RadianXTsl is a convertible car seat for rear-facing children 5 - 45 lbs and forward-facing children 20-80 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.

A height adjustable, aluminum-reinforced head support and protective EPS foam surround the childs head and body to provide the most complete side impact protection of any car seat, and the SafeStop energy absorbing harness system. Radians low profile offers easy child boarding and its unique design provides more shoulder room yet still fits 3-across in a car. Memory foam padding and infant support pillows provide additional comfort. All this and RadianXTsl can fold flat for convenient travel and storage.
