The ADVANSAFIX IV M grows with your child - from 9 to 36 kg. Numerous functions such as EasyRecline offer additional comfort for both small and large children. Thanks to the FLIP&GROW function, you can switch between the integrated 5-point harness and the 3-point vehicle harness in a few simple steps as your child grows. This is not only comfortable for children, but also for parents.
Flexibility that grows with you
With the ADVANSAFIX IV M the seat now grows even more comfortably with your child. Thanks to the FLIP&GROW function you can switch from the integrated belt system to the 3-point vehicle belt in just three easy steps when your child reaches 15 or 18 kg. Nothing has to be removed from the seat, so nothing can get lost and can be changed again at any time. The soft padding and EasyRecline with three adjustable seat positions - for young and old - ensure that your child is comfortable on every ride.
Simply safe - every day
The safety of your child is very important to us. That is why ADVANSAFIX IV M ensures that your child is always well protected. When you fasten your child with the 3-point vehicle harness, the SecureGuard keeps the lap belt in an optimum position over the pelvic bones, thus reducing the risk of abdominal injuries. In addition, the deep, softly padded side bolsters and the v-shaped headrest minimize the risk of injury to your child in a side impact.
Britax Römer Pivot Link System
In the event of an accident, our patented Pivot Link ISOFIX system reduces the forward movement of the child seat and directs the forces mainly downwards. 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 child 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 an impact to 5 points and reduces them: at the shoulders, the hips and at the buckle between the legs. This way your child is protected from all sides in an accident.
Soft neoprene special shoulder pads
The soft neoprene special shoulder pads nestle pleasantly 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 harness 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 belt for adults. By optimally positioning the lap belt over your child's pelvic bones, the SecureGuard reduces the forces exerted in a frontal impact by up to 35%* while allowing your child to move freely while driving.
*Internal Britax 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.
Our V-shaped headrest is specially designed to keep the movement of the child's sensitive head in control in the event of a side impact. This not only provides optimum protection but also a great deal of comfort. You can also easily adjust the headrest and harness system from the front of the seat, so that both fit your child's size perfectly.
In the event of a collision, the Top Tether reduces the rotation of the child seat, thus reducing possible injuries to the head and neck area. 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 put the seat in three comfortable sitting positions. Even while your child is sitting in the seat and without readjusting the Top Tether - very comfortable for child and parents.
If your child has reached a minimum of 15 kg and a maximum of 18 kg, you must change 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 chaotic on the street. A drink can easily be spilled 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.

Refer to your car manual for the mounting points for ISOFIX and Top Tether in your car.
