Retractable bed hides in the rafters

Mad Men's Vincent Kartheiser hired designer Funn Roberts to create a bed that retracts into the rafters of his compact home when it's not in use. I wish they showed the mechanism in more detail -- I can't tell if it's using counterweights or motors or some other means to make hoisting the bed easier. I once built a bed-frame that hung on ropes from the crossbeams of the warehouse I was renting; it rocked gently, like a hammock, and I loved it. But I never quite figured out how to retract it into the flies when it wasn't in use.
