The ultimate 3 across All-in-One car seat from birth to booster (4 - 120 lb / 1.8 - 54 kg). Featuring 4 stages of complete newborn protection and all new Diono Safe+ engineering to provide the next generation in car seat safety.

From baby's first journey the radian 3QXT provides complete newborn protection, with Safe+ newborn travel high wedge, Safe+ newborn protection insert, Safe+ 2-in-1 infant positioning liner and Safe+ newborn harness pads to provide a custom fit from birth.

As your child grows the Safe+ steel anti-rebound increases stability and reduces rebound rotation by up to 50%, so you can keep them safely rear facing for longer, up to 50 lb (approx. 4 years old).

Engineered following the latest European research and technology in crash energy management, the radian 3QXT features 8 layers of side impact protection, that includes a removable Safe+ side impact management pod, constructed to channel energy around the back of the car seat and away from the child in the event of a side impact. This forms two of the 8 layers of interlocking EPS and EPP foam, high density plastic and steel reinforcement to create ultimate side impact protection, without compromising 3 across fit in most midsize vehicles.

As they transition to forward facing, the Safe+ easy adjust 12 position headrest is contoured to improve child head containment and provides a 22% increase in occupancy range from the radian R series.

All of these great features have been combined with Safe+ engineering, with the 3QXT subjected to a combination of the most rigorous crash tests; front, rear, and side impacts, and rollover test to ensure the safest seat possible.

Parents can also expect the travel friendly traits Diono is famous for, including convenient fold and FAA approval for use on an aircraft. So, no matter where you go you can take Diono safety with you.
