Aton M i-Size Infant Car Seat

Modular Innovation Meets Highest Safety Standards

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 (ECE R-129) is the new 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).

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.
