Product details
From everyday errands to longer family journeys, the Kinderkraft ONETO3 i-Size Car Seat offers adaptable comfort as your child grows. Designed for children 76–150 cm tall, this forward-facing seat combines practical adjustments with thoughtful protection.
🛡️ Protection for growing passengers
ONETO3 i-Size meets the R129 i-Size standard. Its SIDE PROTECT SYSTEM provides reinforced side protection, while the three-layer H-GUARD headrest with memory foam helps absorb impact energy around the head and neck.
✨ A fit that grows with your child
The EASY GROW SYSTEM lets you adjust the headrest and internal harness together using one hand. With 18 headrest positions and a removable insert for smaller passengers, it is easy to adapt the seat to your child’s height.
🚗 Practical installation
ISOFIX connectors make installation straightforward. When travelling with younger children in harnessed mode, the TOP TETHER strap must also be used. Both systems have indicators to help check correct installation. Older children may use the appropriate belt-secured configuration without ISOFIX, following the manufacturer’s instructions.
