Between its innovative safety technology and ability to grow with your child from birth to 120lbs, the Cybex Eternis S Convertible Car Seat may be the only car seat your child ever needs. The Eternis S is a 3-in-1 car seat that can be used rear-facing or forward-facing. When your child is ready the Eternis S easily transforms into a belt-position booster seat.    

    • Includes SensorSafe™ Technology - Once attached to the harness system of your car seat, the 4-in-1 kit connects to your smartphone and provides essential alerts to help prevent critical situations like when your child unbuckles the clip and more
    • Linear Side-impact Protection absorbs impact forces of certain side impact crashes and directs these forces into the energy absorbing shell of the car seat away from baby's sensitive neck area
    • In-seat recline adjusts to multiple positions, helping to provide a correct ergonomic position, a better fit, and extra legroom, allowing your child to safely ride rear-facing longer - up to 50lbs. The seat comfortably angles the child to help minimize head slump and keep airways open, for a custom, cradled fit 
    • Features a magnetic buckle holder for easy entry and exit along with an innovative one-pull LATCH removal system for easy installation and removal from the vehicle seat
    • Removable cup holder can be positioned on either side and is dishwasher safe for easy clean up
