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.

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 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.

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 seats 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.

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+).
