The Cybex Aton M SensorSafe Car Seat is made with state-of-the-art technology to keep baby safe. SensorSafe will alert you if your little one is still strapped into the back seat even when your car has been switched off. It’s designed with linear side-impact protection to absorb shock from collision. Plus, an extendable canopy with a UPF 50+ rating keeps the sun out of their face.


  • Cybex Aton M SensorSafe Car Seat features innovative technology that offers easy functionality in a safe and thoughtfully designed infant car seat. This car seat integrates important safety technology into the chest clip of the harness to alert when unsafe situations arise. The alerts are provided through a vehicle receiver and the caregiver’s smartphone to ensure safety for children in a range of unsafe situations.
  • 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 Linear Side-Impact Protection System and the energy-absorbing shell helps protect baby.
  • The Linear Side-Impact Protection (L.S.P. System) provides extra safety in the event of a side-impact collision. The L.S.P. System systematically absorbs 25% more impact forces of a side-impact collision in a linear series of reactions through the use of the shoulder and head protectors.
  • European load leg prevents the seat from rotating forward and keeps the seat at the same angle during a crash to support and protect your child. It also helps decrease crash energy by up to 50%.
  • XXL sun canopy with UPF 50+ sun protection ensure a comfortable ride. It can also be extended incrementally, offering protection from the sun and against wind.
