Sturdy and convenient

You can use for 3 different phases. Just got for my daughter that is one. Can raise head rest as she gets older. Once is beyond toddler years, can remove back and just turn in to big kid booster. And has cup holder. Easy to install and able to remove cloth to wash. Has one for my first child (now 8) and had to get same for my second. Love it

Great transition car seat!
March 6, 2023
Amazing seat! My son loves this! We switched from a regular car seat for my 5 year old to this one and he loves it. It's large and very roomy and he loves the pockets on the side for his toys and the cup holder!

Good product comparing to other brands

Easy to assemble. Good product. "Fuss-Free harness storage" is not really helpful since it's not deep enough, I wish it was a magnet instead of a shallow hole.

Snack compartment bonus
June 21, 2022
The "snack" compartment is great! You don't see that option in many car seats but it really comes in handy for snacks or small toys.

For a toddler that is tall, it's perfect as far as child restraint and it even has a cup holder.

Good option for growing toddler
May 10, 2022
We had a Graco extend2fit and graduated our 2.5 year old into this, so that our 9 month old could have the extend2fit. Not disappointed, as we had a great experience previously with the Graco seat! I was looking for something that would still have a 5 point harness for now, and booster option for later. Only change I wish I could make is the clips for anchoring. These are the more basic hook style (which are hard to unhook) versus the quick release latch which we have on the extend2fit. Overall happy with the size and fit for our daughter.

Hard to tighten
May 7, 2022
After 6 months, I still find it difficult to tighten the harness. I also wish it had 2 cup holders. Also everything says the high back booster is over 40 lbs. But the instructions says 30. Itd be nice to know which. My all-in-one was a much better car seat.

Great booster
May 6, 2022
The product works great and looks great, I just wish there was more head padding so that when my child falls asleep they have something to rest their head on. Instead her head has no support while sleeping sitting up

No complaints

Nothing wrong with this carseat. Easy to install. Great for our 2 year old and looking forward to it growing with her. We also have the 4Ever car seat from Graco, this one is definitely not as nice in terms of the cushioning and materials, but I was expecting that. Good price point. Not super bulky.

Great Quality
April 26, 2022
The seat is great the only thing I would have liked or suggest is that the cup holder be on the left side of the carseat or the side that is faccing the middle of the back seat.
