Great transition car seat!

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!

Great seats!

We purchased two new car seats for our bigger kids, and were impressed with Graco's high marks for safety and comfort. The seats took a little more effort to install (it helped watching videos to get the seats installed tightly, as at first there was too much movement) but once properly set up, the kids loved their new seats and both promptly fell asleep! Recommended!

Love this car seat. Had the older version for my older kids and hit the reset button on my 18 year term and got a transitions graco car seat and it's awful. My toddler who loves to travel cried non stop in it so I ordered this one again and so far it's great.

Car seat that turns into a booster

I use this car seat when I have my grandkids with me. It's easy to install, and I like that it has a five-point harness for safety. Once I had it installed, it stayed in place. My grandchild said she likes her car seat and said it's comfortable. It has a washable cover and two cup holders, although one doesn't stay attached, which is the one thing I don't like.

Good option for growing toddler

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.

Great carseat!

Love this carsest for my car in my scion XB. The only downfall is it tall and blocks the view in my husbands nissan frontier. But I feel the truck doesnt have much head room compared to most vehicles (my xb has more). And I dont know of any other options that would provide these features for my tall child for this price. If your vehicle doesn't have much head space, this might block your view more. However, not sure there is anything else available in a highback booster/harness that would be shorter. Other than this problem in my husband's truck, this carseat is perfect.

Latch system

I bought this as a second seat for grandparents car. I love how lightweight it is and easy to install. My daughter loves the little side pockets in the arm rests. They are the perfect size for a stuffed buddy. The only thing I did not look at when ordering was the metal hooks on the latch system. Our other graco car seat has the latch with the easy release button latches. This car seat has the flat metal hooks you have to work with a little to get out.

Comfortably fits heavier set kiddos

I have been looking for a 5 point harness seat for my 4 year old that weighs 65 pounds but every seat we tried was too small. I wasn't ready to move him into a booster with lap belt so we gave this seat a try and we're so thankful we did! Theres still plenty of room to grow and my momma heart is happy knowing he is safely buckled in his seat.

Great car seat

[This review was collected as part of a promotion.] The seat is very comfortable. I wasn't expecting the amount of cushion that came with the car seat with its price range. Not sure how long the vision will last but it is good right now. It would have been better if it was a bit thicker. Also, it was very easy to secured the car seat to the car. Tunneling the car seatbelt behind the car seat was so easy, I had to keep checking if it was tunneled correctly. My previous car seat was a pain to be secured down
