Thomann KB-15BM

After 2 months of using the product I have the following view:
1. The product is made entirely from MDF (a mix of sawdust and resin) and not wood. Unfortunately this was not advertised by seller accordingly. For legs which are required for compressed this is ok. For horizontal elements that are required to bend is not the best material for sure.
2. All the joints are done by screws through steel plate corners. After the first 10 minutes during mounting I have tight too much a leg screw. As a result one long perimetral side (between legs) had cracked. Since I am a passionate woodworker and also because I have enough tools/machines/materials in my small shop I was able to replace both long horizontal elements with beech wood elements painted black. This changing was not visible but I have paid 3 hours of working for this.
3. During playing at piano the stool is ?screaming? a lot. I suppose that all the MDF elements in pressure-contact without carpentry joining are responsible for this sound. This is very annoying for a piano player.
4. Also the internal double screw mechanical system used to rise the sitting chair is not very tight so I have a gap in gears of few mils when I raised the chair. This is visible when you sit on the chair and you change your ?center of gravity?. You?ll hear immediately this gap.

As a conclusion: the product is cheap and suitable for a beginner or a child. My plans is to keep the seat/the mechanic as a next project in my shop.

I am an non-professional intermediate level piano player. I use a Yamaha P-125 digital piano and the matte paint finish of the stool matches well with the piano.
The stool is very easy to assemble and the height adjustment mechanism worked pretty smoothly. After assembly I realized that all the legs wouldn't touch the floor at the same time causing the stool to rock slightly. But that problem fixed itself when I was seated on the stool; it would slightly stretch and all the legs touched the floor. The cushion is comfortable to sit on (but it is a lint and dust magnet). One of the corners of the frame which holds the cushion was not properly aligned and has a very small gap, not that it was a big problem, but clearly a lapse in craftsmanship.
Overall it is a decent piano stool for a beginner-intermediate level piano player and it does its job pretty well. But maybe not recommended for a discerning professional.

First and foremost, the build quality of this piano bench is exceptional. The sturdy construction ensures stability and durability, allowing me to focus solely on my performance without any distractions. The padded seat provides excellent support, allowing for long practice sessions or performances without any discomfort.

One of the standout features of this piano bench is its adjustable height mechanism. With a smooth and effortless adjustment process, I was able to find the perfect height to achieve optimal posture and hand positioning while playing. This greatly enhanced my playing experience and helped prevent any unnecessary strain or fatigue

Great value for the money. The padding is good enough to sit at least an hour playing, but had some minor defects along one of the edges. You can lift that part up and turn it in the other direction to make it less obvous. Assembly was quite easy but the included IKEA-like wrench could be better. One top is to not overtighten it, then gently sit down on it so that the weight is distributed evenly, then go back to tighten the legs. That way you won't have one odd leg make it unbalanced

If using on hardwood floor I strongly recommend placing felt feet (the adhesive ones they actually sell at IKEA) under the rubber feet. Otherwise the legs will "jump" when your body is pushing the stool back and forth instead of firmly slide, and the sound it made had me worried it would damage the floor. Note: I'm 85kg, might be better if you're smaller.

All in all: Well worth it.
