ECE R129 (aka i-Size) is the most recent regulation governing the safety of car seats and is a companion to the already existing regulation ECE R44.
ECE R129 was introduced in Europe in July 2013 with the objective of heightening the safety standards for children in cars and making it easier for parents to select a car seat.
Both regulations are currently in effect and apply to the transport of children in cars from birth up to about 12 years of age (0-36 kg/40-150 cm)
The orange type approval label, which must always be present on the product, identifies the regulation that was applied when the car seat was type approved.
