Modular Innovation Meets Highest Safety Standards

Together with the Base M and the Sirona M2 i-Size the Aton M offers innovative functionality and thought-out design that grows with your child: in the M-Line Modular System. This system offers two seats that fit onto the Base M so your child rides safely, comfortably and rear-facing for longer. The Aton M can also be used as a travel system with the CYBEX and gb strollers and with those of other well-known producers.

The Aton M 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.

Is this the right seat for my car?

Especially the length of the vehicle belts or ISOFIX (US: LATCH) anchorage points may vary, even during a production run of a car manufacturer.
