Sivu is a foldable table lamp inspired by the motion of opening and closing a book. The simple and layered structure makes the lamp ecological to produce. The construction consists of two parts, which are connected with an artificial leather strip. This makes the construction flexible and adjustable. A led strip is implemented inside the walnut core, which passes through the construction. Plexiglass softens the light and the illuminated area can be easily adjusted by opening and closing the light.
