Cybex Sirona G3 360° Car Seat COMFORT | i-Size – Magic Black

About the Cybex Sirona G3

The Cybex Sirona G3 is a premium 360-degree rotating i-Size toddler car seat engineered to keep your child safer, more comfortable, and properly supported from approximately 3 months all the way through to 4 years of age. Combining award-winning ergonomic design with advanced safety technology, the Sirona G3 is independently recognised by the AGR (Aktion Gesunder Rucken e.V.) for its ability to support healthy back development and reduce strain for both child and parent alike.

Rear-facing travel is the safest way for young children to ride, and the Sirona G3 makes it practical for everyday use. Its 360-degree rotation mechanism lets you position your child at a comfortable angle for boarding and alighting, removing the need to bend awkwardly into the car. Whether you are navigating a busy car park or heading out on a long journey, the Sirona G3 is designed to make every trip easier and every ride safer.

Key Features

• Up to 50% Higher Safety Levels Rear-Facing: When used in the rear-facing position, the Sirona G3 delivers up to 50% better protection compared to a conventional forward-facing seat (based on internal testing). The padded shell absorbs and distributes impact forces in a frontal collision, reducing strain on the child’s neck and limiting movement.
• 360-Degree Rotation: Rotate the seat a full 360 degrees to position your child perfectly for getting in or out of the car, even when the seat is reclined. Far quicker and kinder on your back during daily use.
• 25% More Side-Impact Protection: The advanced Linear Side-Impact Protection (L.S.P.) System, combined with an energy-absorbing shell and specially designed headrest, provides 25% more protection in a side collision (based on internal testing). The L.S.P. System opens automatically when removed from the box and can be folded away if space in the car is limited.
• Ergonomic M-Position Seating: The seat is specially designed to hold your child’s legs and hips in the posture-friendly M-position, supporting healthy development as they grow.
• Modular G3 Compatibility: As part of the Cybex Modular G3 family, the Sirona G3 shares a base with the Cloud G3 infant car seat. When your child outgrows the Cloud G3, the Sirona G3 clicks onto the same Base G3 with just one click, providing a continuous, secure travel solution for the first four years.
• ISOFIX and Load Leg Installation: The Base G3 anchors securely to the vehicle using ISOFIX connectors and a load leg, providing a stable and safe foundation.
• Suitable from Birth: When used with the separately available Sirona G Line Newborn Inlay (sold separately), the seat can be used from birth (from 40 cm child height).
• Optimal Breathability: Breathable fabrics keep your child comfortable throughout every journey.
• Machine Washable Cover: The fabric cover can be removed and machine washed at 30 degrees C for easy maintenance.
• AGR Seal of Approval: Recognised by the independent German AGR organisation for its ergonomic design and functionality.
