It was neat to have beds reduce TW when that was one of the only things worth raising, but what about something curio related? like a small boost to learning speed? (1.1 for worst bed 1.3 for best or something like that?).
Of course that's just one example, just saying in general it would be neat if beds gave some better bonus.
It'd be a bit cooler for the daily ritual to be drink tea->sleep in bed to log off.
