Nuna ROYL Combination Car Seat
The Nuna ROYL Combination Car Seat is designed to grow with your child from forward-facing harness mode into a high-back belt-positioning booster. Built for children from approximately preschool age through the pre-teen years, it combines long-term usability, premium comfort and straightforward installation in one streamlined seat.
The ROYL features Nuna's True Tension™ installation system, an all-steel frame, reinforced belt path and Aeroflex™ Side Impact Protection pods to help provide a secure, stable fit. With eight headrest positions, four recline positions and a no-rethread harness, it adapts easily as your child grows.
