Abstract: A whatnot has upright posts, crossbeams and shelves, the upright posts being arranged vertically and each upright post is provided with at least one groove extending alongside the upright post and widening in inward direction thereof, wherein the crossbeams are provided at their ends with projections intended to be received by the groove in order to create a connection between the upright posts and the crossbeams, and wherein the shelves are connected to the crossbeams. The crossbeams are positioned in the grooves of the upright posts by shelf supports that are inserted into the upright posts. A stable and easy to dismantle whatnot is achieved by the fact that the shelves are removably connected to the crossbeams by means of dowels.
