The Maxi-Cosi Kore i-Size is so easy to use, your child can buckle up by themselves! Making everyday travel a little less complicated.


The Kore i-Size can be installed with ISOFIX connectors and/ or your own car seat belt. Most cars manufactured nowadays have ISOFIX connectors making installation for this car seat a breeze. Did you know that the ISOFIX connection makes the child seat more stable? Also when your child is not sitting in the child seat, it is more stable. If your car model does not have ISOFIX connectors, you can still use the Kore i-Size with the seat belt installation method. For both installation methods please refer to your car seat manual.


At Maxi-Cosi, your little one's safety is our highest priority. From infant carriers for newborn babies to booster car seats for 12-year-olds, we are here to help carry families happily into their future. Because we care about giving you as a parent the safest car seat, we have designed our Maxi-Cosi Kore i-Size to comply with the highest and latest i-Size safety standards.
Our easy-to-use Kore i-Size car seat is designed with a Side Protection System Plus to ensure superior side protection in case there's a harmful side collision. Maxi-Cosi Kore i-Size's SPS Plus (Side Protection System Plus) reduces the risk of an injury by absorbing it the force of an impact. In addition to a regular SPS, an SPS Plus has improved impact-absorbing material added to each side wing. Combined with glass fibre shock absorbers, it offers your child maximum safety. The cocoon shell provides full-body protection on the side.

It's in their hands

Maxi-Cosi Kore i-Size is designed to make it easy for your little one to easily get in their car seat and buckle up on their own. The open space at the bottom of the car seat provides easy access to the buckle, so your child can grab the seat belt and safely insert without any hassle. It's all in their hands!

Once the ISOFIX connectors are attached to the seat of your car, the Kore i-Size backrest inclines to fit the seat of your car for a comfortable position. The car seat continues to be comfortable for many years because it grows with your child. The backrest adjusts in height and width, adapting to your child's growth up until they reach 12 years of age!
Removable cover

On the road, snacks or drinks may not always end up where they are supposed to. In case there's a little accident, we've got you covered! Maxi-Cosi's car seat cover is removable and can easily be washed in the washing machine.
