What is i-Size?

i-Size is a new European-wide standard designed to increase the safety of child car seats.

When was it introduced?

i-Size was introduced in Europe in July 2013 and is running alongside the current regulation R44.04.

My car seat conforms to the previous regulation R44.04. Must I upgrade to i-Size?

No, i-Size does not replace the current regulation at this time. It provides an alternative option that has been tested to higher safety levels, although by 2018 we expect that all new car seats will have to conform to the requirements of the i-Size regulation. Existing R44.04 seats, however, are still legal and may continue to be used for several years.

What are the main differences between i-Size and R44.04?

i-Size requires by law that children remain rear facing until 15mths of age, irrespective of their weight. The new standard also helps parents to choose the right seat more easily by classifying car seats by the child’s length rather than weight, (please note weight restrictions on different i-Size seats will still apply).

i-Size seats have a greater side-impact standard that gives your child better protection if hit side-on. The new tests also use more technologically advanced dummies, known as the Q-series, which behave far more like real people in a crash scenario.


Current developments in i-Size

Phase 2: From 100cm – 135cm high-back booster seats to be introduced approx. 2016/2017 and includes ISOfix and none-ISOfix seats.

Phase 3: From birth to 105cm for products secured using the seat belt.
