ISOFIX stands for ‘International Standards Organisation Fix’. It allows you to fit a car seat into a vehicle easily and safely without using a seat belt.

Why choose ISOFIX?

With ISOFIX, the risk of installing a car seat incorrectly is greatly reduced. Up to 80% of car seats are fitted incorrectly. Benefits of ISOFIX car seats:

  • It provides a rigid, permanent connection between the car seat and the vehicle frame. During emergency break situation or accidents, less force will impact on your child
  • There are indicators showing you have fitted the car seat correctly
  • It is a system that has shown to be outstandingly safe in tests
  • It is easy and quick to install and remove

How does ISOFIX work?

ISOFIX car seats have two arms or connectors on the back of the seat that hook, or anchor onto small metal bars fixed to the frame of your vehicle. You will find the points where the back seat meets the seat cushion. By pushing the seat backwards onto these anchor points, the seat locks directly onto the frame of your vehicle.


Types of ISOFIX car seats

There are three approved forms of ISOFIX car seats:

  1. Universal – Uses either a top tether or foot prop, in addition to the connectors, to fix the seat to an additional anchorage point for forward-facing seats.  Universal ISOFIX car seats should fit into most new vehicles.
  2. Semi Universal – Uses a top tether, foot prop and connectors but is not compatible with all cars. Can be used with forward and rearward-facing (i.e. lie-flat) car seats.
  3. Vehicle Specific – Uses only the anchor point to secure the seat. This method is vehicle specific and is only compatible with certain vehicles.
