Booster Seats

Shop Booster Seats – Safe, Compliant Car Safety for 4 to 8 Years

At Bubs n Grubs, we stock a carefully curated range of booster seats for children aged 4 to 8 years, all compliant with Australian Safety Standards AS/NZS 1754. Whether you’re transitioning from a convertible car seat or need a reliable booster for everyday travel, our range combines safety, comfort, and trusted quality.

 

Unlike car seats for younger children, booster seats are designed to position your vehicle’s seatbelt correctly over your child’s shoulder and hips. They’re fitted using your car’s seatbelt and top tether strap—not ISOFIX. In fact, ISOFIX is not permitted for booster seat installation in Australia under current safety regulations. This is one of the most common sources of confusion among parents, and we’re here to help clear it up with expert guidance and trusted product knowledge.

 

All our high back booster seats are engineered with deep side wings for impact protection, adjustable headrests for growing children, and breathable, easy-to-clean materials. Whether you’re looking for a narrow booster seat for three-across setups or something plush for long drives, you’ll find it here from brands like Britax, InfaSecure, Mother’s Choice, and Maxi Cosi.

How to Choose the Right Booster Seat for Your Child

Booster seats play a critical role in your child’s safety once they’ve outgrown their forward-facing car seat. In Australia, children are required to use a booster seat from 4 years to at least 7 years old, or until they’re tall enough to fit an adult seatbelt correctly — typically 145cm in height.

There are two main types of booster seats:

  • Harnessed Booster Seats: Used with an inbuilt 5-point harness for younger or smaller children (ideal for ages 4–6). Great for children not yet ready to transition to a seatbelt.
  • Seatbelt-Positioning Booster Seats: Used with the vehicle’s lap-sash seatbelt, typically suitable from age 6–8. These position the belt correctly over the child’s shoulder and hips.

Key Features to Look For

  • ✔️ Deep side impact protection wings
  • ✔️ Adjustable headrest for growth
  • ✔️ Top tether strap for secure installation
  • ✔️ Breathable fabrics for comfort on longer trips
  • ✔️ Slim fit design for 3-across seating in smaller cars

Important Safety Note:

Booster seats must be secured using a seatbelt and top tether in Australia. ISOFIX is not used or approved for booster seat installation under AS/NZS 1754. Be wary of overseas content or grey imports that suggest otherwise.

Frequently Asked Questions About Booster Seats

What age can my child move to a booster seat in Australia?

In Australia, children can move to a booster seat from the age of 4, provided they’ve outgrown their forward-facing car seat with an internal harness. The booster must be used with a top tether and seatbelt, not ISOFIX.

Do booster seats use ISOFIX in Australia?

No. ISOFIX is not approved for booster seat installation under Australian Safety Standards (AS/NZS 1754). Booster seats are secured using your vehicle’s seatbelt and top tether anchor.

What is the safest booster seat for a 4-year-old?

The safest option is a harnessed booster seat with side impact protection and top tether compatibility. Look for seats rated highly under the CREP (Child Restraint Evaluation Program) and suited to your child’s height and weight.

Can I use a backless booster seat?

Backless booster seats are legal in some Australian states but are generally not recommended due to the lack of head and side protection. High-back boosters are safer and preferred for most children under 8.

How do I install a booster seat correctly?

Booster seats must be installed using the vehicle’s seatbelt and a top tether strap. Always follow the manufacturer’s guidelines, and take advantage of our half-price installation service in Brisbane to ensure correct fitment.
