The CYBEX Eternis S 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. 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.

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.

Weight capacity:

  • Rear: 4-50lbs

  • Forward: 22-65lbs

  • Booster: 40-120lbs
