Ive been playing (and suffering) for years on my lousy computer chair and i think its time i did something about it . Should I get a specific guitar chair? wedge cushions? I heard wedge cushions are good cause they force you to lean forward thus relieving the stress on your back. I already have a footstool, but my computer chair is definitely not helping me at all . Thanks in advance guys P.S. I didnt know where to post this. If this is in the wrong section, I apologize in advance and ask for it to be moved to the appropriate section. Thanks again everyone.
