Seating in Sindome is straightforward. If a room has built-in seating it will appear below the description and above the list of room exits, on the same line that characters show up.
One example of this is:
The bar is vacant.
You can 'sit bar'. You can 'stand bar'.
When you are sitting at a seat, your @look_place message is overridden with the message that that seat has when occupied.
