Condition: Used and very clean. Suitable from 1 to 4 years old. The Sirona model is well-known and safe. It is supposed to be from birth to approximately 4 years old (up to 18 kg) due to the 360-degree rotation feature. Unfortunately, after washing the seat at the cleaning service, the rotation system malfunctioned, and it is now fixed in one forward-facing position (from one year old onwards). Therefore, it cannot be used from birth. The YouTube clip shows the model; YouTube video title: Rear facing car seat CYBEX Sirona Installation video Color: Black The seat has been cleaned and washed at the distinguished cleaning service on King Fahd Road, and it is ready for immediate use. For those who wish, I can send video clips privately.
