Koos iSize

Maximum convenience with a single click

The new Koos iSize no longer uses the vehicle seat belts as an anchoring system. To comply with the strict ECE R129 i-Size European safety standard, Koos iSize uses a base with ultra-quick connectors with Pro-fi x locking from Jané and anchored to the car with isofix and the front leg for complete safety and reliability.
