Side Impact Cushion Technology (SICT™) - Head Protection 
Unique SICT layer provides 180 degree protection around a child’s head. SICT minimises the energy generated in a side impact crash. 

Rear Facing For Longer 
Your child can remain rearward facing until they are approximately 2-3 years old, which is safer for your child. 

Active Head Restraint (AHR)
Designed specifically with deeper side wings that shield and contain your child’s head in a side impact crash. AHR grows with your child working with SICT to contain your child’s head and to minimise impact forces. 

Thermo5™ Bamboo Fabric 
Thermo5 High Performance fabric with Bamboo delivers the premium comfort your baby deserves.

Hassle Free Harness 
Single handed height adjustable headrest and harness allows the seat to grow with your child without the need to remove and re-thread the harness. Reducing the risk of incorrect installation and enhancing correct harness fit. 

Infant Safety Cushion™ 
This cushion includes EVA composite material that provides support and protection for a small baby absorbing energy during a side impact crash. Specially designed ventilation holes offer breathability and comfort. 

This system retains the harness buckle in a forward position and prevents the child from sitting on the buckle when boarding.
