I'm very short so normal desks are waaay too high for me. I have to crank my professional office chair up to the max. That used to be a big problem because then my legs would dangle and cut off circulation to them and my feet. However, last Christmas my Son got me an 'office ottoman.' It's an under desk footrest and I absolutely LOVE it! My desk is still too high and the depth isn't enough, I can't rest my arm on the desk so my mouse hand gets cold from my wrist laying on the edge. But at least my legs and feet are nice and comfy now. :)
I wish I could find a deeper, lower desk that didn't cost a fortune. They make height adjustable desks, but I can't afford to pay $500-1000 just for a desk. o.O Oh well, I'll live. A little discomfort is worth it to play Sims on my gaming desktop. When I had my toaster of a laptop, I would sit with it on the couch on a cooling pad with my mousepad/mouse on the armrest. Much more comfy, but believe me, I don't miss that old thing one iota!
BTW @Cement I usually have at least one cat on my lap and/or laying on the desk between my keyboard and the monitor while I'm on my computer. The one on my lap cuts off circulation sometimes and the other cat likes to sit up sometimes so then I have to peek around him to see my screen. But, man, they're just too sweet and special, I don't have the heart to push them down. I.just.can't.do.it! lol
