Whether ancient or contemporary, the column is a shape always present in the architectonic imagery. Inspired by it, the Cilindro produced by Levira, due to the fact that it articulates in two semi-cylinders, allows one of the halves to be constituted as a container, while the other half, by lifting to a horizontal position the plane that closes it can become a working surface. This surface has on its bottom face a telescopic tubular leg which folds through a small mechanism, allowing the horizontal positioning of the plane that constitutes the work surface.
