Verified safety for relaxed journeys

The Aton S2 i-Size and Base One are developed and approved to the latest safety standards R129/03, including i-Size compatibility and enhanced side-impact testing.

Reduces impact forces in the event of a side collision

The Linear Side-impact Protection System, which can be folded out on the door side, transfers up to 25% of the forces of a side impact into the energy-absorbing shell, helping to ensure maximum safety on the road.

Grows with your baby

Because of its 11-position height-adjustable headrest, the infant car seat grows with your child up to the age of 24 months. Head, neck and shoulders remain ergonomically supported at every stage, while the harness automatically adjusts to each growth phase.

Protects your child from the sun and wind

The integrated, foldable XXL sun canopy reliably shields against the sun’s rays and is equipped with UPF50+ fabric to protect your baby's sensitive skin. Outside the car, the canopy also protects from the wind.

Simple and easy handling

Weighing only 4.2 kg, the Aton S2 i-Size is easy to carry and position in the car or on the stroller. This reduces the strain on your back and allows you to carry your baby effortlessly even in their second year.

Continue your journey outside the car

The Aton S2 i-Size can be easily attached to any CYBEX or gb stroller or buggy. The transition from riding in the car to a walk in the city is simple and smooth.

Ergonomic comfort for small babies

The perfect fit from day one. The newborn inlay gives babies up to a size of 60 cm the ergonomic support they need. When your baby grows bigger, the inlay can easily be removed. So you can be sure that your baby is enjoying optimal comfort from day one.
