This is the Oneto3 i-Size - a safe child car seat that fulfils the latest i-Size standard R129. It is designed for children with a height of 76 to 150 cm (from 15 months to around 12 years). This is the successor to the legendary Oneto3, which has received high ratings from Adac and Öamtc. It is equipped with special safety systems such as the Side Protect System, which provides additional protection in the event of a side impact, and the H-Guard System - a 3-layer, reinforced headrest that protects the child's head and neck in the event of an accident. The child seat also has practical hooks for the harness on the sides, offers the option of hiding the internal harness in the storage compartment and has a comfortable, soft seat that makes the journey easier.
