Great Seat

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!

Space saver! Toddler approved!

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.

It’s big!!

I like this seat, but it’s HUGE and heavy!! Made great but can be bulky. Just keep that in mind. But these worked without seat is comfy and my child loves it. Seems very safe!!

Extremely heavy, overly complicated and straps won't tighten properly on smaller children.

Purchased this because of the narrow width to use as a travel car-seat on a commercial airline and with a rental car. I would strongly recommend against buying this if you intend to travel with it. It is extremely heavy and nearly impossible to maneuver on board an airplane. It is supposed to be good for children from birth to age 10, but because the straps have to be made to fit bigger kids, they won't tighten properly on a small toddler. I took the cover off to wash it prior to use, and needed the have the instructional video playing over and over to understand all the steps to disassemble and reassemble the seat. Replaced it with a much simpler and lighter carseat for travel.

Best car seat I have!

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.

Safety is everything

My baby is so secure and safe in the car seat. I love the quality and I feel good about the car seat. She’s in. I love the color as well.

Solid Narrow Seat

Solid seat, not as heavy as other reviews made it out to be. This is not a pumpkin seat so expect it to be heavier than those. Directions for installation are not detailed enough for rear facing in my opinion, but that's what YouTube is for lol. Very happy with purchase so far
