YAMAHA brand drum throne. The model is the current DS550U. As expected from reliable and trusted Yamaha, this is a very solid model. It's highly stable, and although I haven't used it for a long time, I think the durability is also excellent. There are no issues with use. ★ I had one each for my electronic drum set and electronic piano indoors. This is the second one. This round stool fits well with both electronic pianos and drum sets. There is some degree of use, but I think it's still quite clean. Thank you very much.
