Kinderkraft ONETO3 i-Size
The Kinderkraft ONETO3 i-Size works from when your child reaches 76 cm up to 150 cm — what we traditionally called groups 1, 2 and 3. It fully meets the R129 i-Size standard.
Fitting is quite intuitive thanks to ISOFIX. Remember that for the smallest children the TOP TETHER strap is required as a third anchor point. Once installed, it’s comfortable for child and adult alike: it reclines into 5 positions with one hand — essential for when your child falls asleep and their head tips forward. The Easy Grow system adjusts the headrest across up to 18 heights and the harness at the same time, with no need to re-thread at every growth spurt. And the Side Protect System (SPS) adds side reinforcements that absorb energy on impact, protecting the shoulders and hips.
It suits families who don’t want to swap seats every few years. We especially like how they handled the child’s growth through the headrest height: where other models are fiddly, here the mechanism is simple. Like any ISOFIX seat, it’s not the handiest for constantly switching cars — but as a main seat, it offers a sturdiness and side protection that won us over.
