On design rules in decoration and architecture there is nothing written, we are used to surprise us, but there are things that have no head or foot.
An example of this is the "floating bed" that is only held at one end and flanked by three "walls" of iron bars. As roof the same sky, yes, the views are beautiful. It is part of a hotel called «Million Donkey Hotel» and is located in Prata Sannita, Italy, with which is totally real. The buildings are part of a rehabilitated part of abandoned houses in the town, a project designed to attract tourists and give life to the environment.
Little use I see this bed in winter and autumn, perhaps in spring you can enjoy a nap and can be prefect for summer nights, although mosquitoes will not have mercy.
