A picture showing the chair out of the way and the keyboard tray pivoted off to the side and back. I wouldn't have even tried the office thing unless I could move around comfortably without bumping into stuff. It's very comfortable, not cramped at all.
You can see a 2x4 up against the bottom of the curved wall. This is a kick board to keep me from accidentally stepping there and taking a chance on breaking something. It also stops the chair wheels thank goodness.
