The Liberty Onyx is a Convertible Booster Seat designed to protect children from approximately 6 months to 8 years, offering extended safety and long-lasting use through every stage. It begins as a harnessed seat with the built-in six-point harness and later converts into a Booster Seat using the vehicle lap-sash belt once your child reaches the middle height marker. Secur-air™ and Air Cocoon Technology™ (A.C.T.) work together to dramatically reduce crash energy to the head and body, helping protect your child in an accident, while the strong blow-moulded shell provides enhanced structural durability. With one of the tallest exit markers in Australia (57cm seated shoulder height), Liberty offers extended security for older, taller children.
Designed for everyday family use, Liberty Onyx includes an adjustable headrest for a perfect fit as your child grows, and Active Fabric™ Onyx covers that are cool, breathable, and machine-washable for effortless cleaning. The seat’s foldable shell allows easy storage and transport, making it a practical solution for families who need flexibility without compromise. Durable, adaptable, and built to last, Liberty Onyx is a smart and stylish choice for growing families.
