We bought 2 of these to fit in the backseat of our 2010 Toyota Camry. 1 rear facing, middle forward facing, next to infant (Uppababy Mesa) seat. Middle forward facing was the only way it would fit. Pro’s: slim, sturdy, easy for our kids to get into themselves, latch system is easy/works well. Good customer service from Diono. Our first one didn’t have the rear-facing piece in the box. Cons: * Very heavy! * Tall backside. Check your car seat manual whether a car seat is allowed to touch/rest against the front seat (if rear facing). Now having moved one to the middle back seat (forward facing) on our Honda Odyssey, it sits higher and blocks the rearview a bit. Wasn’t an issue in the Camry. No cupholders- fine, since that wouldn’t fit anyway. Not as much padding, so perhaps less comfortable, but both our kids are fine in them. Overal conclusion: great car seat if you have a tight back seat!

Great chair struggled to get a chair with a 5 point harness for my 5year old who can't use a normal seatbelt.

These seats are great. I have six of them. Three kids, three vehicles, They are easy to fold, easy to swap in and out and they fit three wide in my sedan. There are very few car seats that fit three wide. I keep buying the same seats, with the same color so when I rotate them between vehicles the children aren't picky as to " that's my seat"
