CYBEX products undergo hundreds of crash tests every year, so they can be continuously improved. Our car seats are regularly tested and evaluated by independent testing institutes. We are proud that our car seats score excellent marks in leading European safety and consumer tests, for example by the ADAC and Stiftung Warentest.


At the heart of all CYBEX products is our D.S.F. Innovation Principle. This stands for a product line that combines clear, unique Design with unsurpassed Safety and intelligent Functionality. We have compiled some of our most important security principles here:

CYBEX Safety Center


Peace of mind for you, ultimate safety for your child. CYBEX fuses smart technology and smart design with the introduction of SensorSafe: a unique child monitoring system that ensures the safety and health of your child is always your first priority. Available also for Cloud Z i-Size and Sirona Z i-Size, the SensorSafe clip attached to the harness system, keeping you informed of the safety and health of your seated child at all times.

CYBEX Z-LINE Modular System

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.

Cloud Z i-SIZE

UN R129/02, 45 – 87 cm, max. 13 kg (birth – approx. 24 months)

Ergonomic lie-flat position

The Cloud Z i-Size can be changed to a lie-flat position outside of the car. This feature allows your child to lie comfortably in an ergonomically correct position. The seat was specially engineered to meet the needs of even the most delicate newborns and premature babies whose neck muscles and reflexes are not yet fully developed.

Easy boarding position

Easy boarding position – The innovative rotation mechanism of the Base Z makes it easy to swivel the Cloud Z i-Size towards the car door, making it easier to get your child in and out of the car.

Side-impact Protection

Integrated L.S.P. System – For the Cloud Z i-Size, our tried-and-tested Linear Side-impact Protection (L.S.P.) System has been improved even further. The very first impact forces of an accident are reduced by the extended side protector that faces the door.

Sirona Z i-Size

UN R129/02, 45 – 105 cm, max. 18 kg (birth – approx. 4 years)

Easy Boarding Position

Rotation mechanism – The innovative 360° rotating mechanism makes it easier to get your child in and out of the car, ensuring less strain on your back.


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

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 i-Size greatly reduces the risk of physical injury in a frontal collision.

Side-Impact Protection

Integrated L.S.P. System – Evidence has shown that the lateral space of a vehicle is limited and does not guarantee protection within the crumple zone. That’s why the CYBEX Sirona Z i-Size features the L.S.P. System, an adjustable side-impact protection system that increases safety.

Solution Z i-Fix

UN R129/03, 100 - 150 cm (approx. 3 – 12 years)

Patented Reclining Headrest

The patented, 3-position reclining headrest is an essential feature of the Solution Z i-Fix safety concept. The headrest can be tilted to shift the heads center of gravity so that it is unlikely to fall forward while your child sleeps. In a side-impact collision, the head and side-impact protectors keep your child’s sensitive head and neck area safe in the seat’s safety zone.

Automatic Height and Width Adjustment

Individual comfort – Most children reach 55% of their total height by the age of 3, and by the age of 12 have completed 89% of their growth. This means they grow an average of 60 cm during the period in which a car seat should be used. To provide the best possible protection and comfort for the entire duration of use, the new CYBEX Solution Z i-Fix features integrated height and width adjustments.

Stay Cool

Air ventilation system – The integrated air ventilation system of the Solution Z i-Fix provides a comfortable seat temperature, even on hot days.
