Cybex Sirona T i-Size - safety and comfort, facing backwards and forwards

Look forward to the ultimate travel experience with the Sirona T i-Size - a rear-facing child seat that offers incomparable comfort and maximum safety, making every trip a pleasure for you and your child. The all-round air circulation ensures a pleasant temperature in the seat at any time of the year, while the 360 degree rotation allows your child to sit in and lift out effortlessly. Thanks to the easy rotation, you can also choose between the safer rear-facing and the comfortable forward-facing seating position. In addition, the seat can be adjusted with just one hand, so that you have the other hand free. The integrated linear side impact protection and ISOFIX make every journey even safer.

Up to 50% more security*
Cybex recommends using the seat rear-facing beyond the mandatory first 15 months (76 cm) and up to age 4 if possible. The flexibility of the Sirona T i-Size enables forward-facing driving as soon as the child has reached the appropriate size. (*Compared to the same forward-facing seat in a frontal impact. Result of internal tests using the criteria of the ADAC frontal crash test 2022.)

Optimal breathability
The Sirona T i-Size offers all-round air circulation for maximum seating comfort. In the Plus line, air circulation has even been improved, as the specially developed 3D mesh structure of the cover increases breathability by up to six times*. The Plus line also offers a sun canopy with mesh inserts - for perfect sun protection. (*Compared to conventional child seat covers.)

Quick and easy entry and exit
With the Sirona T i-Size you can lift your child in and out effortlessly, because with the 360 degree rotation it can easily be turned towards the car door. It is mandatory to use the Sirona T i-Size in the rear-facing position for at least the first 15 months (76 cm). If your child is older, you can choose between the backward and the forward-facing position.


More Highlights
A comfortable position for every travel situation
The five inclination settings of the Sirona T i-Size can be adjusted with just one hand, leaving your other hand free for other things. The settings can be used both in the backward and forward-facing position as well as in the 360 degree rotating mechanism and offer your sleeping child all the comfort with every ride.

25% more side impact protection
The Sirona T i-Size is equipped with the proven linear side impact protection (L.S.P.), which increases your child's safety in the event of an accident. Together with the seat's energy-absorbing shell, the L.S.P. system reduces impact forces by up to 25%*. If there is not enough space in the car, the side impact protection can be easily stowed away. (*compared to the same seat without L.S.P. in the side impact test according to ADAC criteria.)

Grows with your child
Thanks to the height-adjustable headrest, the Sirona T i-Size grows with your child and accompanies it safely through every growth phase. With a total of 12 different positions, the child seat can be optimally adjusted during the first four years of your child's life and always offers reliable protection during this time.

Ergonomic fit, even for the little ones
The Sirona T i-Size has a removable newborn insert that allows an almost flat lying position. The rear-facing child seat can be used from birth. The insert helps to keep the baby's head in an ergonomic position. It should be removed as soon as your child is larger than 60 cm.

Easy entry and exit
Small magnets located on the side of the Sirona T i-Size allow the straps to be conveniently attached while you put your child in or lift them out. This makes boarding and alighting a breeze.

Intuitive installation
The Base T serves as a secure basis for the Sirona T i-Size. It is equipped with ISOFIX and a support leg for easy and safe installation. The optimized ISOFIX unlocking buttons can be operated intuitively and visual indicators show correct installation. The seat can thus be installed in just a few simple steps.
