Aton M i-Size Infant Car Seat

The Aton M i-Size offers the latest safety technology available. When installed with the Base M (additionally available), the infant car seat complies with the new i-Size regulation. i-Size (UN R129) is the EU standard for child safety, making rear-facing travel mandatory until your child reaches 15 months. The Aton M i-Size is suitable for newborns and babies at a height of 45 cm to 87 cm (max. 13 kg).

Modular innovation meets safety standards

The Aton M i-Size offers a removable seat insert that ensures a near-flat lying position for premature and newborn babies. Together with the L.S.P. System and the energy absorbing shell the elaborate safety concept helps protect the baby. The height-adjustable head rest, a softly padded harness and the XXL sun canopy ensure a comfortable ride.

Once attached to the harness system of your car seat, the SensorSafe 4-in-1 Kit connects to your smartphone and provides essential alerts to help prevent critical situations: when your child unbuckles the clip, if your child is put at risk of vehicular heatstroke because of ambient temperature changes or from being left alone in the car, and if your child has been seated for too long.
