Product details

The Advansafix M i-Size has been designed to ensure safe travel for children from 15 months to 12 years old. It is approved according to the new i-Size regulation, offering enhanced safety and maximum flexibility. You can rely on it. The seat can be easily converted from a 5-point harness child seat to a 3-point vehicle belt with just a few simple steps. Your little one is particularly well protected with the 5-point harness up to a weight of 21 kg.

i-Size: Safety for both small and large. In the Advansafix M i-Size, your child travels especially safely—from toddler age until they no longer need a child seat. They are optimally protected in this 3-in-1 child seat. It’s reassuring to know that the Advansafix M i-Size is approved according to the new i-Size regulation. The 5-point harness can be used for children up to 21 kg, providing even more safety for your child.

Flexibility at your fingertips: Thanks to the Flip & Grow function, you can easily switch between the integrated 5-point harness and the 3-point vehicle belt as your child grows. And since nothing needs to be removed from the seat, you can also switch back to the 5-point harness at any time. With the EasyRecline function, you can adjust the built-in seat to various comfortable resting positions—without having to readjust the Top Tether. Just the way that is most comfortable for your child.
