Our children are happy with zwei'n these chairs - they liked. It is also good that they do not squeak when top setting. But: 1. The shocks are obviously for adults, with far too strong spring. A child of 35 kg can thus only drive up to the chair. An independent adjusting the height is thus not possible. 2. Moving the lumbar support in height is very stiff and thus performed by an adult. 3. "locked" Adjusting the seat depth each other by adjusting the backrest height. In other words: for a young child you need a small seat depth and a low backrest height. If, now, the rest to the lowest level, it comes already at with the greatest seat depth on the seat cushion. Reducing the seat depth (shorter than the seat itself) is not possible. Does an older child, however, the full seat depth, as well as a higher setting of the backrest makes sense. Thus, the adjustment of the seat depth is actually given only on paper. Nevertheless, after a few laps in various furniture stores these chairs are in relation to the otherwise botch offered for a price of about 60 Euri OK.
