The Cybex Sirona S i-Size Style is a rear-facing car seat for children up to around 4.5 years, finished with a two-tone leather-look trim and breathable mesh that give it a more refined appearance than the Comfort version. It has the same safety strengths that make the Sirona S so highly regarded, including extra side impact protection and a 360° rotation, with added ventilation and sun protection for everyday comfort. It is part of the Cybex Platinum S-Line modular system and is fitted using the Base S.
A Polished Look Inspired by Luxury Car Interiors
The Style version draws its inspiration from the finest car interiors. Two-tone leather-look accents blend with breathable mesh to create a sophisticated, understated finish that suits any car. This design is exclusive to Style colourways, so it is a lovely option if you want your child's seat to look as considered as the rest of your family travel kit. The look is matched by comfort, with the materials chosen to keep your child secure and settled.
Rear-Facing Safety for Up to 4.5 Years
Rear-facing travel is mandatory until 15 months, and the Sirona S lets you continue well beyond that. Its shell acts like a protective shield, spreading impact forces and holding your child close. Cybex reports up to 50% better protection than the same seat used forward-facing in a frontal impact, based on internal testing. Linear Side-Impact Protection adds to this by channelling energy into the energy absorbing shell and headrest, reducing impact forces by up to 25% compared with the same seat without it, also based on internal testing.
Cool, Shaded and Comfortable All Year
The 3D mesh Style fabric regulates moisture on its own and can increase airflow by up to six times compared with conventional materials. Ventilated hard parts add to the effect, helping your child stay cool and dry in every season. The XXL sun canopy offers UPF50+ protection (excluding the mesh parts) and cuts glare for calmer naps. A breathable mesh window improves air circulation, and clever clips let you detach the canopy when you do not need it.
Smooth Rotation and Simple Buckling
On the Base S, the Sirona S rotates a full 360° with one hand, which makes lifting a growing child in and out much easier on your back. A rigid crotch pad helps with positioning, and magnetic belt holders keep the buckle tongues out of the way as you settle your child in. These details take the stress out of busy mornings and quick stops.
Designed to Grow With Your Child
Cybex GrowTech adapts the seat for heights from 61cm to 105cm. The Comfort inlay is included and supports your child until they reach 85cm. For use from birth, the Newborn insert and inlay are available as accessories for babies measuring 40 to 60cm. AGR certified for ergonomics, the seat has an adjustable headrest, a natural M-position and a 40% wider recline range than its predecessor when rear-facing.
