With its slim design, the KIDFIX i-Size allows up to three seats to fit in the back row of various car models, while clearly marked headrest guides make it easy for parents to adjust the headrest to the correct height every time.

Comfort and practicality are key features of the KIDFIX i-Size. Its soft, generously padded fabric covers and thoughtfully positioned air vents provide a comfortable travel experience for your child.
