Why choose ISOFIX?
A car seat is only safe when it is correctly attached. That is why more and more parents are choosing ISOFIX.
Faster attached
Thanks to the fixed attachment points, you can easily secure the car seat without using the seat belt.
Less chance of errors
Research shows that car seats that are attached using the car seat belt often do not stay securely in place. ISOFIX significantly reduces this risk by connecting the car seat directly to the car’s body.
Maximum stability
Because the car seat is securely attached to the car, there is less movement during driving and the system provides optimal protection in the event of a collision.
What is ISOFIX?
ISOFIX is the international standard for safely securing car seats. Between the backrest and the seat of the rear seat are two metal attachment points that are attached directly to the car’s body. The car seat simply clicks into place here.
This significantly reduces the risk of incorrect installation and creates a stable connection between the car seat and the car.
Almost all cars produced since 2002 come standard with ISOFIX mounting points.

Frequently asked questions
Why is rearward transportation safer?
During the first phase of life, a baby’s head is relatively heavy compared to the rest of their body. The neck muscles and vertebrae are still in full development and may not be able to properly absorb the forces released in a collision.
Therefore, safety experts recommend transporting babies and young children in the rear-facing position for as long as possible. In a frontal collision, the forces are better distributed over the back, neck, and head, which significantly reduces the risk of serious injury.
The Sleeworld Mondo supports this safe way of traveling and makes it easy to transport your baby rear-facing during the recommended period.
What is the advantage of ISOFIX compared to a seat belt? Does it transport passengers more safely?
ISOFIX provides a direct connection between the car seat and the car. This reduces the risk of incorrect installation and makes the car seat more stable during driving.
Are all cars compatible with ISOFIX?
Almost all cars manufactured since 2002 come standard with ISOFIX mounting points. Always check the manual of your car to be sure that your vehicle is suitable.
What does i-Size mean?
i-Size is the latest European safety standard for car seats (R129). This includes, among other things, length, side protection and safe rearward travel.
At what age can you transport a child in the rear seat?
Safety experts advise transporting children rear-facing for as long as possible. The Sleeworld Mondo supports rear-facing travel up to the recommended length and age according to the i-Size guidelines.
