Most the time I'm reclining in a big pile of pillows either in bed or on my rug, because fuck bringing an expensive piece of hardware into a lofted bed nearly six feet in the air. I'm not asking for that kind of trouble. If I'm actually at my desk, one leg is drawn up to my chest so I can rest my head on it while I work.
If I'm in public I sit like a normal person, though usually I have my legs crossed, so that'll switch off every once in a while. Comfort over form every day.
