The chancel is a real find! In fact, it makes it easy to install your bé by completely unzipping it beforehand. It's also easy to remove your sleeping bag from the car seat by unzipping the cover. In short: a super-practical comfort bag for your baby. The chancel has openings at the back to make it easier to attach belts. This is a universal seat cover for the Maxi Cosi and any other brand of Category 0 car seat with a three- or five-point harness. You can also use this comfort bag in the pram. That way, your baby will be snugly bundled up for a walk in no time.
