The growing protection
The Eternis S all-in-1 car seat offers three levels of protection for an easy-to-use car seat, which can accommodate a child from 1.8 to 54.5 kg (4 to 120 lb) or 145 cm (57 inches) . Used first as a rear facing seat for babies weighing up to 22.7 kg (50 lbs), then as a convertible front facing seat and finally as a high back booster seat. Thanks to harmonious transitions between modes, the Eternis S offers versatile protection that lasts until your child is 10 years old.

Recline on the seatThe Eternis S seat recline function adjusts in several positions to achieve correct ergonomic positioning, better fit and greater legroom, allowing your child to ride safely backward facing longer, until it weighs 22.7 kg (50 lb). The seat reclines comfortably to help minimize sagging of the head and keep the airways open, for a personalized and comfortable seat.

Integrated Linear Side Impact Protection System (LPS)
The Eternis S LSP system deploys to the side facing the door when the seat is installed in a vehicle and provides increased safety in the event of a side impact. The LSP system reduces the impact force in a side collision by around 25% compared to the same car seat without LSP

3-position tilting headrest
CYBEX's patented tilting headrest helps protect the child's neck and head in the event of a side impact. This revolutionary technology safely moves the balance point of the child's head slightly back and prevents the child from falling forward when asleep. In the event of a side collision, the sensitive part of the head remains in the seat safety zone, ensuring optimum protection. In addition, our patented 3-position headrest provides a more comfortable sleeping position for a safe and peaceful journey.
