Radian80sl is a convertible car seat for rear-facing children 5 - 45 lbs and forward-facing children up to 80 lbs in a 5-point harness. Its steel alloy frame is NCAP crash tested making it the strongest car seat in the world. Our SuperLA TCH system ensures the easiest installation possible using the vehicle’s lower anchors up to 80 lbs – no seat belt required.

Radian80sl features reinforced sides and protective EPS foam panels for side impact protection and the SafeStop energy-absorbing harness system for enhanced safety. The low profile offers easy child boarding and its unique design provides more shoulder room yet still fits 3-across in a mid-size car.
