Eternis S SensorSafe All-in-One Convertible Car Seat
The CYBEX Eternis S with SensorSafe™ is the only car 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 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 that guides your child’s head into a safe and comfortable position. With the addition of SensorSafe™ technology, you'll gain instant insight into your child’s well-being—right to the SensorSafe app on your phone.
