Designed to keep your child safer for longer, the Cybex Sirona G i-Size Car Seat offers up to 50% higher safety levels in a frontal crash when used rear-facing*. Paired with the Cybex Base G (sold separately), the Sirona G features a 360° rotation mechanism, allowing for stress-free on-and-off boarding and seamless transitions between rear- and forward-facing positions.

Part of the Cybex Modular G Line, the Sirona G combines intelligent safety features, breathable comfort, and flexible installation into a sleek, easy-to-use design that supports your child from birth to 4 years (40–105 cm with newborn inlay).

The Cybex Sirona G i-Size is designed for families prioritising safety without compromising on comfort or convenience. Used rear-facing with Base G, it offers superior protection in frontal collisions, while the 360° rotation makes placing your child in and out of the seat effortless.

Suitable from 3 months to approx. 4 years (or from birth with the optional newborn inlay), the Sirona G provides five recline positions, one-handed operation, and an adjustable headrest to support growing children. Built-in Linear Side-Impact Protection (L.S.P.) offers enhanced crash protection without the need for bulky external components, and a full air ventilation system, including breathable mesh fabric, keeps your little one cool and content in all seasons.

Compatible with the Cybex Base G, which also supports the Cloud G infant seat, this modular car seat ensures continued convenience and safety from birth through toddlerhood.
