So! I visited a friend recently and happened to sit on this exercise ball chair she had. It was awesome. I felt as though I could sit up straighter, I could feel myself working my core muscles to do so instead of straining my back. Is it crazy to spend $75-80 on one of these things? I mean, when you consider I have to spend $30 per physical therapy session, I guess it isn't much if it helps my back, right? Or am I rationalizing?
Too ugly, though? Will it clash with my highbrow IKEA decor?
