The Sleepbox is an architectural concept by A. Goryainov and M. Krymov. It's something like a capsule hotel or apartment, but it's mobile:
The main functional element in it is a bed 2x0.6 m., which is equipped with automatic system of change of bed linen. Bed is soft, flexible strip of foamed polymer with the surface of the pulp tissue. Tape is rewound from one shaft to another, changing the bed. If a client wants to sleep in maximum comfort, he can take the normal set of bed linen for an extra fee. SLEEPBOX is equipped with a ventilation system, sound alerts, built-in LCD TV, WiFi, sockets for a laptop, charging phones. Also under the lounges is a place for luggage. After the clients exit, automatic change of bed linen starts and quartz lamps turns on. Payment can be made on a shared terminal, which provides the client with an electronic key. It is possible to buy from 15 minutes to several hours.
