Does anyone actually sit in the chair between the workstations? There seems to be no reason at all to do so.
I have a suggestion for that. When you walk into that alcove and look at any of the stations, you automatically 'sit down' in it and moving around while there has you wheeling about (with the appropriate wheel rattle and squeaking/creaking sfx of course), though under the hood all that's otherwise happening is hiding the chair and lowering the player camera a bit. You move slower, except for sprinting (or jumping) which will be at full speed and disable sitting down for a few seconds (it's obviously not the time to ascend the cosmic throne). Also, at half stamina and below you have a small chance of falling asleep while not actively interacting with any of the stations: you'll know it's happening by your view starting to drift down at an accelerating rate (you sleep when the view hits looking straight down - the starting speed being determined by how bad your stamina is), and you can avert it by sharply looking upwards. Though sleeping there only recovers stamina at half the usual rate, to keep the bedroll's value up.
Turning around and moving towards the exit of the alcove has you stand back up. And a funny bit because why not: rolling backwards out of the alcove causes the chair to catch on the edge and ungracefully toss you across the floor. That could make for a good ariral prank too, them sneaking in and suddenly dragging the chair backwards. Which leads into another funny moment if you turn around quickly enough when you hear footsteps: they'll stand still to avoid notice and wait for you to turn back around... or, if you stare at them, awkwardly and slowly walk backwards, open the door, and close it behind them (-rep for being a spoilsport).
