Cybex Sirona T I-size in Sepia Black (comfort)


Sirona T i-Size

Awarded a “Good” rating in the ADAC test, the Sirona T i-Size rear-facing car seat features all-round air ventilation. Choose the Plus option for an integrated sun canopy. Only compatible with the Base T or Base Z2.
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 2,022 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.
