The radian Q launches the diono Safe+ engineering promise. All Radian Q series seats are subjected to a combination of the most rigorous crash tests; front, rear, and side impacts, and rollover tests to make sure we have the safest seats possible.
Diono has always promoted rear-facing travel and the Radian Q series takes rear-facing protection to new levels. The Q series provides complete rear-facing protection for ultimate safety up to 50 lb, (approx. 4 years old) so parents can keep their child rear-facing for as long as possible.
The all new Safe+™ steel anti-rebound bar enhances rear-facing protection, preventing the seat from rebounding or “bouncing back” in the event of a collision, reducing rebound rotation by a huge 50%.
As they transition to forward-facing, the Safe+™ protection grows too, with easy-adjust 12 position headrest that is contoured to improve child head containment and provides a 22% increase in occupancy range from the radian R series.
