This car seat enables your child to stay rear-facing, with a 5 point harness, up to 25kg keeping them in the safest travelling position for longer. When your child is ready to turn forward facing they remain in a 5 point harness using the SuperGrip energy-absorbing harness pads which reduce the impact of crash forces.

With extended weight capacity, Radian 5 is the only car seat which can face both ways and take a newborn baby as well as on older child in a 5 point harness up to 25kg.

The unique steel frame means Radian 5 is super strong to resist crash forces and offer the most amount of protection. Radian 5 combines a full steel alloy frame to create the strongest car seat available with V3 energy reduction system to provide ultimate protection in all collision situations.

Straight sides ensure little ones are contained within the seat and EPP foam absorbs the maximum amount of forces to provide ultimate side impact protection. Radian 5 provides complete head to hip protection.

With memory foam seat padding and a longer seat base, Radian 5 provides ultimate comfort on all journeys. The seat encompasses super soft fabrics along with an infant cushion and head rest for extra comfort.
