This floor lamp is called the "Twiggy" there are a number of retailers who sell this item. It can also be purchased on line, through Ylighting, HiveModern, AllModern, Lumens.... and many more. We love this light, also available in black, white, gray and yellow.. they also have table lamp and wall sconce versions of the design.

By the way, love the dark colors of the furniture here, offset by the vivid red of the lamp and the barstools. Gorgeous!
