Marie 3 360° Rotating i-Size Child Seat


Meet Marie, our rotating car seat for the little and not-so-little ones. Named after the scientist and double Nobel Prize winner, Marie Curie, this seat offers a simple and intuitive user experience while surpassing safety standards. Winner of the renowned iF Design Award 2020, Marie is now available in its third generation, combining a series of smart product features with small, but important quality improvements.

Marie 3 was crowned ‘Best in Category’ (approved up to approx. 4 years/ 40-105cm) at the Autumn 2021 consumer tests by ADAC, ÖAMTC and TCS and achieved a remarkable five star safety rating in rear-facing position.

We pay attention to even the tiniest of details and continuously work on enhancing the safety, usability, quality, and comfort of our car seats. Because, as parents, we know that small things can make a big difference – just like our children!





Thanks to its unique orbital rotation, Marie enables you to comfortably face your child when boarding, or leaving the seat.

In addition, the integrated Child Direction Assistance ensures that parents follow the 15-months rear-facing requirement. Simply put, Marie keeps the little ones even safer and helps avoid misuse by not allowing children under 76 cm to be placed into a forward-facing position. We recommend keeping your child rear-facing for as long as possible – ideally until ~4 years (105 cm).



Statistics show around 50% of children have a loose-fitting harness or belt when travelling in a car seat. This significantly reduces the safety of the child and can lead to serious injury in case of an accident.

In our mission to fight misuse and ensure the highest safety standards, we developed the Harness+ to help you adjust the harness correctly when placing your precious cargo. With Marie you really can’t go wrong!
