Cybex is helping to lead the way in i-Size car seat manufacturing with a series of stunning designs made to keep your child super safe and comply with the stringent R129 i-Size regulations. The stunning new Cybex Sirona Q i-Size Car Seat lets your little one sit rear-facing -the safest way- for longer, up to 105cm (approximately 4 years).

  • i-Size tested to highest safety standards
  • Extended rear-facing for additional safety
  • Side impact protection for additional safety

All about me

Space can be an issue in some cars, which is obviously a challenge for designers. How do you keep an infant seat small enough to fit in most cars but still provide the ultimate in protection and comfort? Luckily, Cybex has risen to the challenge. Its team of German engineers have designed and built an incredible seat which doesn't take up too much space so can be installed in smaller cars, still keeping your little one safe and making it super convenient for you thanks to its 360-degree rotation to make everyday use easier.

Let's talk about that rotation: it's a clever idea to help make life easier for you when getting your child into and out of the seat, simply turn it to face the door, then face it back again. You don't need to take the seat out if you decide to face your little one forward, although your little one can stay rear-facing right until they outgrow the seat. It's suitable for children to rear face from 45cm to 105cm, but from a minimum of 16 months and 76cm in height up to 105cm (approximately 4 years) you can face them forward- it's your choice.

Installing the seat is easy. It can be done in a couple of clicks thanks to its ISOFIX connection. Then all you have to do is extend the front foot prop - this not only helps to keep the seat stable but also helps to absorb forces in the event of a head-on collision, shunting them away from your little one. Indicators let you know when the seat is installed correctly too. With this seat-to-chassis technology, there's a direct link between the seat and the car, so in case of an accident, the force of the impact is transferred straight to the chassis which simultaneously activates the safety features of both the car and the seat and initiates the process of distributing force at the earliest possible stage.

Also helping to keep your little one safe is the telescopic linear side-impact protection (LSP). Whichever direction of travel, the LSP can be individually adjusted to the position of the seat and the type of vehicle it is in. Simply pull it out towards the door that the seat is installed next to and it will help to absorb the force of a side-impact collision at a very early stage. This works in combination with the head and shoulder protectors built into the chassis. And the icing on the cake as far as this seat is concerned is that this is the first i-Size car seat with an adjustable impact shield which features Active Response Technology (ART). In the forward-facing position, the impact shield works kind of like an inflated airbag, absorbing the energy over its entire area, significantly reducing neck strain compared to a conventional 5-point harness. The ART system ensures that your little one is intuitively secured within the safety zone of the seat and the impact shield does not need to be held in place by the vehicle's seatbelt for the first time as it has a new, integrated fastening system.

So that's safety covered, but what about comfort? Well, of course, it's covered with a superb, machine washable cover and is softly padded throughout. The headrest is height adjustable to 12 positions with an integrated harness guide for protection that grows as your child does. The one-hand recline function offers 7 recline positions when rear-facing and 5 positions when facing forwards. A magnetic belt holder keeps the harness out of the way when you're installing your child.

Cybex hasn't forgotten the aesthetics either; there is a choice of 2 types of fabrics - standard and Plus. They both have a harder wearing, two-tone twill-effect fabric around the shell but the Plus also has harder wearing fabrics on the inside of the seat whereas they are softer on the standard version.
