The Cybex 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 4 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).
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 accomodate their rapid growth. 12 different headrest positions let you adapt the car seat t
