Abstract: A piece of furniture possibly provided with shelves and usable for the storage of various goods. This piece of furniture comprises at least one storage unit consisting of an upper tray and a lower tray both secured at right angles to a vertical support element, which forms either a part of the door or the door itself of the furniture frame; the storage unit being pivotally mounted on bottom and top wall portions of the frame, respectively, at location areas which are decentralized with respect to the axis of the frame; the trays having a peripheral edge so irregularly curved as to enable the furniture doors to be swung about the decentralized location areas without any shock between two adjacent storage pivoting units.
