Protection that Grows
The Eternis S All-In-One car seat offers three stages in one-easy to use car seat, suitable from 4 lbs. up to 120 lbs., or 57 inches tall. First used as a rear-facing infant seat up to 50 lbs., then as a forward facing convertible seat and lastly as a belt positioning high-back booster seat. With seamless transitions between modes, the Eternis S offers versatile protection that lasts all the way through your child’s first 10 years of age.
The in-seat recline feature of the Eternis S adjusts to multiple positions, helping to provide a correct ergonomic positioning, a better fit, and extra legroom, allowing your child to safely ride rear-facing longer - up to 50 lbs. The seat comfortably angles the child to help minimize head slump and keep airway open, for a custom, cradled fit.
Integrated Linear Side Impact Protection System (L.S.P.)
The L.S.P. System of the Eternis S extends on the door facing side of the installed car seat and offers increased safety during a side-impact collision. The L.S.P. System reduces the forces of an impact in the event of a side-impact collision by approximately 25% when compared to the same car seat without L.S.P. System.
3-Position Reclining Headrest
The CYBEX patented reclining headrest helps protect the child’s neck and head in the case of a side-impact. This revolutionary technology safely shifts the balance point of the child's head slightly back and prevents it from falling forward when the child is asleep. In the case of a side-impact collision, the child's sensitive head remains within the safety zone of the seat, ensuring optimal protection. Furthermore, our patented 3-position headrest offers a more comfortable sleeping position for a safe and peaceful journey.
12-Position Adjustable Headrest
The 12-position, height-adjustable headrest of the Eternis S offers comfortable protection as your child grows. The integrated no-rethread harness adjusts with the headrest movement so there’s no need to reconfigure the harness as your child moves up in the seat.
Originally developed to prevent the rising number of infant hot car deaths, SensorSafe goes a step further to monitor the well being of the child while the vehicle is in motion.
The Eternis S with SensorSafe provides the essential alert through both the vehicle receiver and the caregiver's cellphone when the driver accidentally leaves the child behind in the car, but also alerts the driver if a child unbuckles themselves while the vehicle is in motion; if the back seat has become too warm or too cold; and if a child has been seated for too long —all through a user-friendly app, that also provides guidance on installation, how-to videos, FAQ’s and more.
