DIONO Radian 3 R

Life is complicated enough that’s why here at Diono we carefully craft our products to be intuitive and as easy to use as possible while still providing the optimum level of safety and security for your little ones. Our Superlatch™ system makes installation easy and secure. The Diono Radian® 3 R surrounds your child in overprotective, strong materials giving you peace of mind wherever life takes you on the special journey that is parenthood. We’ve thought of everything so you don’t have to.

  • Joy of the journey: From birth, keep your little one rear-facing longer to 40 lbs, traveling safely. As they grow to 100 lbs (10 years approx.) our long-range lifespan protects your child facing forwards. Peace of mind for you, we’ve thought of everything so you don’t have to.


  • Lovingly engineered: The radian® 3 r is fabricated using super strong automotive high strength steel, engineered into a dual spine. This unique core manages and dissipates energy and provides an unyielding structure to protect your baby. Our audible click SuperLatch system makes installation easy and quick.
