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 forwardfacing, 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.

Comfort through the whole 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.

One base – two seats

As the foundation of the T-Line Modular System, the Base T can be used with both the Cloud T i-Size and the Sirona T i-Size, for long-lasting protection and versatility. User-friendly ISOFIX release buttons make installation intuitive and easy.

Grows with your child

A newborn inlay provides a near-flat lying position, for safe travel from birth. The baby’s head is kept in the ideal ergonomic position, especially during sleep. The newborn inlay should be removed when your baby grows taller than 60 cm. 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 two-click installation with ISOFIX allows for simple installation and guarantees increased safety. In combination with the Base Z the car seat is secured using the car's ISOFIX system and requires no further fastening. An installation indicator also helps to prevent a possible misuse.

Installation

Installation with base: Pay attention to the i-size logo. If a vehicle seat is marked with this logo, it is suitable for use with all i-size child seats and therefore will not appear in our list of compatible vehicles. If your vehicle does not have an i-Size seat, please check the compatibility of your vehicle. If your vehicle is not displayed, please contact our customer service team.
