Starfleet believes that providing comfortable living quarters to all crew and attached personnel to be of primary importance. Indeed, living accommodations are one of the most visible displays of Starfleet's commitment to caring for its single most important "system", its people.
These accommodations typically include a bedroom, living/work area, and a small bathroom. Living quarters decks are designed to be modular with movable walls to permit reconfiguration for requests as crew load and structure change. Other amenities available include food synthesizer terminals (replicators), a sonic shower and standard showers, null-grav sleeping chambers, and personal holographic viewers.
Individuals assigned to a starship for more than six months are permitted to reconfigure their quarters within hardware, mass and volume limits. Individuals assigned for shorter periods are generally restricted to standard quarters configurations.
