recommends the use of child seats with a backrest. Group 2 child seats are for children up to
the age of about seven, group 3 child seats for those older than seven.
Not every child will fit in the child seat specified for their weight group. Likewise, not every seat
will fit in every vehicle. Therefore it is vital to check that the child fits properly in their child seat
and that the child seat can be securely fastened in the vehicle.
Child seat approval categories
Child seats can be classified as universal, semi-universal or vehicle-specific (all in accordance
with regulation ECE-R 44), or as i-Size (in accordance with regulation ECE-R 129).
—Universal: child seats with universal approval are approved for use in all vehicles. No type list is
required. ISOFIX child seats with universal approval must be additionally secured using a strap
over the top of the vehicle seat (top tether).
—Semi-universal: semi-universal approval requires other safety devices for attaching the seat
(that require additional testing) in addition to the standard requirements for universal
approval. Child seats with semi-universal approval come with a type list. The seats should only
be used in vehicles that are included on this list.
—Vehicle-specific: child seats with vehicle specific approval must have undergone dynamic
testing in each model of vehicle for which it is approved. These child seats also come with a
type list.
—i-Size: child seats with i-Size approval must conform to the installation and safety
requirements prescribed in regulation ECE-R 129. Contact the child seat manufacturer to find
out whether child seats are approved for this vehicle, and if so which ones, in accordance with
i-Size.
