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 can rotate the Sirona T-Size forward-facing, although, we recommend rear-facing travel for up to four years if possible.

Optimal breathability
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 in, easy out
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 forward-facing for extra comfort.

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.

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.
