Sirona Z11

360° rotating mechanism

Provides a comfortable entry and exit position with less strain on parent’s back.

In addition it makes switching between rear- and forward-facing position easy.


Rear-facing car seat

When positioned rear-facing, the seat significantly reduces the risk of injury in case of a head-on collision. The Sirona Zi i-Size allows you to transport children rear-facing from birth up to a height of 105 cm (up to 18 kg, approx. 4 years). Depending on your preference, the Sirona Zi i-Size can also be used as a forward-facing car seat for children (starting from min. 76 cm and 16 months up to 105 cm). However, CYBEX recommends that children travel rear-facing in the Sirona for as long as possible.


Integrated Side-impact Protection

Offers increased safety in the event of a side-impact collision. It reduces the force of a side-impact in combination with the energy-absorbing shell by approx. 25%.



Energy Reduction Technology

Offers increased safety for your child in the forward-facing position in the event of a head-on collision. The “ER-Tech” reduces the forces on the neck of a child during a front crash by more than 20%, compared to other existing 5-point harness system.



Height-adjustable headrest


Offers 12 positions for a customized adjustment as your child grows.



One-hand recline

Makes it easy for parents to adjust the seat while keeping one hand free. For comfortable sleeping and traveling,


The newborn inlay allows an ergonomic lying position and now features head and side padding that forms

a cozy nest around the smallest babies for extra support and soft comfort.


5-point harness system


Secure your child in the Sirona Zi i-Size with ease.
