> sleeping on the couch for 8 months rather than 8 days.

Wonder what that actually translates to, in space

Is there an extra "guest" specially-adapted "zero gravity sleeping bag" or such?

All I read was that the "couch" is a sleeping bag in the Japanese module. I think the real sleeping quarters provide privacy as well as strapping down the occupant as some semblance of gravity.
