Booster Seat (Child Booster)

A booster seat raises an older child so that the car’s adult seatbelt fits correctly across the shoulder and hips.

What is Booster Seat (Child Booster)?

High-back boosters also give side and head protection. Booster cushions without a back give little side protection. Many have ISOFIX connectors for stability. Approved seats carry an ECE R44 or R129 label; R129 is the newer standard.

How it works

The child sits higher, and guides route the belt over the shoulder and low across the hips.

Why it matters for your car

Use the booster until the child is tall enough for the belt to fit; local rules set the limits. Never route the belt under the arm or behind the back.
