Longer 5 point harness usage

How to install your Radian 5 forward facing

The Diono Radian 5 multi-stage car seat allows for longer 5 point harness use when forward facing. Radian 5 can be used forward facing from 9kg – 25kg. Keeping children in a 5 point harness beyond standard milestones and capacity limits helps ensure maximum containment and comfort while providing complete head to hip protection.
