Sirona Q i-Size

We at CYBEX strongly recommend that you replace a seat after any kind of accident. This is because tiny hairline cracks, which may not be visible to the naked eye, can appear in the plastic parts of a seat after an accident. These cracks can pose an increased risk to safety.

Please refer to the retailer where you bought your CYBEX seat. They will deal with the matter on your behalf.

You can order replacement parts from a specialist retailer near you. To find a store near you, simply go to the store locator on our website: http://cybex-online.com/de/retailer.html

Thick clothing prevents the harness from lying snugly against the body. This incorrect belt positioning could result in the harness slipping off the shoulder. For this reason, your child should wear everyday clothing. Thick clothing such as winter jackets should be avoided where possible. Once your child has been positioned in the seat, he/she can be covered with an extra blanket for warmth.

No, this seat is not approved for use on an airplane.

The head of a young child is large and heavy in proportion to the rest of their body and their neck is relatively weak. A rear-facing child restraint supports the head and neck and is thought, therefore, to reduce the risk of neck injury. Although this remains a topic for research, European regulators are satisfied that by 15 months, the neck has developed enough strength to withstand the forces in a typical crash. For this reason, 15 months was set as the minimum age for rear-facing. However, many R129 child restraints are approved for longer rear-facing use, for example, by children up to 105 cm (around 4 years).

Relatively tall infants may rest their legs on the rebound bar. Bending the legs at the knee does not affect safety in any way. As long as the child has sufficient legroom we recommend using the seat in a rear-facing position, which exposes the child to less force in the event of a collision.

To provide the best possible protection, the telescopic L.S.P. protector nearest the door should be extended as far as possible. It is designed with two settings. If in the longest setting, the L.S.P. touches the vehicle door, then the first setting must be used instead. When the seat is installed in the middle seat, the linear side-impact protection (L.S.P. System) should not be pulled out.

Yes, side airbags may remain activated when using the baby seat.

The newborn inlay should be used up to a maximum height of 60cm (corresponding to approximately 3 months). As soon as the baby cannot be secured comfortably with the harness system anymore, the inlay should be removed.

The CYBEX Sirona Q i-Size can be used by children up to a maximum height of 105 cm (maximum body weight: 18 kg). Depending on the child’s height, this corresponds to approximately four years of age.

Once your child has reached 16 months of age and height of 76 cm, the Sirona Q i-Size can also be used in a forward-facing position. This is not, however, mandatory. We recommend that children travel in a rear-facing position for as long as possible.

No. The newborn inlay is specifically designed for premature babies and very small newborns and needs to be used from 45 to 60cm. Its purpose is to reduce the size of the seat to ensure these infants receive the best possible protection.

The sophisticated 360° rotating mechanism makes it easy to switch from a rear-facing to the forward-facing position - there is no need to remove and re-install the seat which can be an awkward task and cause back strain. Additionally, this mechanism allows the seat to be turned towards the door, making it easy to take the child in and out of the seat. In concrete terms, this means that the seat can be rotated to the left or right to face the door and can also be used either in a forward- or rear-facing position.

We recommend using the Sirona Q i-Size in a rear-facing position for as long as possible to provide the highest level of safety. As soon as your child no longer has enough legroom in a rear-facing position, the seat can be used together with the impact shield in a forward-facing position. To do so, the harness first has to be tucked away in the seat so that the latter can be released. Subsequently, the seat can simply be rotated and your child can be secured with the impact shield. For further details on converting the seat, please refer to the instructions.

The Sirona Q i-Size is an ISOFIX-only seat and can only be installed in vehicles with ISOFIX anchorage points.

The One-Click ISOFIX system makes it easy to install the seat in either a forward- or a rear-facing position and guarantees increased levels of safety. The integrated supporting leg provides additional stability and absorbs the forces released in a head-on collision. The Sirona Q i-Size can only be installed using the ISOFIX connectors.
