Fits 2 in a row with additional infant seat in Toyota Camry!
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 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.

Easy to move from one vehicle to the other i
Bought this to use in the car and side by side for granddaughter!! The ease of moving it from one to the other is great! The multiple locks and latches are nice! Fits well and slim in the car. Looks great and super sturdy.

Fits 3 wide, Great quality worth the $
With the birth of our daughter I needed to go 3 wide on the car seats, which I was told was impossible for my Dodge Charger. Well I purchased 2 of these Diono Radian 3R seats and it worked. The seats are really high quality, loved the added harness protection for toddlers who meet the weight requirement. High quality product and my 2 toddlers are comfortable in them.

Great car seat, super heavy for travel.
We needed to upgrade our travel car seat and loved that this one folded up nice and compact. Love that it is FAA approved (that was a must for us) It worked really well in the rental car. Our buddy was quite comfortable. Set up was very easy. It is easy to get him in. The release for the belt is kind of tricky to find but easy to use once you got it. We got this one for the same price as the lower model on prime day and are so glad we did the safety plus just for that added comfort. The only drawback for travel is that it is HEAVY!!!

Great quality, easy to install and use, and great customer service!
LOVE this car seat. I bought the first one, installed, used, loved it. Was thinking about getting a second one for another car of ours so we wouldn't have to move back and forth between. I left a nice review and mentioned I was thinking about a second one, and the company actually replied back thanking me, and offering me a 20% discount! Of course I took them up on it. This car seat works very well with our grandson that has brittle bone disease and needs to be handled very carefully. Getting him in and out is much easier than our old one, and he's happy in it too. Now between our house and his own house, he has 4 of these seats. Thank you again!!

Absolutely life changer!
I have 3 littles in car seats. I bought a mini van for our growing family, only to find that with most car seats would take my 3seater backseat room entirely up by only 2 car seats and not allow room for another car seat or a small person to fit. I came across these car seats that claim to fit 3-across. Was skeptical to purchase 3 of them at once because let’s face it it’s a big purchase. I took a chance and 🤞🏼 that they would fit. They arrived and I was very impressed by the quality of the car seats and then I installed them and my goodness, they fit!! I’m so happy 😀 I can finally use the 3rd seat space in the back seat, which is why I bought the van for. Absolutely, great job Diono, you nailed it! 🩷 Attaching before and after photos.

Bought 2 & would buy more
Super sleek, safe & sturdy. It’s so easy to strap the kids in & adjust knowing they’re safe & secure. I love the strap pads that would 💯 prevent any necks getting slit in an accident. It’s easy to take in & out but it’s definitely not recommended as a grab & go car seat. It’s solid.. the steele frame makes it pretty heavy so as long as you aren’t puny, you’ll be fine. You might break a sweat, transporting it and putting it in another car, but would you rather than be safe or in a cheap inexpensive Walmart car seat with straps that constantly twist. Super comfortable, apparently. My son usually falls asleep before we even get out of town. I bought one for my mom’s car and my husbands mom’s car. We have a different Dion model in ours but this one is easier to use honestly..

Ocupas ser un Ingeniero Aeronautico o automotriz para Instalarlo. Es demasiado Dificil su instalación. Pero brinda buena protección al BB

This was our first car seat purchase of this brand, and we’re so happy with it! Our child loves it even on long drives. It was super easy to install, and we felt confident choosing it after reading the strong safety ratings. It’s also easy to clean the cover comes off easily and can be tossed in the wash, then air-dried. It’s narrow enough to fit multiple seats across and works great rear-facing in smaller vehicles as well. We liked it so much, we bought a second one for our other vehicle. Great quality at a reasonable price highly recommend!

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

I bought this car seat as a second to have when we got a second vehicle. However I liked it so much and so did our (rear facing, 21lb, 19 months) daughter that this is now the main car seat, and my husbands truck has the Grace Forever. Not that there is anything wrong with the graco, it’s just she looks so much more comfortable in the Diono. It’s slim and sleek, fun colour, she sleeps very well in it and her head does not hang uncomfortably like in the graco. There is another Diono model with all the cushions and I went back and forth on this one and that, honestly, this one gets the job done well. Maybe if she was an infant I would purchase the one with all the cushions but there is seriously no need. The memory foam on the buckle straps are perfect for protecting the neck from rubbing and give a really nice cushion without preventing proper tightening. I would say that only downside I’m seeing is in rear facing, it’s a tall seat and it reclines very well so you may have issues in a smaller car or if the seat has to be behind a tall person. We have a Honda Odyssey and it does prevent the front passenger from having ample leg room or any bit of reclining. But that’s just temporary! I say go for it!
