SensorSafe™ Technology

With SensorSafe™, you'll gain instant insight into your child's well-being—even when your eyes are on the road. Built into the chest clip of CYBEX car seats, the SensorSafe clip connects to a vehicle receiver which sends alerts about your child's safety, right to the mobile app on your phone. It's the kind of unparalleled safety technology you've come to expect from CYBEX.

Linear Side-impact Protection (L.S.P.)

Linear Side-impact Protection (L.S.P.)
Linear Side Impact Protection is a feature of CYBEX car seats that absorbs impact forces of certain side impact crashes and directs these forces into the energy absorbing shell of the car seat and away from the child’s sensitive neck area. By extending the L.S.P. system on the side of your car seat facing the door, this feature takes the initial brunt of the force and helps keep your child safer in the event of a near side impact.

Car seats with L.S.P. extended see a reduction in near side impact forces on the baby by up to 25 % when compared to the same car seat without L.S.P. extended.

Patented 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. Furthermore, our patented 3-position headrest offers a more comfortable sleeping position.

In-Seat Recline

In-seat recline provides correct ergonomic positioning and extra legroom, allowing your child to ride rear-facing longer - up to 50 lbs.

12-Position Height-adjustable Headrest

With the 12-position height-adjustable headrest with integrated harness guide, the length of the harness changes automatically when the headrest is adjusted. This eliminates the need for the difficult re-threading of the harness and makes it almost impossible to misuse.

6-Position Recline

6-position one-hand adjustable recline for the best fit to your car

Magnetic Buckle Holders

Magnetic buckle holders for easy entry and exit from the seat
