When used as a Group 1 (9-18kg) car seat, the child is secured in with use of the in-built harness. When your child grows too big to be contained safely / comfortably (in the harness), it can be removed and replaced by the vehicle’s standard adult 3 point safety belt. The ergonomic adjuster makes it simple to regulate both the height of the safety belts and the headrest at the same time, ensuring safety and comfort as your child grows. Extra safety is provided in case of impact thanks to the special side protection and reinforced padding in the lumbar zone.
