What does
i-Size mean for
FAIRGO child seats?

All Fairgo child seats are developed in accordance with highest safety standards. Our long-time experience and good results from EuroNCAP tests showed us that enhanced fulfilment of ECE R129 is essential for a maximum child safety in modern i-Size vehicles.

Our philosophy is to provide the highest quality products to our customers, going far beyond the legal standards for purity and cleanliness. From rigorous testing at Technopark´s Impact Lab multiple stages during Research & Development, car seats manufacturing and conformity of production, to the strict ISO quality control standards we set for every partner we work with.

Easy installation

Fairgo i-Size car seats are to be installed in vehicles with the Isofix system which facilitates correct and safe installation. Every i-Size car seat fits perfectly every i-Size car.


The specification in body size (in centimetres) simplifies the choosing of the right i-Size car seat and guarantees an exact fit.

Improved safety

All i-Size approved car seats must be able to proof a side-impact test to guarantee additional safety.

New dummy generation

The new Q series of dummies enables an even more detailed analysis of crash-relevant data which contributes to the improvement of safety and the child’s protection in a crucial manner.

Protective rear-facing

For better protection of the child’s head and neck, rearward-facing transport is mandatory up to a minimum of 15 months when using an i-Size car seat.

The new standard for car seats, ECE Regulation 129 known as  i-Size doesn’t replace the more familiar Regulation 44 (R44) but runs alongside it.

I-SIZE Seats can be used up to the maximum stature
(natural standing height) of the child, specified by the seat manufacturer.

for i-Size:

  • Rear facing may be applied to any age of child.
  • Restraints for children up to 15 months must be rear facing.
  • Restraints for children up to 15 months must accommodate at least a child with a stature of 83cm.
  • Forward-facing seats mustn’t be designed to accommodate a stature below 71cm.
  • A convertible seat in rear-facing configuration must accommodate children up to at least 83cm in height.
  • i-Size seats can only be attached using ISOFIX anchorage points – there’s no option to install i-Size restraints using adult belts.


  • You’re more likely to know your child’s height than their weight so it should be easier to tell if a seat is suitable.
  • i-Size seats keeps your children rear-facing for longer – rear facing is safer.
  • i-Size approval includes a side impact test so seats should offer better all-round protection.
  • ISOFIX should make fitting easier compared to seats fitted using adult belts.


i-Size child seats can be used in any ‘i-Size approved’ seating position and must be installed according to the car manufacturer’s instructions.

Check your vehicle handbook first to see if any seating positions are ‘i-Size approved’ (not available in cars registered before July 2013)


If your car doesn’t have any i-Size approved seating positions, you may still be able to use an i-Size child restraint on seats with ISOFIX anchorage points. This is only if the vehicle and seating position are included in a vehicle-specific application list, supplied by the child restraint manufacturer.

If you plan to use your child seat in more than one vehicle it’s important to check that all have i-Size approved seating positions or appear on a vehicle specific application list.
