How do you extend car seat straps?

It’s crucial that your baby car seat is properly fitted and secured to allow your child to travel safely in your vehicle. In many cases, a standard seat belt is not enough to secure your baby seat. Our 300mm child restraint extension strap can extend your car seat strap, giving your little one the safety and protection they need.

Can you replace car seat straps?

Car seat straps can be replaced. Ensure that your car seat straps meet Australian safety requirements and regulations, and that they are compatible with both your vehicle and your baby car seat. Always follow the manufacturer’s instructions when replacing car seat straps. For more information or advice, get in touch with our friendly team.

Can you use a seat belt extender with a car seat?

Car booster seats use the vehicle’s seat belt to hold the booster seat in place. A seat belt extender cannot be used with a car seat. This is because the lap belt used to secure your child may not fit over them in the correct position, which can severely compromise their safety.
