. Its easy to install and use, comfortable for her, and looks good too (we purchased black).

Best Jeep Owners Car Seat
I absolutely love the car seat! It’s not bulky and the color is very demure! My toddler loves it and falls asleep comfortably. The straps adjust easily, it was very easy to set it up in the car. I look forward to adjusting it to the booster level for when she gets older. I recommend this car seat for all Jeep owners.

Saved my sons life
This car seat is basic yet safe! We were in a car accident where we rolled twice. My son had not a scratch or bruise. We love how simple it is to use and how slim it is. The cup holders come off easily and it does slide a little even after we strap it in (which is why I gave it four stars). But overall it’s great and it saved my son. Also love how light it is esp when w...

Forward-facing car seat
This car seat has been great for our 3.5 yr old who we transitioned to forward-facing. It is very easy to install and uninstall, and lightweight to move from vehicle to vehicle with ease. Having multiple color options was an added bonus.
