Cybex introduces their newest addition to the Gold Car Seat family, the Sirona M with SensorSafe 2.0, an easy-to-use convertible car seat that offers leading-edge child safety protection from birth to childhood. The most impressive addition to the car seat is their state-of-the-art chest clip that alerts you through your vehicle receiver and your cell phone when an unsafe situation arises. By combining crucial elements of safety technology into the chest clip, the Linear Side-Impact System, and a 12-position height adjustable headrest with integrated no-rethread harness your mind will be at ease knowing that your child has the ultimate protection throughout their childhood.Over the years there has been a rising number of infant hot car deaths, a sad and alarming statistic, but one that can be changed. The SensorSafe 2.0 was originally developed to help prevent this horrific tragedy from happening by monitoring your child while in the car. You will be alerted through a user-friendly app if your child unbuckles themselves while the vehicle is in motion; if the back seat has become too warm or too cold; and if a child has been seated too long. If an emergency contact is needed they will receive GPS coordinates of the vehicle's last known position. The app can be downloaded for Android and IOS. The Sirona M with SensorSafe 2.0 doesn't stop at the chest clip when it comes to protecting your child, they've also included the L.S.P System (Linear Side Impact Protection System). This system protects your little one whether they are facing rearward or forward-facing and can even be individually adjusted to absorb up to 25% more impact on the door facing side in case of a side impact collision. The 12 position height adjustable headrest and the one-hand adjustable recline in 10 positions help to ensure the proper fit to your vehicle. The integrated harness guide changes automatically when the headrest is adjusted preventing any misuse of the harness whilst adding an even more protective barrier to the side-impact protection system. The Sirona M with SensorSafe 2.0 even comes fully protected for your newborns and premature babies. They provide a removable newborn inlay that helps prevent your baby's head from tipping forward while they sleep and reducing the risk of suffocation due to the safe lying angle between head, neck, and chest. The insert is removable after the child reaches 11lbs, to provide more space and comfort for growing children. From Birth up to 65 lbs, the Cybex Sirona M with SensorSafe 2.0 is top of the line for safety and protection that will give you the extra peace of mind you deserve.
