Cybex Sirona Q Rear-Facing Car Seat


The CYBEX Sirona Q car seat offers safe rear-facing travel from birth up to 4yrs.

Full description


Fully compliant with the latest European i-Size ECE R129 regulations for car seats, the CYBEX Sirona Q car seat offers safe rear-facing travel from birth up until four years or from 45 cm until your child reaches 105 cm in height. 

With it’s streamlined, space-saving size, the Sirona Q can be quickly and easily installed into smaller cars, but thanks to its intelligent design there is plenty of leg room left for comfort. It also features a one-hand reclining function to get that position perfect on the go. 

While it can be safely used in a rearward-facing position for up to 4 years, the Sirona Q i-Size is also able to be used as a forward-facing car seat once your child reaches 16 months or 76 cm height, if preferred. The smart, 360° rotation system makes it easy to switch between these positions, and also allows the car seat to be swivelled to the door side of your vehicle, making it easy to get your child in and out of the car without putting strain your back.

One-click ISOFIX installation makes fixing your Sirona Q to your vehicle seat quicker and easier than ever while offering increased safety. The advanced anchoring technology prevents any risk of incorrect installation, ensuring the seat is correctly positioned for maximum protection. The unique Seat-to-Chassis technology also enables a direct connection between the seat and the chassis. This means that in the case of an accident, the force of impact transfers straight to the chassis, in turn activating the safety features of the car and the seat, thereby minimising the force of the accident as quickly as possible for the greatest protection.

Another Sirona Q feature to shout about is the integrated Adjustable Impact Shield with leading-edge A.R.T Technology. This remarkable system works similarly to an inflated airbag, absorbing the force of impact in the forward-facing position and reducing the risk of serious neck injuries substantially compared to the conventional 5-point harness. A.R.T Technology also ensures that your child is properly secured within the safety zone of the seat. The Sirona Q also has an innovative Linear Side-impact Protection (L.S.P) System which combines with the energy-absorbing inner shell of the car seat to significantly increase your child’s safety in the case of a side-on collision, reducing the force by approximately 25%.

Able to fit with the Z Base system, the Sirona Q makes the perfect follow-on from the Cloud Z as part of the Z-line family, providing a complete from birth to 4-year system. The Sirona Q also comes with a special inlay to prevent your baby’s head from tipping forward while they sleep. This can be removed once your child grows taller than 60cm, to offer them extra space.
