Purchased for my toddler to switch her forward facing and wanted space for the car seat for her new baby brother. Fits great and my daughter loves it.

This review was collected as part of a promotion
I got this car seat because it fits well in my 3row SUV on my middle bench and allows me to pull the bench seat forward to access the back seats unlike the other car seats we had. My only complaint is I don't like the the cupholders stick out which the seat catches on but I can just pop that one out. Overall, this seat is pretty compact and easy to use and adjust.

Uncomfortable death trap
Good god if you love your children, don't buy this seat. The pictures are false advertising/fraudulent, see attached photos of what the seat actually looks like. It's unusable for my kids, the weird plastic pieces push down on their shoulders, and those pieces are absent from website photos. Would never have bought it if those pieces had been accurately represented. Also, see attached video of what Evenflo considers "successful installation. " Like I said, avoid if you want your children to survive in the event of a car accident.

GREAT customer service But HARD install
I literally cried installing this.

I bought an evenflo revolve 360 extend for my son.

We had the same problem with the new seat and so they offered us a different seat . We got this one and tbh the install is so hard I cried . I miss the revolve with its easy install.

Took me 30 minutes in the Florida heat to get it right. I also wish it had the…

Doesn’t seem to get super
Doesn’t seem to get super tight when placed in vehicles— especially when using the anchors. Really bummed because I was really looking forward to this car seat after all the reviews I looked into.
