Eternis S

Additional Information

  • 12-Position Adjustable Headrest 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. 
  • Adjustable Linear Side-impact Protection (L.S.P. System) absorbs up to 25% more impact forces in the event of a side impact.*
  • Energy Absorbing Shell to help reduce the forces felt by the child in a collision.
  • Magnetic Buckle Holder for easy entry and exit from the seat.
  • 10-position one-hand adjustable recline helps ensure proper angling and best fit to your vehicle seat.
  • Removable newborn inlay provides additional support for babies from 4 lbs. to 11 lbs.
  • The removable cup holder can be positioned on either side and is dishwasher safe for easy clean up.
  • Innovative one-pull LATCH removal system for easy transitions.

SensorSafe Technology

Offered on our online shop and through select retailers, the Eternis S is also available with SensorSafe Technology built into the chest clip. SensorSafe Technology provides essential alerts when unsafe conditions arise, like if a child unbuckles themselves while the vehicle is in motion; if the back seat has become too warm or too cold, if a child has been seated for too long, and if the driver accidentally leaves the child behind after the vehicle has been switched off. These alerts are provided through an installed vehicle receiver and a user-friendly smartphone SensorSafe App, which also provides guidance on installation, FAQ’s, a directly line to customer service and more. Select the Eternis S with SensorSafe from your local retailer for this additional safety feature.
