The new Cybex Sirona M is the only car seat that keeps your child safe not only with its crash-protection features, but with innovative technology that alerts parents of potentially unsafe situations.

SensorSafe 2.0 technology integrated into the chest clip sends alerts to both a vehicle receiver and a smartphone. The alerts notify parents when the child has been accidentally left in the car, helping to avoid unthinkable tragedies. Alerts also sound when the child unbuckles themselves in a moving vehicle, when a child has been seated for too long, and when the back seat has become too warm or cool.

Usable from birth to 65 pounds, the Cybex Sirona M includes other features that make the seat easy and comfortable, like a 10-position recline, 12-position headrest and magnetic seat belt holders for easy entry and exit.

In a safety feature unique to Cybex, the seat includes an adjustable linear-side impact protection system—pods that extend from the sides of the seat to absorb up to 25% more energy in a crash. A tubular steel frame runs the perimeter of the seat to provide structural strength, as well as a pathway to channel crash forces away from your child. In addition to meeting American safety standards, the Cybex Sirona M performs in German crash testing with 2.5 times more crash forces than U.S. tests.
