At the beginning of your parenting journey, rear facing beats forward facing. Before you know it, forward is the way to go. The UPPAbaby KNOX convertible car seat easily adapts as your child’s positioning needs change.

KNOX is the first convertible car seat from UPPAbaby. A natural extension in the category after the success of the MESA infant car seat. KNOX's SMARTSecure System, similar to the MESA, provides visual indication that turns from red to green, telling parents and caregivers when the car seat is correctly installed. With clearly marked belt paths and robust lock-offs it enable parents to simply route the belts through appropriate channels then tension belt through lock-off to establish a secure installation. While the Universal Tether used in rear-facing mode reduces rotation of the seat and stress on the child's head and neck in both frontal and rear impacts.
