Air flow & ventilation

The innovative design of the Avionaut AeroFIX car seat is equipped with ventilation ducts that create a unique Air Circulation System responsible for the correct ventilation inside of the car seat. This system prevents the child from sweating even during high temperatures in the car.


The seat complies with I-Size regulation. The high safety class is ensured by the optimal combination of EPP, PP, PA and memory foam that adapts and absorbs forces in the event of a collision. In addition, safety is enhanced by adjustable five-point belt harness and an adjustable large headrest that can be adapted to the needs of a growing child.


It is an innovative material which looks like styrofoam, but differs from it significantly in that it is not as stiff or fragile. In addition, it features high resistance to physical and chemical factors. Its excellent strength makes this material ideal for the construction of car seats because it does not deform, even at high impact loads from a collision. In addition, EPP is an eco-friendly material which is 100% recyclable and features anti-bacterial and fungistatic properties.

IQ isofix base

The IQ base is a reliable ISOFIX base developed for AVIONAUT Pixel as well as for AeroFIX RWF and AeroFIX. It uses a patented single socket solution for directly connecting the child seat to the car. The reduced number of connections between the belts and the ISOFIX system maximizes the child's safety by making it easier to transfer more energy to the car's structure instead of the child. Moreover, thanks to the sound signalling for correct connection to the IQ ISOFIX base of the Click n’ Drive control unit, there is no risk of the seat being wrongly fastened to the base, which maximizes its effectiveness.



Standing for International Organization for Standardisation, this is a system of fastening children’s seats to car seats. The ISOFIX system consists of two fixtures which are located between the seat and the back of the car seat. Importantly, these fixtures are attached directly to the structure of the vehicle, providing stiffer fastening than a seat belt, as well as better energy absorption. The use of the ISOFIX snap system prevents incorrect installation.
