The Diono Radian 3RXT Special Edition is the original slim-fit 3 across all-in-one convertible car seat to protect your child from baby to booster seat. Lovingly finished with exclusive contemporary fabrics, the car safety seat is engineered with a steel-reinforced frame for 10 years of use. The convertible car seat provides safe and comfortable baby positioning thanks to the 2-in-1 infant liner with integrated newborn baby travel high wedge which helps reduce head slump to keep airways open. As your baby grows, simply remove the wedge to allow the liner to give extra comfort and support. Designed and engineered with complete rear-facing protection, this car seat is suitable for up to 50 pounds. Transition from rear-facing to forward-facing using the adjustable, 12-position headrest and rest easy knowing the SuperLATCH system is super easy to install. The slim-fit design will fit 3 across most vehicles without compromising child safety or passenger comfort and the steel-reinforced cup holder stores essential road trip drinks and snacks. The Radian is also aircraft certified (FAA approved), so you can take safety with you wherever you go. Have the peace of mind you deserve when you travel with the Diono Radian 3RXT Car Seat.
