CYBEX Aton 2 Infant Car Seat offers your baby a plush, comfortable environment while making it easier for you to use them every day. Weighing in at 9 lbs., the CYBEX Aton 2 is one of the lightest carriers on the market, thanks to the careful consideration of materials as well as having the release mechanism as part of the base, not the carrier.

Integrated Sensorsafe™ Technology is provided in the form of a smart chest clip in the harness which alerts when unsafe situations arise. The alerts are provided through a vehicle receiver and the caregiver’s smartphone to ensure safety for children through a user-friendly app. The SensorSafe app also provides guidance on installation, FAQs, a direct line to customer service and more.

Additional Information:

What is Sensore Safe?
  • SensorSafe™ Technology With SensorSafe™, you'll gain instant insight into your child's well-being—even when your eyes are on the road. Built into the chest clip of CYBEX car seats, the SensorSafe clip connects to a vehicle receiver which sends alerts about your child's safety, right to the mobile app on your phone.
What is L.S.P? 
  • Linear Side-impact Protection (L.S.P.) is a feature of CYBEX car seats that absorbs impact forces of certain side-impact crashes and directs these forces into the energy-absorbing shell of the car seat and away from the child’s sensitive neck area. By extending the L.S.P. system on the side of your car seat facing the door, this feature takes the initial brunt of the force and helps keep your child safer in the event of a near side impact. 
    • *Car seats with L.S.P. extended to see a reduction in near side-impact forces on the baby by up to 25% when compared to the same car seat without L.S.P. extended.
Benefits of a Load Leg Base
  • A load leg is a structural element that is integrated into the base of a car seat. It extends down to the vehicle floor and helps to distribute the crash forces away from the child by transferring the crash energy to the vehicle’s floor. The load leg is height adjustable so it can be perfectly suited to your vehicle. 
    • The load leg stabilizes the car seat and can reduce crash forces by up to 50%.
