The CYBEX Eternis S all-in-one convertible car seat is a must-have for keeping your child safe and comfortable while on the road. Designed to grow with your child, this infant car seat provides up to 10 years of use, transitioning from a rear-facing position to a forward-facing seat and finally to a belt-positioning booster for children up to 120 lbs.

Featuring the innovative SensorSafe technology, the Eternis S automatically syncs with the app on your phone to provide alerts if any unsafe situations arise. This includes if your child becomes unbuckled, the back seat becomes too warm or cold, or if the child has been seated in the infant car seat for too long.

For added safety, the Eternis S is equipped with Linear Side Impact Protection (L.S.P.), which reduces side impact collision forces by up to 25% compared to the same seat without L.S.P. This ensures your little one is well-protected in the event of a collision.

Comfort is also a priority with the Eternis S. The patented reclining headrest helps prevent your child's head from falling forward while they sleep, keeping the head and neck in a safe position. Additionally, the in-seat recline provides extra legroom, allowing your child to ride rear-facing for longer.

The seamless transitions between the different modes of the Eternis S provide up to 10 years of use, making it the only car seat your child will need from birth and beyond. The seat can be converted into a belt-positioning booster seat, ensuring your child has an age-appropriate seat as they grow.

In summary, the CYBEX Eternis S all-in-one convertible car seat is a comprehensive solution for keeping your child safe and comfortable on the road. With its advanced safety features, innovative technology, and adaptable design, it is a must-have for any family with growing children.
