What is ISOFIX?

ISOFIX is an international standard for safely and easily attaching an infant car seat in vehicles without using the vehicle’s seat belts. Using ISOFIX connectors dramatically reduces installation errors and improves the safety of car seats.

The name ISOFIX comes from the merge between ISO (International Standardization Organization) and FIX (Fixation). The ISOFIX standard warrants two main safety elements:

  • Rigid ISOFIX connectors on the car seat base which connect to standard anchor points in the vehicle seat.
  • Reinforced adjustable support leg (also called foot-prop).

Some cars made prior to 2006, and all cars made from 2006 are equipped with ISOFIX anchor points.

What is Semi-universal approval

Semi-universal approval is when, in addition to the standard requirements, it requires the use of an additional safety or anti-rotation device-foot prop, which may affect compatibility with certain vehicles. It also requires additional testing.

Check if your vehicle appears on the Car Fitting List for that particular child seat.

Car Fitting List

Check our car fitting list to verify that the Doona ISOFIX Base fits your vehicle. Simple Parenting recommends trying the Doona in your car first at the retailer before purchasing.

Note: The Car Fitting List is based on information received from the different car manufacturers pertaining to certain dimensions in the different models. The list cannot be considered 100% accurate as there are slight variations between different models of the same cars, and between same models in different countries. The only way to assure that the Isofix fits your car is to verify this at the time of purchase by installing the base in the car.


Our ISOFIX Base offers secure one-click installation. Once the Base is secured to the ISOFIX anchors in the vehicle, coming and going is a breeze! Simply click the Doona Infant Car Seat onto the base and the color indicator will let you know that the seat is secured. When its time to exit the car, simply release and you are on your way! Safe. Simple. Mobile.
