- From baby’s first journey the Radian® 3RXT® SafePlus™ provides complete rear-facing protection with a SafePlus™ newborn travel high wedge
- SafePlus™ 2-in-1 infant positioning liner for a custom fit from 4 lb.
- As your child grows the SafePlus™ steel anti-rebound bar increases stability and reduces rebound rotation by up to 50%, so you can keep them in a safe rear-facing convertible car seat for longer (up to 50 lb).
- As both a rear and forward-facing convertible car seat, the Radian® 3RXT® SafePlus™ protects as they grow, with SafePlus™ easy adjust 12 position headrest that offers a 22% increase in occupancy range from the Radian® 3RXT®.
As they grow the Radian® 3RXT® SafePlus™ provides 6 layers of SafePlus™ Side Impact Protection without compromising the famous Radian® 3-across slim fit in most midsize vehicles.
All these great features have been combined with SafePlus™ engineering, with the Radian® 3RXT® SafePlus™ All-in-One Convertible Car Seat subjected to a combination of the most rigorous crash tests 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.
