A high-capacity car seat has to be amazingly strong for a big child, but properly designed to provide the best performance for a small child.

It has to offer advanced safety features, the correct fit, plenty of comfort and proper support for a child at each stage. And it definitely needs to have the right styling because a 5 year old does not want to ride in a baby seat.

Finally, safety has to be convenient and easy to use, everyday. Radian80 does all this and more.

Radian's patented steel frame means no bulky plastic structure. Compared to other car seats, Radian offers more shoulder room, more leg support and fits three across in a car.
