The Cybex Sirona S is the convertible car seat that protects your child?and?your back. The car seat rotates?360 degrees,?allowing you to rotate the seat toward your car door while helping your child in and out.

Because the Sirona S can swivel?from rear-facing to forward-facing, you may only need to install it a single time using the vehicle seatbelt and EasyLock system for a simple and secure installation.

The Cybex Sirona S is also the only American convertible car seat with a load leg, a metal bar that extends from the base of the seat to the floor of your car to inhibit movement and prevent head injury.

Energy-absorbing pods that extend from the sides of the seat to absorb 25% more forces in a crash, while?SensorSafe technology integrated into the chest clip sends safety alerts to both a vehicle receiver and a smartphone. The alerts notify parents to potentially dangerous situations, like a child being left in a car, an unbuckled chest clip, unsafe temperatures or a child seated for too long.

With features like a no-rethread harness, included cup holder and numerous recline positions, the Cybex Sirona S offers the ultimate in convenience and safety for your child from birth to 65 pounds.
