  • Extended rear-facing travel for enhanced safety, up to 50% safer than forward-facing*
  • Integrated ISOFIX base with smooth 360° rotation for easy access

Suitable from 40 cm with the included newborn inlay, this premium car seat allows children to travel in the safest position possible for as long as possible, while making daily journeys simpler for parents.

Extended rear-facing travel is at the heart of the Sirona Ti’s design. Internal testing shows that rear-facing travel can be up to 50% safer than forward-facing*, using the back of the seat to absorb and distribute crash forces across a larger surface. This not only enhances protection but also creates a calm, cocooned space where children can relax, play or sleep in comfort.

The fully integrated ISOFIX base eliminates the need for additional components and features a smooth 360° rotation. This allows the seat to rotate towards the car door, making lifting a child in and out significantly easier while reducing strain on parents’ backs. Rear-facing use is mandatory up to 15 months (76 cm), with the option to switch to forward-facing thereafter if preferred.

Comfort has been carefully considered at every stage. Ten recline positions in total – five in each driving direction – ensure an ergonomic seating position whether the child is awake or asleep. The seat can remain reclined while rotating, allowing undisturbed transfers from car to home after longer journeys.

Safety is further enhanced by the Linear Side-impact Protection (L.S.P.) system, which works alongside the energy-absorbing shell to reduce side-impact forces by up to 25%**. The L.S.P. elements fold away neatly, making the seat ideal even for smaller cars where space is limited.

As children grow, the height-adjustable headrest adapts effortlessly. With 12 positions and one-handed adjustment, it ensures consistent protection and comfort, while the harness automatically adjusts at the same time for a secure fit. Clever magnetic belt holders keep the harness out of the way when loading, creating a smoother, stress-free routine.

From the very first journey, the Sirona Ti offers a tailored fit. The newborn inlay and wedge provide vital support for babies from 40 to 60 cm, including premature infants. As the child grows, these inserts can be removed in stages, maintaining optimal comfort and posture throughout early development.

All-round air ventilation, enhanced by breathable 3D mesh fabrics, helps regulate temperature in every season. Heat is dispersed through strategically placed vents to keep children cool and comfortable, even on warmer days. For added protection outdoors, the integrated retractable XXL sun canopy offers UPF50+ coverage, shielding from sunlight while improving airflow through its mesh window.

Cybex Siona Ti i-Size Car Seat

A premium 360° rotating i-Size car seat with integrated ISOFIX base, extended rear-facing safety from birth, and adaptable comfort as your child grows.

Integrated ISOFIX Base with 360° Rotation

With its ISOFIX base fully built in, the Sirona Ti offers a seamless all-in-one solution with no additional parts to buy. The smooth 360° rotation allows the seat to turn towards the car door, making it far easier to place a child in or out while reducing strain on parents’ backs during everyday use.

Comfort Features

Ten recline positions, magnetic belt holders and a breathable ventilation system work together to create a calm, comfortable environment. An integrated UPF50+ sun canopy adds protection from bright light and busy surroundings.

Rear-Facing Safety from Birth

Designed to protect from the very first journey, the Sirona Ti supports extended rear-facing travel from 40 cm using the included newborn inlay. Internal testing shows rear-facing can be up to 50% safer than forward-facing*, helping to distribute impact forces more effectively while keeping little ones calm, supported and secure.

Frequently Asked Questions

What age and height range is the Cybex Sirona Ti suitable for?

The Sirona Ti i-Size is suitable from birth at 40 cm, thanks to the included newborn inlay and wedge. It supports children through early toddlerhood, offering a long usage period as your child grows.

Can the Cybex Sirona Ti be used rear-facing and forward-facing?

Yes. The seat is designed primarily for extended rear-facing travel, which is mandatory up to 15 months (76 cm). After this point, parents have the option to switch to forward-facing if they choose, although rear-facing for as long as possible is recommended for maximum safety.

Does the car seat offer sun protection?

Yes. The integrated retractable XXL sun canopy provides UPF50+ protection from harmful UV rays. A built-in mesh window improves airflow while keeping your child shaded and cocooned.

What is the main difference between the Cybex Sirona T and Sirona Ti?

The Cybex Sirona T and Sirona Ti are very similar in terms of safety, comfort and everyday features, with the main difference being how the ISOFIX base is supplied. The Sirona T requires a separate Base T, which allows the seat to be used across multiple compatible CYBEX seats and can be convenient for families who already own the base or plan to reuse it. The Sirona Ti, by contrast, has the ISOFIX base fully integrated into the seat, offering an all-in-one solution with no additional purchases needed. Both models are suitable from birth at 40 cm with a newborn inlay, support extended rear-facing travel, offer 360° rotation for easy access, provide multiple recline positions in both driving directions, and include Linear Side-impact Protection. In everyday use and safety performance, there is no functional difference once installed correctly – the choice largely comes down to whether a modular base system or a fully integrated design is preferred.
