    • Fits 2 in a row with additional infant seat in Toyota Camry!
Style: Radian 3R Fits 3 Across Color: Black Jet
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! ... show more

    • Safe, affordable, & comfort all in one!!!
Style: Radian 3R SafePlus Fits 3 Across Color: Black Jet
Review Image by Darlene Darlene
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!!! ... show more

    • Favorite Car seat
This is my favorite car seat. I am soon going to have 3 under 3. I am planning on switching all car seat to this one. They fit in all 3 of our vehicles nicely and securely. (We have a SUV, Sudan, and Truck). Which we have had problems with other brands not being secure. They are really easy to move from car to car. They are a little heavy but I don’t find that to be a problem. I find there price to be very reasonable. I have fortunately been able to buy both of mine when they were on sale. ... show more

    • Diono Radian 3R: A Safe and Space-Saving Car Seat for Long-Term Use
Style: Radian 3R Fits 3 Across Color: Gray Slate
We absolutely love our Diono Radian 3R! It's been a fantastic car seat for our child, lasting from infancy all the way to booster use. Here's why it gets 5 stars: Space-Saving Design: This car seat is a dream for tight spaces. Its slim design allows us to fit 3 car seats across our mid-size car, perfect for families with multiple children. Long-Lasting Value: This car seat truly grows with your child. It transitions seamlessly from rear-facing for newborns (up to 50 lbs) to forward-facing (up to 100 lbs) and then to a booster seat (up to 120 lbs). It's a one-time investment that lasts for years. Comfort & Safety: Our child finds the Radian 3R very comfortable, with breathable fabric and a well-padded design. Plus, Diono's safety record and features like the steel-reinforced frame give us peace of mind. Easy to Use: Installation with SuperLatch was a breeze, and switching between rear-facing and forward-facing is simple. The harness is easy to adjust and the removable cup holders are a convenient touch. Easy to Clean: The Diono Radian 3R's machine-washable fabrics make cleaning up spills and messes a breeze. If you're looking for a convertible car seat that's safe, space-saving, comfortable, and built to last, the Diono Radian 3R is an excellent choice! ... show more

    • Difficult installation
It was time for my little one to upgrade from the basic infant seat, and I was looking for something that would fit her until she no longer needs a car seat/booster but still needed it to be affordable and in our budget. After looking at several other options, this seemed to fit the bill the best. It's very sturdy, and baby loves sitting in it. She's still rear-facing, and loves the extra room she has compared to her old seat. The only complaint was the difficulty we had figuring out how to install it in our vehicle. It took my partner and I both quite a bit of time, and found the manual to be little to no help. Once we finally figured it out, though, it seems very secure and doesn't wiggle or move around at all, so we do feel confident about baby being safe ... show more

    • Amazing carseat!
Style: Radian 3R Fits 3 Across Color: Black Jet
Review Image by Jarett Sisk Jarett Sisk
We have two of these carseats now and absolutely love them. They are slim and provide a lot of room for both the child using the carseat and the person sitting next to the car seat. I love how these carseats feel open and not so enclosed for the child. The car seat itself is very easy to install correctly and the cover is easily removable and reattachable for easy cleaning. The padding is great and it feels really secure and has great stability. Overall great quality. The only thing I wish that was different, is i wish these came with at least one cup holder. These are the only carseats I love to use for forward facing kids! ... show more

    • Lots of bang for your buck
This is a very sturdy car seat. It is also the only car seat that I have seen that folds for storage. It is great for small children but large enough for older children. My 7 year old even fits comfortably. It is a great seat that will last many years!

    • Love!
Love this brand of car seat. The safety aspect is why I went this brand, love that it’s narrow and you can fit 3 across. Cleaning this car seat is a breeze, the cover comes off for it to be washed. I have 2 of this exact one and then a high back booster of the same brand. Great quality car seats, easy to install, easy to clean. Highly recommend this brand to anyone with littles. ... show more
