ADVANSAFIX M i-SIZE is designed to protect children from 15 months, right up to the age of 12 years. Approved to the new i-Size regulation, it offers safety you can trust, and maximum flexibility. The seat converts from a harnessed seat to a highback booster seat, with just a few simple steps. Children can benefit from 5-point harness protection up until they reach 21 kg.
Flexibility at your fingertips
Thanks to the FLIP&GROW function, you can easily change from the integrated 5-point harness to the car’s 3-point seat belt as your child moves to the next stage. And because no parts have to be removed from the seat when changing stages, the seat can also be converted back at any time. With the EasyRecline function, you can recline the seat to your child's comfort without readjusting the installation.
Quality – Made in Germany
To guarantee the highest quality possible, we keep the whole product development process under one roof, from the initial idea right up to the finished product. Plus, our car seats are regularly tested in our in-house, state-of-the-art crash test facility at Britax Römer Germany.
We believe a 5-point harness is the safest way to secure your child in a car seat because it keeps your child safe and tight in the seat’s protective shell. In the event of a collision, the harness distributes 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.
Soft neoprene performance chest pads
Our new, soft neoprene performance chest pads fit comfortably on your child’s chest. They help reduce your child’s movement in the event of a collision, and add even greater comfort to the 5-point harness. Plus, they can be easily removed for washing without disturbing the harness.
The SecureGuard helps to protect your child’s delicate abdominal area by adding an extra – a 4th – contact point to the 3-point seat belt. By keeping the lap belt in an optimal position over your child’s pelvic bones SecureGuard helps reduce abdominal forces in the event of a frontal collision by up to 35 %*, and at the same time allows your child freedom of movement during the journey.
Our highback boosters protect your child in 3 ways: the seat shell provides head to hip protection for your child, especially in the event of a side impact; the upper and lower belt guides provide correct positioning of the seat belt; and the padded headrest provides safety and comfort for your child’s head and neck.
Specially designed to control the movement of your child’s head, our V-shaped headrest ensures optimal protection in the event of a side collision while providing ultimate comfort at the same time. Plus, the headrest and harness can easily be adjusted from the front of the seat to suit your child’s height.
