A simple and modern tension-mounted shelving unit, made in Switzerland around 1955. It is tension-mounted between floor and ceiling, consisting of two perforated steel uprights with a matte black finish and five boat-shaped solid birch shelves with a clear lacquer finish. A steel rod is inserted through the holes in the uprights, supporting the shelves on either side. The bottom of the uprights is reinforced with a smaller diameter tube to accommodate ceiling heights of 220–330 cm. The minimalist design utilizes beautiful, natural materials. It can be used as a wall shelf or a room divider.
