Rear-facing is one of the safest ways to travel. In the critical first moments of a front impact, the child's body is pushed against the padded car seat shell, minimizing movement and reducing the force acting on the child's neck. Mandatory up to 15 months (76 cm), we recommend keeping your child rear-facing for as long as possible. The Sirona Gi i-Size is designed for comfortable rear-facing travel until your child weighs 20 kg.​ (*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2022 ADAC frontal crash test criteria.) All-round air ventilation lets air flow through channels in the car seat, carrying away heat and helping avoid a sweaty ride for your little one. The Plus version also includes mesh fabric that increases breathability up to six times compared to regular fabrics.
