This is only an anecdote, but my parents replaced our office chair with a kneeling chair when I was a kid to keep me from monopolizing the family computer.
Not only did their plan fail, I found that I could sit for hours in that chair where in other "office" chairs I was highly uncomfortable after 30 min.
Also studies and other's anecdotes are worth a pittance compared to rigorous experimentation on your own part as everyone's body reacts differently. I can't count the number of times my experience has run counter to "accepted wisdom".
