The Cybex Eternis S is a three-in-one convertible car seat that can be used rear facing from birth or forward facing for an older child. Unlike many convertible car seats, the Eternis S transforms into a belt-positioning booster seat that your child can use until he or she is ready for the vehicle seat.
The chest clip of the Eternis S also features SensorSafe smart technology, which alerts parents to a variety of potentially unsafe situations via smartphone and car sensors. The Eternis S also features a steel-reinforced base for added safety.
