Cybex Sirona Ti i-Size 360° Car Seat with Integrated ISOFIX Base

Designed for parents who refuse to compromise on safety, comfort or ease of use, the CYBEX Sirona Ti i-Size is a premium 360° rotating car seat that protects your child from birth up to approximately 4 years (40–105 cm, max. 19 kg). Combining extended rear-facing travel, advanced side-impact protection and an integrated ISOFIX base, the Sirona Ti i-Size delivers next-level innovation for every journey.

Safer Travel with Extended Rear-Facing Protection

Safety is at the heart of the Sirona Ti i-Size. Rear-facing travel is proven to be significantly safer than forward-facing, helping to protect your child’s head, neck and spine in the event of a collision. By using the back of the seat as a protective buffer, impact forces are distributed over a larger surface area, reducing strain during sudden deceleration.

Rear-facing travel is mandatory until 15 months (76 cm), after which parents may choose to rotate the seat forward-facing if desired. Thanks to the fully integrated base and smooth 360° rotation, switching directions is effortless while maintaining optimal safety at every stage.

Integrated ISOFIX Base with 360° Rotation

The Sirona Ti i-Size features a fully integrated ISOFIX base, eliminating the need for additional purchases and ensuring a secure, straightforward installation every time. The intuitive 360° rotation allows parents to turn the seat toward the car door, making it significantly easier to lift your child in and out of the car — ideal for everyday use and longer journeys.

Once secured, the seat locks confidently into position for travel, delivering peace of mind alongside everyday practicality.

Linear Side-Impact Protection for Enhanced Safety

In the event of a side collision, the Linear Side-Impact Protection (L.S.P.) System works together with the energy-absorbing shell to reduce impact forces on your child. The foldable design also allows flexibility in smaller vehicles, folding away neatly when space is limited without compromising protection.

Ergonomic Comfort from Newborn to Toddler

Comfort is engineered into every detail of the Sirona Ti i-Size. The included newborn inlay and wedge provide optimal ergonomic support from 40–60 cm, making the seat suitable even for premature babies. As your child grows, the wedge can be removed at 48 cm and the inlay at 60 cm, ensuring a perfect fit at every stage.

With five recline positions in both rear- and forward-facing modes, your child enjoys consistent ergonomic comfort whether sitting upright or sleeping peacefully. The seat can remain reclined while rotating, so your child can continue sleeping undisturbed when transitioning from car to home.

Height-Adjustable Headrest with Automatic Harness Adjustment

The 12-position height-adjustable headrest adapts easily as your child grows, keeping them properly positioned and better protected in the event of a side impact. Each adjustment automatically adapts the harness, ensuring a secure fit without re-threading. The one-handed adjustment system makes changes quick and effortless for parents.

Breathable Design with All-Round Air Ventilation

To keep your child comfortable all year round, the Sirona Ti i-Size features all-round air ventilation using advanced 3D mesh fabric. This allows air to circulate through the seat, dispersing heat and reducing the risk of overheating on warmer days, helping your child stay cool and comfortable on every journey.

Integrated UPF50+ XXL Sun Canopy

The retractable UPF50+ XXL sun canopy protects your child from harmful UV rays while creating a calm, cocooned space inside the car. An integrated mesh window improves airflow, while the adjustable design allows the canopy to be repositioned as the sun moves throughout the day.

Thoughtful Details for Everyday Ease

Practical features such as magnetic belt holders keep the harness out of the way while placing your child in the seat, making everyday use faster and less stressful. Combined with intuitive rotation and recline controls, the Sirona Ti i-Size is designed to make every journey simpler and more enjoyable.
