I've tried two different spaces: the living room (which has two small tables that are almost regular table height) and the lounge-y chair in my bedroom area. Neither of them is ideal, but I feel like I should give especially the lounge chair more of a shot, since I don't use that chair very often and I could make it "writing chair" without disrupting any other commonly used space. I take my laptop into the living room all the time, but mostly for teleconference socializing, so that's already got a different new association. But yeah, nothing is quite like that coffee shop.
