News & Press
radian® Q series has landed

As pioneers of the original All-in-One convertible car seat, the diono radian® R series can already be found in over a million cars across America.

For our 20th anniversary, the team have not only added some great upgrades to the family favorite but are set to welcome the next generation in a long-standing legacy.



  • Safe+™ engineering
  • Complete newborn rear-facing protection
  • Safe+™ steel anti-rebound bar
  • Safe+™ side impact protection
  • 23 upgrades in safety, comfort, testing & functionality
  • 90% components upgraded

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.

We are delighted to launch the radian® Q series on such a landmark year for our business. We’ve taken everything we’ve learned over the past 20 years in car seat design and engineering, to provide parents with the ultimate 3 across All-in-One car seat.
The radian® Q series marks the first featuring all-new Diono Safe+™ engineering promise that furthers our commitment to child safety. As we move forward our mission continues to always go above and beyond to deliver products that serve and protect.
