Suitable from birth to 4 years (105cm or 18kg) the Dualfix i-Size car seat will give you the peace of mind that your precious little one is safe at all times. Rearward facing up to 18kg the Dualfix has a 360 degree rotation system so simply spin round to use forward facing from 9kg if desired. It doesn’t even have to re-installed! The 360 degree rotation makes it easier on parents back and can be turned to the cars door for easier harnessing.

A 5-point safety harness not only keeps your infant in the correct position but is designed to distribute the forces of the impact across 5 points, two at the shoulders, two at the hips and one where the harness buckles between the legs. This helps to protect your child from all directions of impact. The Superior Side Impact System and Pivot Link System ensures in the event of a side impact absorbs the impact while directing the force first downward, into the vehicle seat, and then forward, more gently – greatly reducing the risk of head and neck injury.
