Sitting in a chair speeds up the rate in which you recover from a Fracture and the rate in which you recover yellow bile.
Maybe Outdated Warning?
WARNING : Chairs seem to retain any logged off occupants, and moving an unknown chair onto your claim may allow unwanted visitors to log back on in your base.
A character that logs out on a chair, or any object that you can sit on, will log into that object even if its moved, as long as it is a valid location for a character to be. If the object is currently being lifted, is in a sled/leanto, or has been destroyed the character will log into the location that the object was in when it logged out.
