The fully integrated steel frame is riveted together with thicker engineered plastic to withstand severe crash forces.

What Other Parents Have to Say...

To me, this seat is the best bang for your buck as it lasts through all the stages of riding in the car from coming home till going to college (hehe just kidding but you get the idea.)

- Naturally Cracked radian rXT review

I must admit that this car seat (Rainier) is kind of heavy. BUT, you can tell that it was made to the highest standards a car seat can be held.
