Cybex Sirona S i-Size

Safe. Simple. Swivel 

The Cybex Sirona S i-Size car seat is full of features to keep both child and parent happy for longer. This i-size seat offers state of the art safety features that provide all round protection and allows you to rear face your little one up to 4 years. Not only is it one of the safest seats on the market, but one of the most accessible too, thanks to the introduction of the 360 swivel feature, allowing for easy entry and exit of the seat.

Rear Face for Longer

The Cybex Sirona S i-Size is suitable from birth to 105cm and can remain rear-facing throughout this time. Rear Facing is proven to be the safest direction of travel in the event of a head on collision. Optionally, you can forward face the seat from 76cm and 16 months. The Driving Direction Control (DDC) prevents misuse by only allowing forward facing when your child meets these requirements. 

360 Rotation

The swivel capabilities of the Sirona S not only allow you to switch between forward and rear facing with ease, but allow you to stop in between too. Eradicating the backache of awkwardly reaching over to lift your child in and out of the seat and fiddle with the buckle, you can now simple rotate the Sirona S to face the door and your little one can be placed in, or even climb in at an older age. 

All Round Safety

The innovative ER Tech reduces the forces exerted on the neck in the event of a head on collision by 20%. The headrest slides down, progressively limiting the neck’s exposure to the impact forces, and subsequently locks into position. The Linear Side Impact Protection features retractable side panels that exert energy away from the seat in the event of a side on collision. Teamed with energy absorbing materials, a padded inlay and cosy headrest, the Sirona gives unbeatable protection. The headrest adjusts to 12 positions, giving you peace of mind that your child is always receiving the optimum fit and comfort as they grow. 

ISOFIX Stability

The Sirona S i-Size is complete with an integrated ISOFIX base, offering the utmost stability in your vehicle. Install the seat using the ISOFIX connectors and stabilise using the extendable support leg, which helps to reduce forward rotation of the seat. The base gives interactive feedback to ensure it is fitted correctly to avoid error. The integrated base allows for not only the 360 swivel feature, but also multiple recline positions in both facing modes. 

Added Extras

Not forgetting the little features that make a big difference. The 3 point harness features a buckle holder to make buckling up a breeze. The high quality materials not only provide comfort but are removable and washable too.
