Brand Story

Everyone at Maxi-Cosi has one wish in common – to understand what it’s like to be a parent today.

Many of us are parents too; we’ve done the sleepless nights and the first tooth. And we understand that when you’re facing another parenting challenge your baby will look you in the eye and chuckle, or hiccup, or give you a flower, or do something else that stops you completely in your tracks. Suddenly, you appreciate the absolute joy that comes with being a mum or dad.

We want to maximize that joy so you can get on with enjoying these precious moments. We want you to have the safest car seat that simply clicks into place and a stroller that you can always rely on. Knowing what doesn’t work helps us develop solutions that do.
