The CYBEX Eternis S is the only car seat that you'll need for your child. As a 3-stage all-in-one car seat, the Eternis S can be used as a rear-facing infant seat, then as a forward facing convertible seat and finally as a belt-positioning booster seat. 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.

Featuring the innovative SensorSafe technology to help prevent infant deaths in hot vehicles.  SensorSafe works by chiming the installed vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off.  If no action is taken by the caregiver, then an alert is sent to the caregiver's cellphone through a downloaded app.  Finally, if required, a designated emergency contact will receive an alert with GPS coordinates of the vehicle's last known location. 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.

This is a Final Sale Product. No returns or exchanges.
