When designing the Advansafix IV, the aim was to create a product for the 1 / 2 / 3 market which combines a high level of safety, comfort and durability with an elegant appearance. Initially, the seat is used with a five-point harness. A later conversion to the 2 / 3 group child seat, thanks to the Flip&Grow function, is possible with just few hand movements. The integrated harness is stored behind the cover of the backrest and the shoulder pads are folded out. The side wings add strength to the side impact protection.
