What Is a Booster Seat?

A booster seat is designed for children who have outgrown their forward-facing car seat but are still too small for an adult seatbelt to fit correctly on its own. A booster helps position the lap-sash belt across the stronger parts of your child’s body for safer travel.

When Does a Child Move to a Booster Seat in Australia?

In Australia, children must use a suitable child restraint until they are big enough for an adult seatbelt to fit properly. Many children move to a booster seat after outgrowing their forward-facing car seat, but the right timing depends on their height, weight and stage, not just age alone.

Types of Booster Seats

  • Harnessed booster seats: Suitable for children who still need the support of an inbuilt harness before transitioning fully to the vehicle seatbelt
  • Seatbelt-positioning booster seats: Designed to guide the lap-sash seatbelt correctly across the shoulder and hips
  • High back booster seats: A popular choice because they provide head support and side impact protection

Best Booster Seat for Different Needs

  • Best for younger children moving up a stage: High back harnessed booster seats
  • Best for everyday use: High back booster seats with adjustable headrests
  • Best for smaller cars: Narrow booster seats suited to tighter rear rows
  • Best for longer drives: Booster seats with deeper padding and breathable fabrics

What to Look for in a Booster Seat

  • High back design for better head and side support
  • Adjustable headrest so the seat can grow with your child
  • Good belt positioning across the shoulder and hips
  • Top tether compatibility for correct Australian installation
  • Slim fit design if you need to fit multiple seats across
  • Easy-clean fabrics for everyday family use

Important Booster Seat Safety Note

In Australia, booster seats must be installed using the vehicle seatbelt and top tether strap. Parents should be cautious about overseas content that refers to ISOFIX booster installation, as Australian requirements are different.

Need Help Choosing the Right Booster Seat?

The best booster seat depends on your child’s size, how they currently travel, and how your car is set up. Our team can help you compare options for everyday family driving, 3-across seating or moving up from a forward-facing car seat.

Visit our Brisbane store or shop online to find the right booster seat for your child with expert support every step of the way.
