In a world where people appreciate good design everywhere, cool mini hotel rooms are the latest ‘it’ trend. In Tokyo, the  Capsule Inn exemplifies the bare-essentials hotel rooms for brief use, and similar concepts are popping up at airports, train stations and downtowns around the world, replacing and mimicking the “day rooms” already existing at many airports.

Unlike Tokyo’s bed-only cabins where customers climb into a human equivalent of a honeycomb for a night’s rest, Yotel pods at Gatwick and Heathrow airports in London and Schiphol Airport in Amsterdam come in larger and more comfortable formats. These self-contained mini hotel rooms are equipped with a bed, table, HD TV and Wi-Fi.

The fourth Yotel is set to arrive in New York in 2011 with a location opening on 42nd and 10th street boasting 669 luxury rooms and the largest outside terrace in any hotel in New York

Also in Amsterdam, Citizen M has a hotel with 230 mini rooms at Schiphol Airport and a 215-room hotel in Amsterdam City. Citizen M plans to open similar hotels across Europe.

Qbic Hotels has opened two “cheap chic” hotels with mini rooms in the Netherlands: Qbic World Trade Centre Amsterdam and Qbic Maastricht, plus one in Antwerp, Belgium.

Taking the next step in rest and space efficiency, Russia’s Arch Group designed the SleepBox.

Along with an airport version of the rest pod, equipped with the usual, high-tech necessities offered by other companies, Arch Group has also designed an easy-to-relocate version fit for hostels. A small, mobile compartment, 2m (l) x 1.4m (w) x 2.3m (h), SleepBox is made of wood and MDF. SleepBox is meant to “allow very efficient use of available space and, if necessary, a quick change of layout”, making it perfect for hostels where demand and space available often come in conflict with each other. The hostel-specific SleepBox features bunk beds, flip-out tables and sockets for computers or phone chargers and not much else. Yuri Pushkin, Tuija Seipell.
