DionoRadian 3R, 3-in-1 Convertible Car Seat, Rear Facing & Forward Facing, 10 Years 1 Car Seat, Slim Fit 3 Across, Jet Black

I would give this 4.5 stars if I could. It is one of the only seats that will fit my tall 7-year old boy that has a multi-point harness. It also has enhanced support for the head and neck (again, one of the only such models on the market that will fit a tall 7-year old).I say 4.5 instead of 5 because at least in a Tesla Model Y, it is impossible to get this seat 100% tight and immobile. That's a bit annoying and different from the baby / toddler seat I had before. However, compared to the standard issue "booster seat" that my boy could legally use, I am convinced that this provides much better protection even with a bit of "wiggle."

Great car seat! It’s sturdy & very sheik I love the easy cleaning fabric it has, it is very heavy which makes me feel like my baby is safe in it! It’s got adjustable shoulder straps & head rest adjustments as well so it can grow with your baby. The seat part also has side adjustments so it can be narrow or wider which is a neat feature! I won’t be using it for travel but it folds up and could be easy to transport if you can carry the heavy weight of it. For the price of this car seat it was a steal!!! We spent double on a Gracie brand before and i feel this car seat is much safer, it’s also roll over tested which is great because not many car seats have that. I will say the cup holders are terrible they fall out very easily but I rather my kid be safe than have a cup holder!!! I was able to fit 2 of these car seats in with a Doona in my Ford Escape 2018 which was suppose to be impossible but the fact of how compact it is made it possible, my boys also say it’s very comfortable which is a huge bonus! Definitely a must buy car seat!!!

Diono products have been a life saver for fitting my 3 kids in one row. I have 3 rows, but prefer having my kids farther from the rear of the vehicle in the case of a collision, and I also like having the trunk space.

I have a 2022 kia Sorrento and I’m about to be a mom of 3under 4 and I really wanted all my kids in the middle row but I was able to with the Graco slim fits and the infant car seat as while but it fits great with a little room to spare to!

Car seat is very heavy. Simple to install looks sleek in the car it says convenient for travel but with how heavy it is I don’t agree at all. I couldn’t imagine traveling with this!

Able to fit 2 dionos and a doona into my toyota corolla. Only carseat with such a slimfit design. Not the most comfortable headrest but the slim design is worth it.

Amazing quality! Easy to assemble super safe and easy to clean! I love this brand!

Easy to install, fits 3 across in our mid-size suv, very comfortable for long rides for our kids, a little on the heavy side but that comes with a durable car seat. Colors are what we ordered. Easy to clean. Easy to adjust straps.
