Your child’s security is our top priority. We engineered our radian® 3rXT with premium, innovative features like a steel alloy frame, aluminum reinforced sidewalls, energy absorbing EPS foam and a reinforced adjustable head support to keep your little one protected and comfortable.
Some say three’s a crowd. We say, the more the merrier! Our radian® 3rXT car seats fit 3-across in most mid-size vehicles.
The radian® 3rXT keeps children comfortably rear-facing from 5-45 pounds for the safest possible position. Premium, plush head and body support cushions are included for newborns and infants.
Room to grow
Accommodates forward-facing children up to 65 pounds in a 5-point harness and converts to booster mode for kids 50-120 pounds. The aluminum reinforced, adjustable head support and sidewalls provide additional side impact protection.
Worth the Weight
Our convertible car seats are made from steel for safety you can feel. The fully integrated steel frame is wrapped in thick engineered plastic to withstand severe crash forces. Deep, aluminum reinforced sidewalls provide excellent side impact protection, while energy absorbing EPS foam surrounds your child for ultimate safety. Diono car seats are definitely worth the weight.
