For 40€, its nothing to be expected, okay build quality, the lower part of the throne is pretty well built, but the upper half, where you sit on, is not that great.
There's not alot of cushioning on the seat, when you sit on it, all the air from the cushioning comes out by some tiny holes that are on the side of the seat. After 5 minutes of playing, it just feels like your sitting on a wood seat, because there's not alot of cushioning.
I put my throne up pretty high, there is one part of the throne where you can attach the seat with the throne, there's only one part that is gonna keep the seat from tilting, but it doesn't to a great job. After I turned it on tight, so the seat doesn't get flimsy, after a little bit of playing, the bolt that held it tight, went loose.
So when you play for 10 mins, you have to turn the bolt tight again, due to it getting unstable and loose again.
If you look at the different types of drum thrones that are available on the market, this throne is one of the cheapest of them all.
If you're are looking for a good drum throne, I would suggest you to buy a throne, that costs over 60-70€
If you're looking for the CHEAPEST drum throne, this would be it. But beaware of the cons of this drum throne, they can get pretty annoying after long time use.
