Description

NOTE: The base is not included, it is sold separately.

Meet rear-facing travel made simple with the CYBEX Sirona G3 car seat, offering up to 50% higher safety levels* for your child.

Its 360° rotation makes getting your child in and out far easier by positioning them at a much more manageable angle. Specially designed to provide an ergonomic sitting position throughout, it keeps your child’s legs and hips in the posture-friendly M-position to aid their
development as they grow.

The advanced Linear Side-Impact Protection System adds 25% more protection in a side collision**. As part of the Modular G3 family, Base G3 used for the Cloud G3 fits this seat perfectly, providing a secure solution for the first four years.

UP TO 50% HIGHER SAFETY LEVELS*

Children must travel rear-facing until they are 15 months old and the Sirona G3 delivers up to 50% better protection until they are 4 years*. In a frontal collision, the seat’s padded shell absorbs and distributes the impact while holding the child close, limiting motion and reducing strain on their neck.

EASY ON AND OFF-BOARDING

A 360° rotation mechanism makes it so easy to get your child in just the right position to get them in or out of the car, even when reclined, making it much quicker and better for your back.

25% MORE SIDE PROTECTION**

The advanced Linear Side-impact Protection combined with an energy-absorbing shell and a specially designed headrest gives your child 25% more protection in a side collision2 keeping them safer on every trip. Advanced means it opens automatically when take out of the box, one less thing to worry about. It can easily be folded away when space is limited.

MODULAR SYSTEM

As part of the Modular G3 family, both the Cloud G3 and Sirona G3 fit Base G3 and Base G.
Once your child has outgrown the infant car seat, the Sirona G3 can simply be installed with just one click. Thanks to ISOFIX connectors, it provides a user-friendly, safe foundation for the first 4 years.

ISOFIX AND LOAD LEG

Extra stability and safety in the car, with a load leg to prevent forward rotation in the event of an accident and user-friendly ISOFIX fastenings that connect a separately purchased base directly onto the chassis of your car.

DOUBLE NEWBORN INLAY ACCESSORY***

Two cleverly designed, removable inlays let you use the car seat from day one. The first,
newborn inlay is for babies measuring 40 to 60cm. It sits underneath a soft, secondary inlay to keep their legs in a posture-friendly M position to support spine and hip development as they grow.

BELT HOLDERS

Cleverly designed belt holders keep the harness straps out of the way to avoid your child accidentally sitting on them when putting them in the car seat, making the whole process so much smoother and simpler for parents.

MULTIPLE RECLINE POSITIONS

Always find the perfect traveling position as your child grows. 5 different recline levels, in both front and rear-facing positions are specially designed to provide a comfortable, ergonomic position for those welcome mid-trip naps or on longer journeys.
