This piano bench, made of wood, is stable to sit upon and remains silent as one shifts their weight to the left or to the right as is usual when playing a piano or keyboard. That is perfectly satisfactory. Optically, the polished, black lacquer looks very classy and the covering of the seat is adequate. The mechanism functions well -- albeit slowly, requiring a lot of knob turning, perhaps making this bench sub-optimal for shared use where adjusting of the height will be oft undertaken.
