> But I'm afraid that the best desk height for preventing tension is going to be around where my knees end up. I have to respectfully disagree. Unless your elbows are level with the tops of your legs, when seated, then this will not be the case. Most desks are only something like 3/4" thick (that's the thickness of mine), and you will almost certainly have at least that much of a gap. If you don't, make sure you're sitting up straight. > I can't say I've ever seen a chair with arm rests that low. Get one without armrests, or take them off. On my chair they're adjustable, and the lower setting is approximately level with the top of my hip bone. However, that is a couple of inches too short. Again, ensure you are sitting up straight (and get your shoulders rolled back, if you slouch). Proper posture is by far the most important part of this whole equation--coming from someone with piss-poor posture! I have this chair, and taking the arms off would take me, I think, under a minute: https://www.amazon.com/gp/product/B000Q5XTE8/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B000Q5XTE8/ref=oh_aui_sear...
