The CYBEX Sirona M Convertible Car Seat has two modes - rear-facing from 5 lbs. to 40 lbs. and forward-facing from 22 lbs. to 65 lbs. This seat provides comfort and maximum safety with patented Side-impact Protection which can reduce side impact forces by up to 25%*, an energy absorbing shell and a 12-position height adjustable headrest with a no-rethread harness that offers protection that grows with your child.
Linear Side-Impact Protection (L.S.P.)
The L.S.P. System of the Sirona M and Sirona M with SensorSafe 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. extended..
12-Position Height Adjustable Headrest
The 12-position, height-adjustable headrest of the Sirona M and Sirona M with SensorSafe 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.
