Life is complicated enough, and that’s why here at Diono we carefully craft our products to be intuitive and as easy to use as possible while providing the optimum level of safety and security for your little ones. Trusted by over a million parents, the Diono Radian 3R is our flagship all-in-one convertible car seat, designed to fit 3 across, without sacrificing safety or passenger comfort. We have spent years perfecting protection to help parents keep their children traveling the safest way, for as long as possible – our Radian series is lovingly engineered with the famous Diono Steel Core that provides an unyielding structure to protect and shield, and extended rear-facing capabilities, so you can expect 10 years of safety from just one car seat. Our unique SuperLATCH system makes installation easy and secure with an audible “click”. The Diono Radian 3R surrounds your child in overprotective, strong materials giving you peace of mind wherever life takes you (including in the air: the Radian 3R is aircraft certified / FAA approved), so you can take safety with you wherever you go. We’ve thought of everything, so you don’t have to.


  • THREE'S NOT A CROWD: Sleek design allows for a 3-across fit in most family-sized vehicles. The slim, all-in-one design works rear-facing, forward-facing and as a booster, fitting your little ones from 5 to 120-pounds.
  • SOLID SIDE PROTECTION: Additional impact protection with aluminum reinforced frame and energy absorbing EPS foam.
  • REAR-FACING LONGER: Keep your infant rear-facing longer, the safest position to travel up to 40-pounds.
  • TRAVEL THE WORLD: Super portable and folds flat with available carry straps for easy travel and transporting with ease, FAA approved for use on aircraft.
  • EASY INSTALLATION: Our SuperLATCH system makes installation quick and easy with an audible click. We offer a choice of installations including a versatile top tether for both rear and forward-facing installation.
