@mysteronia "it seems like raising my hips above my knees let me sit straight without my back muscles getting all tense and knotty" - this is what yoga teachers advise for people who can't comfortably sit cross-legged (like me). My guess is it's related to hip flexibility (for me). my legs/knees stick up too much, pushing me backwards a bit, and the my back has to struggle to keep me upright and everything becomes the worst
@steph yeah the difference is out all proportion to how small it a change it seems. my inner statist wants all seats to be redesigned by some kind of global dictat
