Diono Radian 3 QXT is the ultimate 3 across All-in-One car seat from birth to booster (4 – 120 lbs) that features 4 stages of complete rear-facing 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 lbs (approx. 4 years old).
