Iconic family of lights, gracing homes all around the world - from its origins in Paris, to New York, to London and beyond. Mantis is instantly recognised for its voluminous, curvaceous shade that emanates a beautiful, wide beam of useful light. The hardware is incredibly minimal and makes the shade float, as if lifted by light and air alone. Functionality and balance at its core, the light is also flexible - you can move the arm around as well as the shade.

From the manufacturers:

As admirer of Alexander Calder, in 1951 Schottlander created the MANTIS series of lamps. Movement is intrinsic to all of Schottlander’s work : an artist, an engineer and in no small measure a handyman, he devised a clever system of counterweights combined with a series of strong and flexible metal bars. The shade also is unique of its kind.
Like an acrobat suspended in midair, it is made from aluminium using spinning and chasing techniques that are a part of the metalworker’s inventory of skills, but to which he has brought his sculptor’s eye to create a helical movement.
