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.
Need help choosing the safest option for your vehicle and child? Visit us in Brisbane or shop online with confidence — and take advantage of our half-price car seat installation service with every booster seat purchase.
Your child’s safety is our top priority — and it’s our mission to make it easy for parents to make the right choice, every time.

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.
