The Cybex Sirona T i-Size is suitable from birth to 4 years (approx.), offering exceptional safety and comfort, and ensuring your child is protected in both directions. Children can stay rearward-facing up to 105cm (4 years approx.) or the seat can be positioned to be forward-facing from 16 months.

The Sirona T i-Size can rotate 360° with just one hand, providing a seamless solution for parents to effortlessly embark and disembark their child. Easily swivelling towards the vehicle door, this feature significantly reduces the risk of any physical back strain and allows a smooth transition from rear to forward-facing positions. Rotating and reclining the Sirona T i-Size is completely fuss-free, meaning your little one will travel in the utmost comfort.

The telescopic Linear Side-impact Protection (L.S.P) in conjunction with the energy absorbing shell reduces the force of a side impact collision by approximately 25%, providing additional safety for your child.

The one-hand recline with 5 reclining rear-facing positions and 3 reclining forward-facing positions ensure your little one is comfortable whilst travelling in the car or napping. The 12-position height-adjustable headrest adapts to your growing child and the harness adjusts simultaneously for the most comfort.

The included removable newborn inlay offers a near-flat lying position for your newborn to prevent your baby’s head from tipping forward and causing breathing difficulties. The newborn inlay is suitable for use up to 60cm in height.

The Plus edition of the Sirona T i-Size features 3D mesh fabric for a more breathable and comfortable environment all year round. The built-in UPF50+ sun canopy protects your little one from the sun’s harmful rays, whilst the mesh inserts improve ventilation to ensure they are cool and comfortable in the warmer months. Perfect for your growing child, the sun canopy moves with the headrest, and can easily be folded away when not in use.

The Base T (sold separately) enables effortless installation, providing ISOFIX with intuitive release buttons and a load leg to supply increased stability and safety. The visual indicators confirm you have installed your Sirona T i-Size correctly for that peace of mind.
