Description

The Diono Radian 3RX is the original slim fit 3 across all-in-one convertible car seat, designed to protect from birth to booster seat (5 - 120 lb / 2.2 - 54 kg). Featuring 12 position adjustable head support, extended rear-facing up to 50 lb and steel reinforced frame, expect 10 years of safety from just one car seat. The Radian 3RX is designed and engineered to keep your child rear- facing for as long as possible up to 50 lb. The infant head and body support provides extra comfort in the early stages and can be easily removed as your infant transitions between rear and forward facing. As your child grows, the aluminum reinforced headrest can be adjusted to one of 12 positions for safety up to 57 tall. Built with a mechanically engineered, reinforced steel frame, made from automotive grade high strength steel, the Radian is always ready to shield and protect. And when your family grows, the slim-fit design will fit 3 across in most vehicles without compromising child safety or passenger comfort. Our SuperLATCH system (UAS Compatible) makes installation easy and super secure. For added parent convenience, the Radian 3RX features hard- wearing, easy remove covers. So, when the next journey gets messy, easily remove to machine wash. As travel car seat experts, Diono have naturally built in super portable features to the Radian 3RX with original fold for easy transport and storage and a steel reinforced cup holder to store essential road trip drinks and snacks. The Radian 3RX is also aircraft certified (FAA approved), so you can take safety with you wherever you go.

  • Love this carseat
My oldest child has this same one, I love this car seat. It’s heavy, but I like that. It’s very sturdy yet not too wide like other car seats. My kids sit comfortably in it, they don’t mind riding in it. I would absolutely buy again if I needed to.

  • Bought for the back seat of my BRZ, does everything I wanted!
Gratefully, I haven't had occasion to see how well this seat protects my child in an accident, though I'll be sure to update this review if such an unfortunate thing occurs. It's important to note that a disadvantage to having this seat in a vehicle that isn't garaged is that with consistent sun exposure the top of the liner was sunbleached within two weeks of purchase. It hasn't seemed to negatively affect the durability, but it's certainly obvious I've parked in the sun. I gave this seat five stars because it's comfortable for my child, it seems stout and secure even when compared to other child seats we own, and it fits in the tiny, beveled Alcantara and leather seating of my BRZ's back seat, WITHOUT DAMAGING THE SEAT. The fun little "Child on the Go" sign was a great and unexpected perk. If you have a 2+2 sports coupe, I would recommend this seat over any other... especially if you primarily park where there isn't consistent sun exposure. ... show more

  • One of the best
Color: Blue Sky
This car seat is slim, solid and very well designed. Storage on the back for the tether and child quick connect locks. Fits my 3 year old like a dream. Easy to hook up, besides being slightly heavy. The harness is high quality and my little guy is tucked in and well secured. Happy parent.

  • Great car seat
Bought a set for our twins, perfect for itty bitty premie newborns. Twins are going on three now and other then dirty boy fingers everywhere they have held up super well! Ordered another for our daughter (now 3 mo.) would definitely recommend! We have an express van and can put three side by side, the seats are tight together but it is possible with our vehicle. ... show more

  • perfect for nanna's car
This works great. I bought it for my mom to have one in her car. We also use it when we travel on airplanes as it's easy to get in and out.

  • I am loving this car seat except for one thing.
I love how slim and sleek the design and color is. I have a tiny little Honda Civic and need to fit 3 car seats across. I got this one for the one who is already forward facing. I love how the latches are very easy to connect and disconnect. However, the back is way too long to fit rear facing in this car. Graco came out with the True3fit LX. That one is about 4in shorter so it fits perfectly as a rear facing, is just as thin as the diono, and has similar latches. The one and only thing I’m not liking about the Graco one is that it only comes in one color, it’s a navy blue/grey/black combo. The infant car seat that I plan on getting is 17” in width, about the same as the other two. The infant car seat in the pictures is about 19” in width, despite one of the seats not being as slender as the other two, I can still fit all three in the back seat of my 2019 Honda Civic. ... show more

  • Slim yet comfortable seat!
I didn't expect to have to assemble the car seat, but it was simple. Installation in the car was also very easy. We have enough room for an adult to sit in the backseat, if necessary. My daughter seems pretty comfy - she fell asleep on her first ride in the new car seat! I would definitely recommend this brand and buy it again if I ever need another car seat. ... show more
