Designed for the beautiful in-between years, the Cybex Sirona G3 Plus Car Seat brings reassurance, comfort and ease to every journey. Created to support your child from infancy through to approximately 4 years, the Sirona G3 Plus combines extended rear-facing safety with smart everyday functionality.
