I think I have a decent computer Ikea desk (one with keyboard drawer which pulls out under the main desk surface) and swivel chair with arm rests. I am studying a bunch of software with books; so, I put it on the desk to read it while practicing with my Mac on this desk. For some reasons, my neck areas get stiff. So, I think my seating position is not good. How do you sit at your desk for prolonged time? When I am at my desk at home, I usually go at it for hours no end.
