    • 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

    • Safety for my Grandchildren
Style: Radian 3R Fits 3 Across Color: Blue Sky
This is my 3rd purchase, one for each of my grandchildren. These fit all the different ages and stages of growing children. They are narrow like advertising so you could fit 3 across a back seat, but the child has plent of room and sits comfortably. They are heavy so moving them when needed is a work out, that is what makes them safe the steel construction. ... show more

So far opening this car seat I couldn't complaint. First the colors are very vibrant...the car seat stands out it's a beautiful car seat. NOW.......the thing is very very heavy!!! Most likely because of the automotive steel core but yeah it's heavy. I bought because when they said it's convertible I can close it and then seeing some people carry it like a backpack they had me sold since I take UBER a lot but there's no way I'm gonna put this on my back is heavy lol.....but it's a beautiful well made car seat. My baby boy loveeeeeessss it! Transition from a baby car seat to a big boy carseat ❤️ ... show more

    • Don't hesitate!!!
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

    • Difficult installation
Style: Radian 3R Fits 3 Across Color: Red Cherry
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
