Installation with base: Pay attention to the i-size logo. If a vehicle seat is marked with this logo, it is suitable for use with all i-size child seats and therefore will not appear in our list of compatible vehicles. If your vehicle does not have an i-Size seat, please check the compatibility of your vehicle. If your vehicle is not displayed, please contact our customer service team.
*Please note that the Sirona T i-Size may have limited recline functionality when used with the Base Z*
Up to 50% higher safety
The Sirona T i-Size is a rear-facing car seat providing superior accident protection, reducing the risk of head or neck injury and improving safety by 50% (compared with the same seat forward-facing; results of testing using 2022 ADAC criteria). In a crash, the child is pushed towards the seat shell, where forces are distributed and lose impact. Rear-facing is mandatory for at least 15 months (76 cm tall). After that you are able to rotate the Sirona T-Size forward-facing, although, we recommend rear-facing travel for up to four years if possible.
All-round air ventilation provides year-round comfort. And the Plus fabric version has even better airflow, with a 3D mesh that increases breathability up to six times (compared to conventional fabric). The Plus line also features a sun canopy with mesh inserts to keep your child cool and protected.
Easy on and off-boarding
Get your child in and out of the car with ease. 360° rotation lets you swivel the Sirona T i-Size smoothly towards the car door with one hand, for easy boarding and less back strain. Rear-facing is mandatory for at least the first 15 months (up to a height of 76 cm). Then you can keep your child rear-facing or turn them forwards for extra comfort.
Comfort throughout their journey
The Sirona T i-Size features five recline positions in both rear and forward-facing positions. It can also recline while rotating on its base. Reclining the seat requires only one hand, keeping your other hand free for different tasks.
25% more side-impact protection
A proven Linear Side-impact Protection (L.S.P.) System enhances safety in the event of a side crash. Together with the car seat’s energy-absorbing shell, the L.S.P. reduces initial impact force by up to 25% (compared to the same seat without L.S.P. using ADAC test criteria). The L.S.P. System folds away if space in the car is limited.
Grows with your child
The Sirona T i-Size evolves with your child, thanks to a height-adjustable headrest designed to accommodate their rapid growth. 12 different headrest positions let you adapt the car seat to your child’s size during their first four years, providing steady protection throughout this time.
Good for the youngest travelers
A newborn inlay provides a near-flat lying position, for safe travel from birth. The baby’s head is kept in the ideal ergonomic position, especially during sleep. When your baby grows taller than 60 cm, the newborn inlay should be removed.
Magnets let you attach the buckle tongues to the sides of the the Sirona T i-Size, keeping the belts out of the way as you get your child in or out of the car seat. Simplified on-boarding for a stress-free experience.
Intuitive installation and anchorage
A secure base for the Sirona T i-Size. The Base T is equipped with ISOFIX and a load leg for quick and stable installation. User-friendly release buttons feature visual indicators helping you confirm the base is set up correctly. Set-up is as easy as it gets, helping ensure a safe and comfortable ride.
Reliable UPF50+ protection
A UPF50+ sun canopy gives your child excellent sun protection, even in the car. For warmer days, the sun canopy is equipped with mesh inserts, for breathability and cool airflow (sun canopy included with Plus line only – mesh parts are not UPF50+).
