I've recently began to realize that the particular stool that I use is probably contributing to my frequent trips to the chiropractor with out-of-whack hips. I have another that is not too stable so I've been looking for comfortable, AFFORDABLE bass chairs. I've come to realize that there is no such beast, but I'm still looking for something comfortable and not terribly expensive. Any thoughts? I really like the Opus brand which slopes slightly downward in the front and takes the pressure off of the hips but they are expensive and I've heard that the company isn't the best to deal with-they tend to ignore deadlines and deliver when they feel like it. Does anybody have any thoughts on good chairs? I like the downward slope and the fact that these are portable. I can't get one of the $750 chairs with the scaffolding around the bottom for foot rests and stuff.
