    • Love it!
Color: Hex 2.0
Love it! This was super easy to assemble (currently 39 weeks pregnant) and install. Our extend2fit was gross despite multiple efforts to clean it PLUS the buckle between the legs had become extremely difficult to clasp. My 4 year old has no problem buckling herself into this one. She can also get down out of it much easier. Love the no rethread. Cup holders detach for easier cleaning so that will be fantastic. It also fits her kids size owala bottle perfectly. Feels nice and cushioned. Hopefully this will last us longer than the extend2fit did! ... show more

    • A week in, and it still works great.
Color: Hex 2.0
The seat is great, once you get it in the car. Our kiddo is 3 years old, but outgrew his old car seat but just plain ole being too tall. Wanted something that had a 5 point so we can make will in to 4 years old before we switch to regular booster mode and this fit the bill. It goes together pretty easily. the hardest part is moving the buckle from the "smallest kid" hole to the "Big Kid" hole for the 5pt harness. Protip, push it from the back, don't pull it from the top. Everything clicks together in a satisfying way, and the seat adjustment is smooth. Easily installs with the latch system for booster mode. Our kid went from the infant seat to this one, and he likes sitting up more, and being able to see to the sides easier. I like that it is easy to move the shoulder straps to the side so he isn't sitting on them and having to fish them out each time. Also loosening the straps is silky instead of the tug of war we had with our old seats. The cup holders feel like it would take a concerted effort to remove. While they are removeable, I don't think you are going to bump them off. The cover removes easily if you pull the seat out of the car, it isn't a zipper, but the easy on and off is worth removing the seat to get it off. I think this should last us until our kiddos is old enough to no longer need a booster. ... show more

    • A Pleasant Surprise
Color: Hex 1.0
I must admit, I was pleasantly surprised by the quality of this car seat. It ticks off all the right boxes, making it a great choice for parents and caregivers alike. Firstly, installation was a breeze. The design and features allowed for easy and quick setup in any car. Moving it between vehicles was a hassle-free task, as it wasn't overly heavy or cumbersome. The comfort level of this car seat is remarkable. The ample padding provides a cozy and snug environment for the child, making long journeys much more enjoyable for them. Safety is a top priority, and I was pleased to find that this car seat excelled in securing the child properly. It offered the peace of mind I needed when driving, knowing that my little one was well-protected. One aspect that particularly impressed me was the price. While I usually lean towards more premium brands for my child, this Graco car seat proved to be a worthy contender. It delivers exceptional quality at a reasonable price point, making it an excellent value for the money. Honestly, I never thought I'd consider a Graco car seat, but this one changed my perception entirely. The brand has done an outstanding job with this product, and I can confidently recommend it to others. If you're on the lookout for a reliable, easy-to-use, and well-priced car seat, look no further! ... show more

    • I take car seats for children seriously and this is one of the best I have seen.
Color: Hex 2.0
Highly rated by Consumer Reports and Wirecutter but more importantly by my grandchild's parents. This is the best car seat I have ever put in a car. My Subaru Outback has the "Latch" system for securing car seats and it makes it very easy to put in and take out the car seat. With LATCH there is no fiddling with car's seat-belts, you just snap three latch buckles to the LATCH attachment points, tug on a couple of belts integral to the seat to cinch it down and you and your child are good to go. ... show more

    • Great compact car seat.
Color: Hex 1.0
Great car seat! I have been looking for more compact car seats since I’m now having to put 3 different car seats in one row. This is a great size and looks nice also!

I love Graco products. It has easy to use push button clips that secures the care seat well and makes it easy to install and remove which is a must for me. I would recommend this product.

This came so fast! I was so happy to receive it because it was a replacement after a car accident. Super easy to put together and install. I have weak hands due to autoimmune diseases and all components for buckling and unbuckling I’m capable of doing. My 4 yo can buckle herself into it as well. There’s very nice cushioning in it for comfort but not so much that it could compress and be a safety issue. ... show more

    • Love this seat
Color: Hex 2.0
Really glad I got this carseat, the material seems more water resistant then most which with a toddler is nice. I love that its a smaller size so it fits next to other carseats easily. I was struggling to find a 5 point harness that can become a seat belt booster also and this one can! Which save money down the road. I did alot of safety research on carseats and this one was one of the top rated ... show more
