The new KIDFIX M i-SIZE model has been developed in cooperation with leading car manufacturers to protect children aged 3.5–12 years. As a model in accordance with the latest i-Size regulations, it offers reliable safety and maximum comfort. Its narrow frame fits many cars, making it an ideal choice for the needs of a growing family.
Protection you can trust The new KIDFIX M i-SIZE is designed and approved according to the new i-Size standard, in other words it has passed the strict test requirements to protect your child more effectively. The seat has been designed together with leading car manufacturers in such a way that it protects optimally in the event of collisions. The well-padded side parts and headrest help protect the child in the event of an accident.
Comfort and practicality Comfort and practicality are key words when using the KIDFIX M i-SIZE model. The well-padded, comfortable fabric coverings and the ventilation holes in the shell placed in carefully considered places guarantee that the child will remain comfortable for a long time. Because the model of the KIDFIX M i-SIZE seat is narrow, they can be installed in the back seat of many cars three in a row. Headrest markings help parents find the right height conveniently every time.
Responsible quality - We care about the world in which our children grow up The intelligently designed KIDFIX M i-SIZE weighs about 1.3 kg less than its predecessor, and is designed and manufactured in our factory in Germany - this means shorter transport distances, so we can also minimize the environmental impact of transport. We've replaced our packaging with environmentally friendly options: you'll notice that KIDFIX M i-SIZE is packed in a plant-based bag and recycled boxes from responsible sources. Even the fasteners we use to attach product information are biodegradable, so microplastics do not enter the ecosystem.
Attaches with ISOFIX attachment This child seat must be installed in the car's three-point seat belt and ISOFIX attachment points. It guarantees a safe and strong connection between the child seat and the car, even if the child is not sitting on the seat. KIDFIX M i-SIZE includes integrated ISOFIX fasteners, which allow you to attach the car seat to your car's ISOFIX mounting points. The performance of the ISOFIX anchorage system in the event of an accident is excellent when your child is secured using the car's three-point seat belt, ensuring that the car seat is always properly secured in the car, even when your child is not using it. Check the product page of our vehicle catalog to see if the car seat is compatible with your car.
Seat belts This child seat can be secured with the car's three-point seat belt. This option is convenient if the seat is used in several cars, as not all cars may have ISOFIX attachment points. The safety belt guides included in the safety seat help to fasten the seat correctly. Check your vehicle owner's manual for the correct seat positions in your car and ask your local dealer to do a test fit on your car (ask someone trained by Britax) before buying a car seat.
