I covered this a while ago, but the concept has finally seen the light of day, check out the sleepbox. It is designed to be a short term hotel room of sorts, allowing travelers to take some time to catch a nap or relax in a clean, comfortable and safe environment.
In mid-August 2011, the first Sleepbox was installed at the Aeroexpress terminal of Sheremetyevo International Airport, Moscow, Russia. It represents the base version made of MDF with a natural ash-tree veneer. This Sleepbox attracted such a great deal of interest from passengers and big companies that chances are first commercially operated boxes will be installed at airports and in the city by the end of this year.
