Serious safety and comfort. Our radian® r120 convertible car seat has a full steel frame and aluminum reinforced sides to maximize protection. The slim, all-in-one design works rear-facing, forward-facing and as a booster fitting kids from 5-120 pounds.
Some say three’s a crowd. We say, the more the merrier! Radian® r120 car seats fit 3-across in most mid-size vehicles.
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.
