ISOFIX stands for 'International Standards Organisation Fix', a standard which makes fitting a child car seat quick, simple and safe. The ISOFIX system uses latches on the back of the child car seat which attach to fixed anchorage points in the car, effectively creating a rigid link between the two. The benefit of ISOFIX is that it's easier for parents to be confident they have the correct fit, than when they use a three point adult seat belt to secure a car seat. ISOFIX helps ensure the best possible protection in the event of an accident.
