360 Degrees peace of mind

Meet Marie, the newest member of the Swandoo family. Named after scientist and double Nobel Prize winner Marie Curie, this seat offers a simple and intuitive user experience while surpassing safety standards. Just like other Swandoo products, it was developed by parents, for parents – and it shows!


360° Rotating i-Size Child Seat

Marie has a unique 360° rotation, enabling you to comfortably face your child when placing in, or out of the seat.

But there‘s more! Thanks to the integrated Child Direction Assistance, kids under the height of 76 cm, can’t be placed into a forward facing position. This helps you follow the 15 months rear facing requirement and keeps your little one safer.

  • Suitable for babies and child to approx. 4 years of age, to 18 kg./105 cm
  • Meets ECE R129 i-Size (phase 3) safety standards.
  • Designed in Vienna with love from Swandoo’s passionate design team


Perfect recline system

Marie allows 4 reclining positions, both rearfacing and forward facing, to make sure a child is transported in the best possible conditions, at each stage of its development.

Orbital rotation

Spin from any of the four recline positions.

Memory foam headrest

Marie’s headrest is made with memory foam to provide additional side and front impact absorption and comfort.

Better support

The newborn pillow helps achieve a better fit and offers extra protection for babies up to 3 months.

Enhanced Side Protection

The Side Impact Buddy (accessory) can simply be attached on the window side of the seat for extra protection. Plus the unique shell structure and premium materials offer extra side-impact protection.

Enhanced Shell Protection

With its unique shell structure and premium quality materials, Marie offers superior comfort and safety. The unique shell absorbs impact energy instantaneously and gently guides it away.
The very robust and durable EPP material, which is also increasingly used in sports products that have to withstand potential impact forces, is extremely energy absorbent and is less prone to perish over time. In combination with the shell it merges into a perfect safety symbiosis.

Remarkable airflow

Marie offers exceptional seat ventilation. Your child’s comfort is vital to us so we have designed Marie to provide a relaxed and comfortable travelling experience for them (and you of course).
The shell structure has an integrated ventilation system which guarantees a constant airflow and the incorporated EPP (Expandable Polypropylene) also supports a safe and comfortable body temperature. You can see the ventilation from the back of the seat and behind the child’s back looking inside the seat.

A simple visual guide for a correct child fit, improving safety and comfort.

Harness holders

Padded shoulder pads with antislip material for extra comfort and safety.
