The CYBEX Eternis S with SensorSafe All-In-One Car Seat offers 10 years of use in one easy-to-use package – making it the only car seat your child will need, from birth and beyond. The SensorSafe technology integrates important next-gen safety features into the chest clip of the car seat to alert you when unsafe situations arise.
The Eternis S offers an adjustable Linear Side-impact Protection (L.S.P. System), which absorbs up to 25% more impact forces in the event of a side-impact collision* and a patented 3-position reclining headrest, which helps prevent the child's head from falling forward while asleep, guiding the head and neck into a safe position. These features, combined with a steel-reinforced frame for strength and durability provide advanced child safety protection and peace of mind.
Suitable from 4 lbs. up to 120 lbs., the Eternis S offers 3 stages of protection – as a rear-facing infant seat up to 50 lbs., a forward-facing convertible seat, and then as a belt-positioning booster that lasts through your child’s first 10 years of age.
How SensorSafe Works: Originally developed to help prevent the rising number of infant hot car deaths, SensorSafe will chime through the installed vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off. This reminds the caregiver to act quickly, but if the child is still secured after several minutes an alert will be sent to the caregiver’s cellphone through the downloaded app. If the situation is still not remedied, the designated emergency contact will receive an alert with the GPS coordinates of the vehicle’s last known position. This state-of-the-art safety technology is designed so there is no need to reinstall each time you drive. For ease, just keep the receiver plugged into your car’s OBD port to drive with that extra peace of mind.
