Cybex Sirona S rotating convertible car seat. Purchased new in 2021. Never involved in any accidents. Everything works as it should and nothing is broken or damaged. 360° swivel feature makes getting kids in and out so much easier. Includes the SensorSafe clip/sensor, although we never personally used the app feature. It alerts you if the child unbuckles the chest clip, has been seated too long, or is left in the car. The expiration sticker is worn/faded, but I contacted Cybex and received confirmation it is good until 2030. Could use a cleaning from normal use, but overall in good condition. Smoke-free home.
