The ultimate 3 across All-in-One car seat from birth to booster (4 – 120 lbs. / 1.8 – 54 kg). Featuring 3 stages of complete rear-facing protection and all new Diono Secure+ engineering to give you the next generation in car seat safety.
From baby’s first journey the radian 3QX provides complete protection, with Secure+ newborn go back and forth high wedge, Secure+ 2-in-1 infant positioning liner and Secure+ Anti-slip harness pads for added comfort and safety.
As your child grows the Secure+ steel anti-rebound bar increases stability and reduces rebound rotation by up to 50%, so you’ll be able to keep them safely rear-facing for longer, up to 50 lbs. (approx. 4 years old). Engineered following the recent European research and technology in crash energy management, the radian 3QX features 6 layers of side affect protection. Interlocking EPS and EPP foam, high density plastic and steel reinforcement combine to create ultimate side affect protection, without compromising 3 across fit in most midsize vehicles. As they transition to forward-facing, the Secure+ easy adjust 12 position headrest is contoured to make stronger 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 Secure+ engineering, with the 3QX subjected to a combination of the most rigorous crash tests; including side impacts and rollover test to verify the safest seat conceivable.
Parents can also expect the go back and forth friendly traits Diono is famous for, including convenient fold and FAA approval for use on an aircraft. So, no matter where you go you’ll be able to take Diono safety with you.
