Re: Calling All Bad Back Drummers: Ergokinetic Thrones
Sorry, I don't have any experience with the ergo chair you at talking about but years ago when I was in three bands and playing constantly I bought a roc n soc nitro throne. It instantly helped my back and I have used it ever since. The air shock keeps a level height but has a little give to it and the seat is huge but soft and padded. Sounds like you have a serious back issue though, I don't know if a chair alone will do it.
Also, I went through this save a back training a while ago that talked about the importance of keeping a curve in your lower back. it made a tremendous difference in how I sit especially as I have started to tackle double bass drum.
