Frequently Asked Questions (FAQs)
1. What is ISOFIX on a car seat?
ISOFIX is the international standard for child car seat fittings in cars. It is a metal attachment that is built into your vehicle's seating by the car manufacturer. This attachment matches corresponding ISOFIX 'fingers' found on children's car seats designated 'ISOFIX seats'.
2. What is the difference between ISOFIX and non ISOFIX?
The difference between ISOfix and non ISOfix is the fitting system for the car seat and the car. If the car seat is non-ISOfix it would be fitted with a car seat belt, if it uses ISOfix it would be clicked onto the car's ISOfix anchorage points.
3. Do all car seats use ISOFIX?
Isofix has been standard on all new cars since the mid-2000s so if there is a high chance, your car will have it fitted. Originally Isofix had the two anchor points but some cars also have a top tether point – usually on the back of the seat.
