Diono Radian 3R SafePlus - Black

The Original 3-Across All-in-One Car Seat upgraded edition. Updated with 12 improvements from the original Radian 3R.

The Original 3-Across All-in-One Car Seat upgraded edition. The All-in-One Car Seat just got better. Updated with 12 improvements from the original Radian 3R, the Diono Radian 3R SafePlus features Diono SafePlus engineering, SafePlus Easy-Adjust 12 Position Headrest and improved SafePlus Side Impact Protection for complete protection from birth to booster (now suitable from 1.8 – 54 kg/4 – 120 lb.)

Lovingly engineered with the improved SafePlus Steel-Core, and as both a rear and forward-facing convertible car seat, the Radian 3R SafePlus protects as they grow, with SafePlus Easy-Adjust 12 Position Headrest. The new and improved Radian 3R SafePlus features energy-absorbing Side Impact Protection and extended side walls to reduce the impact of side crashes, all without affecting our slim fit 3-Across design in most midsize vehicles. The Radian 3R SafePlus comes with Anti-Rebound Bar slots for optional Anti-Rebound Bar (sold separately) for added rear-facing safety.

Radian 3R SafePlus All-in-One Convertible Car Seat is subjected to a combination of the most rigorous crash tests to ensure the safest seat possible. In addition to our regular extensive crash testing, we test over and above – including roll-over and side-impact tests, to achieve results above and beyond the current Federal standards. Our Easy-Click SuperLATCH system (UAS Compatible) makes installation easy and super secure.

Radian 3R SafePlus now comes with an XL Steel-Reinforced Cup Holder to keep drinks and snacks handy on the go, and as travel car seat experts, Diono has naturally built-in super portable and convenient features to the Radian 3R SafePlus with travel fold for easy transport and storage and easy remove machine washable covers. The radian is also aircraft certified (FAA approved), so you can take safety with you wherever you go.
