Hi-liner SG—Our Tallest E-Type Booster Seat!

Our Hi-Liner SG— the tallest E Type Booster Seat as at 1st September, 2015 provides extra longevity and safety.

The trim has been given a make-over with unequalled comfort for a Booster Seat.

The Hi-Liner SG includes our lifesaving SLIDEGUARD Clip which prevents your children from sliding in an event of a crash more specifically, it positions the lap-belt of your vehicle correctly over your child’s hips and thighs. There’s no other ‘Anti-Submarining’ device available on the market today that can ensure this type of safety.

What’s more to love about our new Hi-Liner SG? It’s just become comfier with additional padding and trendy new colours titled: Ink Blue, Purple Haze, Red, Pink and Grey. Other key features of the new Hi-Liner SG include:

  • One-Hand Adjust Headrest - is simple to change height to comfortably fit your child in;
  • Deep Side Wings - are EPS foam lined providing additional protection in a side impact crash;
  • Arm Rests - provide for better seat belt positioning and extra comfort for child; and
  • Removable, Machine Washable Cover - in smart sophisticated colours designed to suit all vehicles.


It doesn’t stop there! Pair your Hi-Liner SG with a Britax Safe-n-Sound Protecta PLUS harness to provide your child with additional upper torso support and safety. Without this extra torso support your child is at risk of being flung forward in a crash, which could cause serious head and/or spinal injuries. The Protecta PLUS harness which includes a frontal harness adjuster, allows parents to install the harness through slots of Harnessed Booster Seats and Expandable Booster Seats which means that the harness fits snuggly on the child’s shoulders.

Our mission and priority is your child’s safety and we do everything we can to keep this at the forefront of all we do!

Rather than refining the existing child seat technologies; we have listened, questioned and pushed boundaries to create safer products. We use this extensive knowledge to design products similar to the new Hi-Liner SG and Protecta PLUS harness and this is why Britax Safe-n-Sound understands how to protect a child in a crash better than anyone else in Australia.
