A UNIQUE SMART CLIP THAT ENHANCES THE SAFETY OF YOUR CHILD SEATED IN THE CAR

Peace of mind for you, ultimate safety for your child. CYBEX fuses smart technology and smart design with the introduction of SensorSafe: a unique child monitoring system that ensures the safety and health of your child is always your first priority. Available for several Platinum and Gold i-Size car seats, the SensorSafe clip attached to the harness system, keeping you informed of the safety and health of your seated child at all times.

SensorSafe provides essential alerts to help prevent critical situations: when your child unbuckles the clip, when the ambient temperature of your child is too hot or too cold, if your little one is left unattended in the car, and if your child has been seated for too long. All alerts are received via Bluetooth on your smartphone through a user friendly app that also provides guidance on installation, how-to videos, FAQs and more.
