The Cybex Sirona Gi i-Size is the ideal choice for parents seeking safety, comfort, and ease of use for their baby.

Key Features
Safe rear-facing travel. The Cybex Sirona Gi i-Size allows rear-facing travel up to 20 kg or 105 cm in height. This position is up to 73% safer as it distributes forces in case of a collision, protecting the neck, head, and spine.
360-degree rotation. This system makes it easy to place and remove the child from the car door, avoiding unnecessary effort and enabling quick adjustments. It is perfect for parents looking for daily convenience.
Suitable from birth. With the optional newborn insert, it can be used from 40 cm in height. Without the insert, it is suitable from 61 cm and accompanies the child up to 105 cm.
Reclining and comfort system. Offers five reclining positions to ensure maximum comfort on short or long trips, adapting to the baby’s needs at every stage.
Side-impact protection. Incorporates a linear protection system that minimizes force in case of side impacts.
Enhanced breathability. The integrated ventilation system ensures constant airflow, keeping the child cool even on hot days. The Plus version offers mesh fabric that significantly improves breathability.
Forward-facing option. While not recommended, the seat allows forward-facing orientation from 15 months and 76 cm in height. However, the safest option is to maintain the rear-facing position for as long as possible.
Easy to clean. The covers are removable and machine washable at 30°C, making it easy to keep the seat in perfect condition.
