    • 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

    • Diono Radian 3R - A Game-Changer in Car Seat Comfort and Safety!
Style: Radian 3R Fits 3 Across Color: Red Cherry
The Diono Radian 3R 3-in-1 Convertible Car Seat has proven to be an absolute game-changer for our family, and my son absolutely loves it! The versatility of this car seat is outstanding – from rear-facing to forward-facing, it's designed to accommodate different stages of a child's growth. The 10-year lifespan is a fantastic feature, providing peace of mind knowing that it will last through various developmental milestones. My son finds the seat incredibly comfortable, and the plush padding adds an extra layer of coziness. The reinforced steel frame gives a sense of security, and the installation process was surprisingly straightforward, thanks to the clear instructions provided. What sets the Diono Radian 3R apart is its slim design, making it a perfect fit even in compact cars without compromising safety. The adjustable headrest and harness system ensure a snug and secure fit as my son continues to grow. As a parent, I appreciate the ease of cleaning – the fabric is removable and machine washable, a lifesaver for those inevitable spills and messes. If you're in search of a convertible car seat that prioritizes both comfort and safety, the Diono Radian 3R is an excellent choice. It has made our car journeys much more enjoyable for my son, and as a parent, I couldn't be happier with this purchase! 🚗👶🌟 #DionoRadian3R #ConvertibleCarSeat #SafetyFirst ... show more

    • Great car seat!
Style: Radian 3R Fits 3 Across Color: Gray Slate
Love the compact size of this carseat. We bought it for my husband's sedan so we can fit this seat for our 5 year old, a booster for our 8 year old and an infant carseat for our 4 month old in the back seat. It's still a little snug but it works. My only complaint is that the car seat is supper heavy, but it's really not that big of a deal. Love the fact that you can fold the seat up as well. ... show more

    • Robust car seat, great size
Style: Radian 3R SafePlus Fits 3 Across Color: Pink Cotton Candy
Very robust car seat, tall and narrow size means it can fit with other seats in the row. Latch system is easy to figure out. There is more support than our old car seat. But, this car seat is heavy. All the weight is on the bottom. While good for stability, it was a pain when assembling the car seat, and when having to install. Overall, happy with the purchase, and would likely buy again. ... show more

    • Slim seat for tight spaces
Style: Radian 3R Fits 3 Across Color: Blue Sky
Not sure why all these years I didn't consider this brand over the Graco seats. Cushion and belts are much better than my 4 n1 Graco seat. Lower seating position making it easier to seat my child. Very well built and sturdy.

Style: Radian 3R Fits 3 Across Color: Pink Blossom
Review Image by Vett Garcia Vett Garcia
I switched from Graco to this one once my child moved to forward facing, but that wasn't my plan. I initially bought this as my airport/travel chair, but when it arrived and I felt how heavy it was, that was out but I decided to not return it and I'm so glad I didn't. My child is long and I felt she looked cramped in Graco. So when I changed her position, I took the Diono to the fire department to install (if you don't know, they do this for free) and they said that Diono was the creme de la creme, the best in safety. They said the weight adds value. They installed it SO TIGHT, that I feel soooo secure in the event of an accident that the baby will be alright. They said it's a bit difficult to install, but it was worth the work. It is the last seat I'll buy bc it lasts until 120lbs. It's slim in the car. I'm so pleased and the color is cute!! ... show more

Style: Radian 3R Fits 3 Across Color: Black Jet
We have 3 kids and have fit all three dionos in our Tacoma and outlander. I love this car seat. It’s safe, easy to adjust, sturdy, and saves us room! It’s a bit heavy to travel with, but it’s that metal plate in the middle which I love for safety. It’s comfortable since my kids haven’t complained.
