Design, safety and functionality are at the heart of innovation at CYBEX. The Base Z is the secure and variable base unit for the new CYBEX Z-Line Modular System, which offers maximum protection as well as comfortable, flexible use. The unique, innovative rotation mechanism of the Base Z allows the car seat to be swivelled to the side of the car door for easier entry and exit.

The Base Z is a particularly long-lasting solution. It accommodates two different car seats and so can be used by children up to 4 years of age. The CYBEX Platinum Modular System is quickly installed with a simple click.


For maximum safety, we recommend using the Sirona Z in a rear-facing position for as long as possible – 45 – 105 cm, max. 18 kg (from birth up to approx. 4 years).

Physicians, accident researchers, and consumer and health organizations recommend transporting babies and toddlers in rear-facing car seats. In most countries, car accidents are still the main cause of death for children older than 1 year of age. However, if children are transported rear-facing beyond Group 0+, the risk of injury is mostly stable in Group 1. This can be seen in statistics from countries with predominantly rear-facing transport in Group 1, such as Sweden.

It is important to consider the anatomy of babies and toddlers in the event of an accident. Unlike adults, a child’s head is quite large and heavy in proportion to their body, and accounts for about 25% of their total body weight. However, the neck muscles and the spine of a child are not yet fully developed. That is why they need particular support and protection in an accident. CYBEX developed the Sirona Z to provide infants and toddlers with maximum safety in the car. In an accident, the Sirona Z acts like a protective shield, especially protecting the neck and spinal area. The impact forces are distributed over the large area of the shell. This significantly reduces strain on your child’s neck, shoulder and head as well as their inner organs. Therefore, the Sirona Z greatly reduces the risk of physical injury in a frontal collision.
