Advanced Safety for Everyday Family Travel

Safety is the most important reason to choose a high-quality child car seat, and the Sirona G3 Plus has been engineered with this priority at its core. The seat complies with the UN R129/04 regulation, which reflects modern European safety requirements and includes side-impact testing, height-based classification and strict installation standards.

The protective shell, integrated safety systems and stable base connection work together to create a secure travel environment. When installed correctly on Base G or Base G3, the seat is connected to the vehicle through ISOFIX connectors and a load leg, helping reduce installation errors and improve stability during travel.

For parents, this means greater confidence during daily journeys, school runs, weekend trips and longer family travel.

Rear-Facing Travel for Higher Protection

One of the key safety advantages of the Cybex Sirona G3 Plus is extended rear-facing travel. For young children, rear-facing positioning helps protect the head, neck and spine more effectively during frontal impact situations. Instead of the child’s body being pulled forward by crash forces, the seat shell absorbs and distributes the energy across a wider area.

Children must travel rear-facing until at least 15 months, but the Sirona G3 Plus allows rear-facing use up to 105 cm. This gives parents the option to keep their child in the safer rear-facing position for longer, which is especially important during the early years of physical development.

360° Rotation for Easier Boarding

The 360° rotation mechanism makes daily use much more comfortable. The seat can be turned towards the vehicle door, allowing parents to place the child into the seat, adjust the harness and check the position without awkward bending or twisting.

This function is particularly valuable when the seat is used several times a day. It makes boarding quicker, reduces strain on the parent’s back and helps ensure the harness is positioned correctly before every journey. The rotation works even when the seat is reclined, making it practical for sleeping children and longer trips.

Advanced Linear Side-impact Protection

Side-impact collisions require specialised protection because the distance between the child and the impact point is limited. The Sirona G3 Plus features Advanced Linear Side-impact Protection, which works with the energy-absorbing shell and specially designed headrest to help reduce the forces transferred to the child in a side collision.

The L.S.P. elements are designed for real-life usability and can be folded away when space in the vehicle is limited. For best protection, the side nearest the vehicle door should remain activated whenever possible.

Comfortable Ergonomic Position

The Cybex Sirona G3 Plus is designed to support a natural and ergonomic sitting position. The seat helps keep the child’s legs and hips in a posture-friendly M-position, supporting comfort and healthy development during travel. This thoughtful geometry is especially important for young children, who may spend significant time in the seat during daily routines and longer journeys.

The adjustable headrest allows the seat to grow with the child, helping maintain correct support for the head, neck and shoulders. As children develop, proper headrest adjustment is essential for both safety and comfort.

Five Recline Positions

The seat offers five recline positions in both rear-facing and forward-facing directions. This allows parents to choose the most comfortable angle for the child depending on the situation. A more upright position is useful when the child is awake and observing the world, while a deeper recline supports rest and sleep during longer journeys.

Easy recline adjustment makes the Sirona G3 Plus practical for everyday use. Whether travelling across the city or taking a long road trip, parents can adapt the seat to the child’s needs without unnecessary effort.

All-Round Air Ventilation and Plus Fabrics

The Sirona G3 Plus is designed to keep children comfortable in different weather conditions. Carefully placed ventilation holes promote airflow around the seat, helping reduce heat build-up during warm days or longer journeys.

The Plus version adds specially developed mesh fabrics that are significantly more breathable than conventional car seat covers. This makes the seat especially suitable for families who travel often, live in warmer climates or want extra comfort during summer months.

Base G and Base G3 Compatibility

The Sirona G3 Plus is part of the Cybex Modular G3 system. It is compatible with Base G and Base G3 (the base is purchased additionally), allowing families to use one base concept across compatible CYBEX baby and toddler car seats. This modular approach is practical for parents who want a structured car seat system for the first years of life.

The base is installed using ISOFIX connectors and a load leg. Correct installation is essential, so parents should always follow the user guide and check visual indicators before travel. The secure click-on installation helps simplify daily use while maintaining a stable connection in the vehicle.

Materials and Everyday Durability

Cybex Gold products are known for combining modern engineering with refined design and practical materials. The Cybex Sirona G3 Plus uses durable upholstery designed for daily family life, regular journeys and seasonal changes. The seat covers are machine washable at 30°C, making maintenance easier for parents.

The Plus fabric line gives the car seat a more premium and breathable feel while maintaining the strength needed for years of use. The Moon Black finish creates a clean, sophisticated appearance that fits easily into modern car interiors.

Use Throughout the Year

During spring and summer, the ventilation system and breathable Plus fabrics help create a more comfortable internal climate. Parents should still control the car temperature, avoid overheating and choose appropriate clothing, but the seat’s airflow design provides an important comfort advantage.

During autumn and winter, the seat remains practical for everyday travel. Thick coats should not be worn under the harness because they can prevent the straps from fitting tightly against the body. A safer approach is to dress the child in thinner layers and place a blanket over the secured harness if additional warmth is needed.

Who Is the Cybex Sirona G3 Plus For?

The Sirona G3 Plus is suitable for families looking for a premium toddler car seat with advanced safety features, smooth rotation and long-term comfort. It is especially practical for parents who use the car daily and want easier access when placing the child into the seat.

This model is a strong choice for parents who value rear-facing travel, i-Size certification, ISOFIX base installation, breathable fabrics and a design that grows with the child up to approximately four years old.
