Cybex Base M i-Size2020

The Cybex Base M is part of the Cybex Modular System and compatible with the Cybex Infant Car Seat  and Aton M i-Size.

The easy, safe and quick installation of the base provides the highest level of comfort. The child safety seat or the infant car seat is to be attached directly to the base by clicking it in. An additional base is the ideal solution for a second car – this way, you can interchange your car seat between two cars without any effort and in no time at all.

The Cybex Base M is to be installed by using the Isofix connectors in your vehicle, which provides additional stability and safety. Furthermore, the height-adjustable support foot improves stability in case of an accident. A green indicator confirms the correct installation of the infant car seat. In order to release the infant car seat from the base, simply press the unlock key.

Please note: Only the Cybex Base is included in delivery!
