The CYBEX Eternis S with SensorSafe™ is the only seat your child will need from birth and beyond. With three modes - rear-facing, forward-facing, and booster, this All-In-One Convertible Car Seat is designed for use from birth up to 120 lbs. The Eternis S with SensorSafe features Linear Side-impact Protection, and a patented 3-position reclining headrest that guides the child’s head and neck into a proper position while they are asleep. With SensorSafe™ technology, you'll gain instant insight into your child's well-being—right to the SensorSafe app on your phone. Built into the chest clip of CYBEX car seats, SensorSafe provides alerts when unsafe situations arise including if a child unbuckles themselves; if the back seat has become too warm or too cold if a child has been seated for too long, and if the driver accidentally leaves the child behind.
- Rear-facing from 4 lbs. to 50 lbs. Forward-facing from 22 lbs. to 65 lbs., Belt-positioning Booster from 40 lbs. to 120 lbs.
- SensorSafe™technology uses a Bluetooth-enabled chest clip to send mobile app alerts when potential unsafe situations arise (not used in Belt-positioning Booster mode).
- Linear Side-impact Protection absorbs up to 25% more impact forces in a collision (when compared to the same car seat without L.S.P. extended).
- Patented 3-position reclining headrest helps prevent the child's head from falling forward while asleep, keeping the head and neck in a proper position.
- In-seat recline provides correct ergonomic positioning and extra legroom, allowing your child to ride rear-facing longer.
