I have two of these car seats, and they’re excellent! The durability and sturdiness make me feel confident my kids are safe—truly built to last. The quality is outstanding, and I love that it grows with them, making it a great long-term investment. The only downside is that it’s on the heavier side, so if you plan on traveling a lot, you might want to consider something lighter. But for everyday use, it’s one of the best and safest car seats out there.

My sister had one that we used on vacation and we loved it. Very sturdy, a lot of side support and it will grow with her. It is a little on the heavier side. But still worth getting.

This is an amazing car seat. I was in an accident with a previous car seat that saved my two year old. It was a cheap one I got on sale so for the new one I wanted something with great reviews and that was known for its safety. I feel so much safer with her in this car seat. Installing is typical to others. Not too hard but you definitely want to read your manual and maybe watch an installation video. It fits great in the middle seat with plenty of room for two other passengers on each side. The seat is more narrow than others with adjustable sides. My daughter seems to be comfortable and I'm at ease knowing she's safe. The only thing I'd say about this car seat is it is HEAVY!! we traveled to the airport with it and carrying it around by itself was horrible. I recommend buying the separate carrying case if you do any sort of traveling.

Love the car seat! My husband and I have used the evenflo 360 revolve gold since my daughter turned 1. She’s 3 going on 4 and we have a baby boy now who will inherit her revolve 360 seat. We decided to look for a car seat that was easy for my toddler to get in on her own without having to carry her into the seat and a car seat that was a space saver. This one did the trick it’s so much leaner and easy to adjust the buckles. My daughter does it on her own compared to her old one. What I will say is I don’t move the car seat at all so weight wise I wouldn’t be able to comment but when installing it wasn’t super heavy but it felt super sturdy. My only complaint is the cup holder wish it was built in but I understand it’s detachable to save space but works well! My husband didn’t have any issues with installation of the car seat he said it was straight forward for forward facing. One last thing my daughter’s head doesn’t hang when asleep it’s very rare compared to her revolve 360 that would occur always.

Very sturdy and seems to be really safe. I like how long we will be able to use this baby seat. Difficult to install but after several tries we got it in. My car is a little small (compact suv) but I think most cars will be tight when it is in rear facing position. Overall happy and will likely buy another for the other car. Did not want to have to worry about buying a different seat for different stages of life so invested in this one.

Nice, heavy, sturdy, comfy! My son is disabled & cannot sit in the vehicle seat without extra support. He was getting too big for a “regular” car seat. This seat is bigger & has a larger weight/height capacity. It is that perfect size for him & he looks comfy sitting in it! Comes with extra parts. Pay attention to what they are. Some are only needed for smaller children & reveres facing options. Scan the bar code on the paper in the box to understand assembly!

Doesn’t fit in two of our vehicles in rear facing mode. Apparently after having to watch videos on install I need a separate product Angle Adjuster to possibly make it fit in a correct position and not brace the seat behind it. Too big and too heavy, honestly too expensive, just to have to buy more for it, hard to install. Ridiculous. Returning it.
