Modular innovation meets the highest safety standards in the Cybex Aton M Infant Car Seat. Designed with your baby’s safety as the number one priority, it’s energy-absorbing shell combined with the Linear Side-Impact Protection integration provides ultimate protection while they’re in the car. It features a large sun canopy, a height-adjustable headrest and softly padded harness for their comfort. This infant car seat is compatible with the Cybex and gb strollers (each sold separately) so making the switch from the car to the stroller is effortless.


  • M-Line Modular System offers car seat that fits onto the Base M so your child rides safely, comfortably and rear-facing for longer.
  • 11-position height-adjustable headrest with integrated harness guides.
  • Removable seat insert. 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 Linear Side-Impact Protection (L.S.P. System) provides extra safety in the event of a side-impact collision. The Linear Side-Impact Protection System (L.S.P. System) systematically absorbs the force of a side-impact collision in a linear series of reactions through the use of the shoulder and head protectors.
  • XXL sun canopy with UPF 50+ sun protection ensure a comfortable ride. It can also be extended incrementally, offering not only perfect sun protection, but also protection against wind.


  • Anti-rebound design provides additional protection in the event of a crash by limiting the car seat's movement towards the back of the vehicle.
  • Highly visible indicators change from red to green when the car seat is locked into the base and the load leg is properly installed for extra safety.
  • Height-adjustable load leg helps reduce crash energy by redirecting forces to the vehicle floor and away from your baby.
  • Unique belt tensioning system offers quick, simple and secure installation when using either LATCH or vehicle seat belts.
  • The Aton M can also be used as a travel system with the CYBEX and gb strollers (sold separately) and with those of other well-known producers.
  • Recommended from birth up to 18 months old or up to 28.5 pounds.
  • Made in Germany.
