From the manufacturer:
Big Mama is a large floor lamp made out of paper and wood ––basic and eco–friendly Nordic materials – that are used for the shade and the body respectively. Big Mama represents more than simple illumination of space. Big Mama does light up a room, but at the same time it gives the space character and personality. Its shape tells us intuitively more about its function. Simple, direct… with its iconic and super classical shape, there is no doubt this is a lamp. And yet at the same time the strong, dominant and sculptural character of the object resembles that of an item which does not need to possess a mere function in order to justify its existence.
