The next generation Diono Radian All-in-One Convertible transforms as your child grows from infant to booster for 10 years of us (4 – 120 lbs / 1.8 – 54 kg). Upgraded with 20 improvements from the much-loved Radian 3RXT, the Radian 3QX provides baby and infant protection, with a Safe+ Newborn baby travel high wedge and a 2-in-1 infant positioning liner for a custom fit from 4 lbs. As your child grows, the Safe+ steel rear-facing anti-rebound bar increased stability and reduces rebound rotation by up to 50%, so you can keep them rear-facing for longer! The Safe+ easy-adjust 12-position headrest offers a 22% increase in occupancy range from the Radian R series. The 3QX features 6 layers of Safe+ side impact protection without compromising the 3 across installation in most midsize vehicles for those with a busy backseat. All these great features have been combined with Safe+ engineering, with the Radian 3QX subjected to a combination of the most rigorous crash tests, including front, rear, and side impacts, and rollover tests to ensure the safest seat possible. In a range of bold colors, there is a Radian 3QX to suit every child, and for added parent convenience, the Radian 3QX cover is easily removable and machine washable.
