Highlights

  • 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, reducing the impact. Legally a child must stay rear-facing until at least 15 months and 76 cm in height, though rear-facing is recommended for up to four years if possible. The Sirona T's versatility allows for forward-facing positioning once the child has grown.
  • All-round air ventilation system – plus fabric only - The Sirona T PLUS provides all-round air ventilation for year-round comfort. Air circulation and comfort are enhanced due to a specially designed 3D mesh structure that increases breathability up to six times**. The sun canopy features mesh inserts to keep the child cool and protected.
  • 360° rotation - effortless on & off boarding - The Sirona T features 360° rotation that smoothly rotates towards the car door to assist with on and off-boarding. The seat can be smoothly rotated and reclined using one hand.
  • Integrated UPF50+ fabric sun canopy – plus fabric only - The integrated sun canopy on the Sirona T Plus is made of UPF50+ fabric**** and offers sun protection in the car. The sun canopy moves with the headrest and can be folded back and tucked away. For warmer days, the sun canopy is equipped with mesh inserts for breathability and ventilation.
  • Grows with your child - The height-adjustable headrest allows the safety of the Sirona T to evolve with the child. With 12 different positions, the car seat adapts to the child’s size during the first four years. 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 Linear Side-impact Protection (L.S.P.) System. When activated on the side of the car seat nearest the door, the L.S.P. system, together with the energy-absorbing shell of the seat, reduces the initial impact forces by up to 25%***. The L.S.P. System can be stored away if needed.
  • Comfortable sleeping position - The five recline positions of the Sirona T can be adjusted with one hand. This feature works in both rear and forward-facing positions.
  • Harness Magnetics - Small magnets located on either side of the Sirona T allow the metal parts of the harness to be attached, keeping the straps out of the way for 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 an ergonomic position. The newborn inlay should be removed once the child is taller than 60cm.
