Diono's Original 3-Across All-in-One Car Seat has been upgraded.

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 4 - 120 lb / 1.8 - 54 kg.)

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 the 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 seperately) for added rear-facing safety.

In addition to Diono's regular extensive crash testing, they test over and above - including roll-over and side-impact tests, to achieve results above and beyond the current Federal standards.

The 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.
