We ought to mention there are alternatives to sitting poorly and standing - sit better. Focus on having a firm, non-rolling chair that you can sit at the front edge of, feet tucked underneath you or flat in front of you. If you don't treat the back of your chair as mould into which you pour your limp spine, sitting won't be as bad for you. And whatever your chair, if you use a lumbar support to correct your passive posture, you'll also be much better off.

Indeed. Kelly actually has a part in the book about this kind of sitting (he favors wooden stools or sitting cross legged or semi cross legged on a chair). Personally I find it more difficult to sit correctly than to stand correctly. But I am quite tall (194 cm / 6' 4'') and about 99% of chairs are too low for me to sit in a good position.
