I still have not quite understood to what extent working on the floor is good for the body. If one were only to be sitting in seiza that would not be a problem as it actually helps you keeping your back straight. But what about moving, bending, reaching for objects and all the other usual movements we do in a workplace? I find that working on the floor forces my back into painful and not always useful postures. I must admit I have some problems with my lower back, which gets easily tired, and I wonder whether seiza will eventually help me correcting my posture or actually increase the stress on my lower back…
