Where do you like/prefer coding from?

1. at a sitting desk? 2. at a Standing desk? 3. 1 &/or 2 4. at a dining table 5. on a couch

I, somehow, seem to be more comfortable working on a couch than from any desks. I seem to be able to prolong my state of flow for better durations on it. Does any of you too feel so? or is it just me?
