Review: I like it but it's heavy and tricky to install - I got this for my youngest who sits in the middle with booster seats on each side for her brothers. It is narrower than the one it replaces and I really like the red color and design. It looks like a high quality car seat and feels premium. It looks great and fits great in my Range Rover Velar. Overall, I like it but there are a few things to consider: PROS 1. Great looking design 2. Premium feel 3. Easy for my 4-year-old daughter to buckler herself 4. Narrow 5. Comfortable for my daughter CONS 1. It's VERY heavy. If you have to take this seat out from time to time, that might be a concern. This is for my car but my wife would never go for a seat this heavy. It seems like it weighs twice as much as the older Maxi Cosi seat it replaces. If the weight of the seat is a concern, avoid this one. 2. There is nothing intuitive about installing this thing. I had to watch a YouTube video just to find the installation instructions. I'm not kidding - they are hidden in the back fabric and housing. Once you have the instructions, they are not much help. This illustrations are professionally drawn but hard to understand. Even getting the various straps out of the back plastic housings is tricky.
Review: Great for Tight Spaces and Growing Kids - This is an excellent car seat for a growing toddler or child. We loved it so much that we purchased one for every car, including the grandparents’. My son had difficulty getting in and out of his previous car seat and struggled with buckling, but he has completely mastered it with this one. He feels more independent and proud that he can get in and out on his own. Another big plus is how space-conscious this seat is. We can comfortably fit two car seats and a third person in the middle seat of our SUV, which is perfect when traveling with extra passengers. Installation is easy, making it simple to move between different vehicles if needed.

### ⭐⭐⭐⭐⭐ Fits 2 in a row with additional infant seat in Toyota Camry!
*by E***R on February 12, 2025*

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!
