Pin It

The Diono Radian RXT car seats are designed with your child's security and safety as top priorities. Premium materials and thoughtful safety features like a steel alloy frame, aluminum reinforced side walls, energy absorbing EPS foam, memory foam and a five-point harness put your mind at ease as your little one travels safely in style and comfort. The reinforced adjustable head support provides additional side impact protection. And if you want to avoid those bulky car seats, look no further as the sleek and narrow design of the Radian rXT allows for a 3-across fit or plenty of room for passengers. Our cover designs are inspired but European fashion, and more comfortable with soft fabrics that offer increased longevity and durability.
