Products description

The ADVANSAFIX M i-SIZE is designed to help children from 15 months to 12 years travel safely. It is approved according to the new i-Size regulation and offers even more safety and maximum flexibility. You can rely on it! The seat can be converted from a child seat with a 5-point belt to a 3-point vehicle belt in just a few simple steps. Your little one weighing up to 21 kg is particularly well protected with the 5-point harness.

i-Size: Safety for big and small
With ADVANSAFIX M i-SIZE, your child will ride particularly safely - from infancy to the point when they no longer need a child seat. Because it is optimally protected in its 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. And the 5-point harness can be used for children up to 21 kg. That means even more safety for your child.

Flexibility at your fingertips
Thanks to the FLIP&GROW function, you can easily switch between integrated 5-point harness and 3-point vehicle harness as your child grows. And because nothing has to be removed from the seat, you can switch back to the 5-point harness at any time. Thanks to the EasyRecline function, you can move the built-in seat to different, comfortable resting positions - without having to readjust the Top Tether. Whatever is most comfortable for your child.

Quality - Made in Germany
To guarantee the highest possible quality, Britax Römer not only has the entire product development process under one roof, right up to the finished child seat, but the finished products are also regularly tested on the company's own state-of-the-art crash test facility.

Product properties

Britax Römer Pivot Link System

In the event of an accident, our patented Pivot Link ISOFIX system reduces the forward movement (2) of the child seat and directs the forces mainly downwards (1). This means that the force of the impact is cushioned by the car seat cushion and the risk of head and neck injuries is significantly reduced.

5-point belt system

We are convinced that a 5-point harness system is the best way to protect your child in a car seat. Because it optimally secures your offspring in the protective shell of the seat. In the event of a collision, the belt system distributes the forces that act in the event of a collision to 5 points and reduces them: at the shoulders, hips and the buckle between the legs. Your child is thus protected from all sides in an accident.

Soft neoprene special shoulder pads

Our soft neoprene special shoulder pads snuggle comfortably to your child's body. In the event of an impact, they not only reduce the forward displacement of your child - they also make the 5-point harness even more comfortable. You can also easily remove them for washing without having to intervene in the belt system.


The SecureGuard helps to provide extra protection for your child's sensitive abdominal area - thanks to an additional 4th attachment point of the 3-point car seat belt for adults. By optimally positioning the lap belt over your child's pelvic bones, SecureGuard reduces the forces exerted in a frontal impact by up to 35%* while allowing your child sufficient freedom of movement while driving.
*Britax internal tests with a Q6 dummy that is the same size and weight as an average 6-year-old child.

Protection thanks to high backrest

Child seats with backrests protect your child in three ways: the seat shell protects your child from head to hip, especially in the event of a side impact. At the same time, the upper and lower belt guides ensure that the vehicle belt is in the right place and the padded headrest provides safety and comfort for your child's head and neck.

V-shaped headrest

Our V-shaped headrest is specially designed to keep the movement of the sensitive child's head controlled in the event of a side impact. This not only provides optimum protection but also a great deal of comfort. In addition, you can easily adjust the headrest and harness system from the front of the seat, so that both fit your child's size perfectly.

Top Tether

In the event of a collision, the Top Tether reduces the rotation of the child seat, thus reducing potential head and neck injuries. Thanks to the double anchorage points, our v-shaped Top Tether offers even more stability and safety for your child than conventional Tether systems.

EasyRecline is suitable for all age groups and allows you to adjust the seat to different comfortable sitting positions. Even while your child is sitting in the seat and without readjusting the Top Tether - very comfortable for child and parents

When your child has reached a minimum weight of 15 kg and a maximum weight of 21 kg, you must switch from the integrated 5-point belt to the 3-point vehicle belt to secure your child in the child seat. Thanks to the FLIP&GROW function, this is now possible in a few simple steps. Simply adjust the headrest and stow the harness in the backrest so that it does not get lost. Then adjust the FLIP&GROW conversion plate with the SecureGuard and you are ready to go.

Quickly removable cover

Sometimes things get pretty messy on the street. It's easy to spill a drink or your child might get sick from driving. With wise foresight, Britax Römer has developed a machine-washable seat cover that can be easily removed without removing the seatbelt. So you can quickly get the seat clean again - and you can get on with your journey.
