Meet our Maxi-Cosi RodiFix M i-Size
This forward-facing car seat is designed according to the highest safety standards and offers extra side protection – ensuring long-lasting safety for your child from 3.5 up to 12 years (100 – 150 cm)

Built to the highest i-Size safety standards and with ISOFIX connectors, this child car seat offers great stability. As 45% of impacts come from the side, the integrated G-CELL Side Impact Protection is engineered to spread the forces of a side impact away from your child, to reduce injury especially around the head, neck and shoulders.

Ease of use
With ISOFIX connectors, the car booster seat is super-quick and easy to install in the car. Once fixed in place, its child-friendly design makes it super-easy for independent children to buckle-up themselves as there are no bulky armrests getting in the way. The seat’s adjustable design follows your child’s growth too – simply press a button on the back of the headrest/backrest to adjust the height as they grow.

With its adjustable height feature, the RodiFix M i-Size keeps your little one safe, protected and comfortable as it adapts in sync with your child’s growth from 3.5 – 12 years (100 – 150 cm). Just press the button on the back of the headrest/backrest and slide up for the most comfortable fit, providing more than 8 years’ peace of mind.

The padded headrest/backrest and cushioned seat – made using 100% recycled fabrics – are not only protective, but provide extra comfort on every journey.

Practical information
You install the car seat with ISOFIX by pushing out the ISOFIX anchorages from the car seat completely and slide these into the ISOFIX connecters in the seat of your car. The base should click from both connectors, followed by an extra push against the seat. Lastly, you can install the seat belt following the belt guide system and you are ready to go!
