  • Up to 50% higher safety levels - The Sirona T provides superior protection in both travelling directions in the case of an accident. When in the rear-facing position it reduces the risk of an injury to the child’s neck and head, resulting in 50% higher safety levels*. In the case of an accident, the child is pushed towards the seat shell, where forces get distributed over the entire surface, therefore, reducing the impact. Legally a child must stay rear-facing until at least 15 months and 76 cm in height but we recommend using it for longer, up to four years if possible. The Sirona T's versatility allows for forward-facing positioning once the child has grown, offering freedom of choice that suits you and your child.
  • All-round air ventilation system - Breathable materials keep your little one cool.
  • 360° rotation - effortless on & off boarding - Effortlessly on and off-board your child, thanks to its 360° rotation that smoothly rotates towards the car door. This feature minimizes any potential strain on your back during the boarding process. It’s so simple, using just one hand, the seat can be smoothly rotated and reclined, ensuring that even the youngest passenger is comfortably boarded.
  • Grows with your child- Thanks to its height-adjustable headrest, the safety of the Sirona T evolves with your child, accommodating their rapid growth. With its 12 different positions, the car seat adapts to your child’s size during the first four years, providing steady protection throughout this time. When adjusting the headrest height the harness adjusts automatically to ensure a comfortable fit.
  • 25% More side impact protection - The Sirona T is equipped with the proven Linear Side-impact Protection (L.S.P.) System which enhances safety in the event of an accident. Activate the L.S.P on the side of the car seat nearest the door, together with the energy-absorbing shell of the seat, the extended side protection reduces the initial impact forces by up to 25%**. If needed, the L.S.P. System can be easily stored away in the case of limited space in the car.
  • Comfortable sleeping position - The five recline positions of Sirona T can be easily adjusted with just one hand, freeing up your other hand for different tasks. This feature works in both rear and forward-facing positions, providing additional comfort for your sleeping child while travelling.
  • Harness Magnetics - Small magnets located on either side of the Sirona T, allow you to attach the metal parts of the harness, keeping the straps out of the way for a simpler onboarding.
  • Newborn inlay – support for smaller babies - The Sirona T includes a removable newborn inlay which provides a near-flat lying position, allowing for the use of the car seat from birth in the rear-facing position. The inlay helps keep the baby’s head in the most ergonomic position, especially while sleeping, to avoid breathing complications. To accommodate your baby as it grows, the newborn inlay should be removed once your child is taller than 60cm.
