Cybex Sirona G3 car seat 61-105cm

A rear-facing car seat designed for protection, the Sirona G3 car seat delivers 50% higher safety than a conventional forward-facing seat (based on internal testing). 360° rotation makes getting your child in and out easy. 

360° Comfort & Safety

Rear-facing travel made simple. The CYBEX Sirona G3 car seat delivers up to 50% higher safety levels for your child compared to a conventional forward-facing seat (based on internal testing). 360° rotation makes getting your child in and out easier by positioning them at a much more manageable angle. Specially designed to provide an ergonomic sitting position, the car seat keeps your child’s legs and hips in the posture-friendly M-position, aiding their development as they grow. Activating the advanced Linear Side-Impact Protection System adds 25% more protection in a side collision (based on internal testing). And as a member of the Modular G3 family, the Sirona G3 fits onto the same base unit as the Cloud G3 infant car seat, part of a secure solution for the first four years.

Highlights & Features

Up to 50% Higher Safety Levels

Rear-facing car seat

Children must travel in a rear-facing position until they are 15 months old, and ideally up until they are 4. When used rear-facing, the Sirona G3 delivers up to 50% better protection compared to a conventional forward-facing seat (based on internal testing). In a frontal collision, the seat’s padded shell absorbs and distributes impact force while holding the child close, limiting motion and reducing strain on the neck.

Easy On and Off-boarding

360° rotation

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 the car seat is reclined. Much quicker and much better for your back.

25% More Side Protection

Advanced Linear Side-Impact Protection System (L.S.P.)

When activated, 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 collision (based on internal testing). Advanced L.S.P. Systems open automatically when taken out of the box, one less thing to worry about when setting the car seat up. If space is limited in the car it can easily be folded away.

One Base – Two Seats: ​Designed to Cover Your First 4 Years

Modular system

As part of the Modular G3 Family, both the Cloud G3 infant car seat and the Sirona G3 toddler car seat fit the Base G3 and Base G. Once your child has outgrown their Cloud car seat the follow-on car seat Sirona G3 can simply be installed with just one click. Secured by ISOFIX connectors and a load leg, the base provides a user-friendly and safe foundation for the first 4 years.

Guaranteed Comfort & Convenience for All

Multiple recline positions

As your child grows, youll always be able to find the perfect traveling position. 5 different recline levels, in both front and rear-facing directions, are specially designed to provide a comfortable, ergonomic position for mid-trip naps or for relaxation on longer journeys.

Optimal Breathability

All-round air ventilation

Precisely placed ventilation holes provide your child with all-round ventilation, creating a wonderful traveling environment. Plus Line car seats also have specially developed mesh fabric, which is up to six times more breathable than conventional car seat covers, for extra comfort on hot, sweaty journeys.

Grows with Your Child up to 4 Years Old

Ergonomic posture support

Special inlay lets you use the Sirona G3 from birth, while a height-adjustable headrest can also be adapted as your child grows. Certified by the AGR back health organization, this car seat is designed to keep your childs legs in a posture-friendly M-position to support their hip development, providing ergonomic comfort on every journey. 

Straightforward Installation and Anchorage

ISOFIX and load leg

The Sirona G3 fits onto the Base G3, delivering extra stability and safety in the car. A load leg prevents forward rotation in the event of an accident and user-friendly ISOFIX fastenings connect the base securely to the chassis of your car.

Hassle-free Boarding

Belt holders

Thoughtfully designed belt holders keep the harness straps out of the way when youre getting your child in the car seat, making sure they arent accidentally sat on and making the whole process smoother and simpler.

For Use from Birth

Double newborn inlay accessory

Use the Sirona G3 car seat from day one thanks to two removable inlays. The first newborn inlay is for babies measuring 40 to 60 cm. It sits underneath a secondary inlay and helps keep the babys legs in a posture-friendly M-position, supporting spine and hip development as they grow.
