We first reported on the Sleepbox concept back in '09, and now it's finally become a reality. The Sleepbox, designed by Russian architecture and design firm Arch Group, is a rental sleeping chamber designed to populate airports and other transportation hubs in lieu of proper hotel rooms. Moscow's Sheremetyevo International Airport has installed some trial units, of a "hostel edition" design that differs from the original we posted on.
The rather bare-bones "hostel edition" sleeps two in a bunkbed configuration, has its own ventilation system and provides power and lighting, but lacks the wi-fi, internal vending machine and alarm clock of the standard unit.
We especially like the video that Arch Group has provided of that standard unit, which does a good job of visually and silently revealing all of its features without the bother of having to translate text or voice into different languages:
