These rooms contain beds for crew members to use. The gallifreyan beds fold up into the wall when not in use. The beds are rectangular, but can be remotely adjusted to flex at any point. About one third of the Sleeping Quarters are large "Master Bedrooms", the rest are regular size. The large sleeping quarters have their own bathrooms. There are at least 18 of the large rooms. A TARDIS has an optional diurnal (day/night) cycle. The duration of these cycles, if enabled, will be derived from the brainwaves of the authorized crew members. The lights are controlled by voice commands. The Laundromat's laundry circuits automatically repair, clean, and iron any clothes left overnight in the sleeping quarters.
