The Britax Römer KIDFIX M i-SIZE is a forward-facing high-back booster for children from 100-150 cm. The matching manual requires a vehicle seat with an approved three-point belt and directs caregivers to check that the car’s seating position is compatible.

The child is secured with the vehicle belt; route it through the guides as shown in the manual and check the lap section lies across the pelvis. ISOFIX may be used only as described for the exact vehicle and seat. This is a later-stage seat, not a harnessed option for a younger child.
