Child seat, ECE R129/i-Size StandardProduct details
The Kidfix M I-Size was developed in collaboration with leading car manufacturers so that children from 3.5 to 12 years can travel safely. It is approved according to the new i-Size standard and offers reliable safety and maximum comfort. The narrow seat design allows the child seat to fit in many vehicles, which is why it can be the ideal solution for the needs of your growing family.
The new Kidfix M I-Size has been developed and approved according to the new i-Size standard and meets even stricter test criteria to offer your child the best possible protection. For maximum safety in the event of a collision, the seat was developed in collaboration with leading car manufacturers. The soft, padded side wings and headrest provide additional protection for your child.
Maximum comfort and functionality are always on board with the Kidfix M I-Size. The soft, padded fabric covers and the carefully placed ventilation holes in the shell ensure that your child is always comfortable, even on longer car journeys. The slim design of the seat allows three Kidfix M I-Size seats to be fitted in the back seats of many vehicles, while handy markings help to adjust the headrest to the correct height every time.
The Kidfix M I-Size is around 1.3kg lighter than its predecessor. It is manufactured in the factory in Germany - creating more efficient transport routes and protecting the environment. For the packaging of the Kidfix M I-Size, only sustainable plant-based bags and cardboard boxes made of recycled material are used, obtained from responsible sources. This saves the environment and improves the CO2 balance. Even the labels on the products are biodegradable, so that no microplastic enters the ecosystem.
