A 4-year-old boy attends for a preschool health check. His parents want to move him into the booster seat his 7-year-old sister has outgrown, because he says his harness is uncomfortable and his cousins of the same age all use boosters. He weighs 17 kg and is 104 cm tall. His shoulders sit two centimetres below the upper shoulder-height marker of his current forward-facing restraint, which meets the Australian Standard and is correctly installed. The family car has two rows of seats. Which one of the following restraints should he now travel in?
