Product description

Style:NEW  |  Color:Blue Sky

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 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.

3.0 out of 5 stars Wrong color but still a great car seat
By Amazon Customer on August 17, 2021
I love the Diono car seat for the safety, and that I can put 3 side by side, and lastly that it is good for 10 years. However, my order said SKY BLUE…… what happened? My delivered box says Pink Blossom. Good thing I am a child care provider so it is not simply for a specific boy or girl. Pricey but great car seat, even in the wrong color!
