Easy to Install and Versatile as Kids Grow
[This review was collected as part of a promotion.] 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.
[This review was collected as part of a promotion.] 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).

Saved My Child's Life
This carseat saved my daughter's life! We were hit headon in a terrible car accident, but my 3 year old was completely unharmed thanks to this seat. I will be buying this one again!

Best Jeep Owners Car Seat
[This review was collected as part of a promotion.] 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 review was collected as part of a promotion.] 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 we travel in the airport.

We’re not recommend it does not stay still even if you try to fix it. I have read the manual and no matter what we do different cars it wobbles too much.

Defective
I purchased this car seat from Target in Carlisle, PA, it was missing the cupholders. They did an even exchange for the same model, the next one had the same issue. It was missing the cupholders. It is defective coming from the manufacturer. I asked them to remove it from the shelves due to this issue.

Hi. We are sorry to hear about your experience. The Tranzitions has the cup holder inside of the cupholder slot. If you refer to the manual, in the cup holder section it advises where and how to assemble those cupholder. -The Graco Team

Terrible service went to pick up 4 hours never heard anything couldn't find my order because it was stuck in a glitch and I had to repurchase the item while its in limbo. So basically had to buy it twice and wait for original order to go through and cancel it could be days

Sturdy! Secures like a car seat with the independence of a booster. My child loves this booster for it’s comfort, and ease of use. We have this booster in multiple cars.

Car seat
This car set is just what we needed. I love how it can be used all the way until our child doesn’t need a car seat any long.

Besr bang for buck for forward-facing!
Best bang for your buck in our opinion. A few things to not love, but overall for the price it is the best! Cup holders are wimpy and pop loose occasionally. The seat is light, very easy to adjust and seems comfortable for our kids. Very easy to transition to each seat option as well. The straps to tighten the seat down can be a little tough, but once it is in, it is snug!

Forward-facing car seat
[This review was collected as part of a promotion.] 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.

I love this brand chair. I have my three year old who also has one. Easy to assemble. And definitely comfy when we go on trips.
