Glossary
i-Size
The car seat meets the requirements of the European safety standard i-Size (ECE R129). Within the framework of this standard, it is assumed that child car seats are classified according to the height and age of the child, and not by weight (as was previously the case). It is also mandatory to fasten the retaining device using the Isofix system (see “Isofix fastening”). In accordance with i-Size requirements, car seats must be installed rear-facing until the child is 15 months old or reaches a height of 105 cm. All i-Size certified car seats must pass a side impact test. Chairs and cars that meet the requirements of the standard are marked i-Size, which confirms their full compatibility.
