A floor is the bottom surface of a room or vehicle. Floors vary from simple dirt in a cave to many layered surfaces made with modern technology. Floors may be stone, wood, bamboo, metal or any other material that can support the expected load.
Floors may incorporate glass, mosaic or other artistic expression, like this little mosaic from the Rietberg Museum (Zürich, Switzerland)
