I play fake drums in Rock Band and have a great time with it. Problem is, my dining room chairs aren't great for drumming. They're a little low and generally bulky compared to what I need when I'm rocking out. I ended up finding the "Vitamin" stool at Ikea and it's perfect.
- Adjustable height.
- Comfortable seat.
- Tolerant of the need to lean forward or backward (at least if you're playing on carpet) - underneath the bottom is sort of angled on the edges.
Plus, it's pretty reasonably priced. If you're looking for a good drummer stool, grab yourself one of these.
