This invention comprises compoundable units adapted to be tiered for making display arrangements for cylindrical bottles of various sizes, and facilitating the disposition of the bottles in either a horizontal or an inclined position with their necks pointing either upwards or downwards. Each unit has one or more horizontal elements therein, comprising frame members defining planes or shelves in the centers of which there are formed openings of an appropriate profile. Each opening includes polygonally-shaped portions which are symmetrically positioned along the major axes of each of the shelves. Said units are adapted to be alternatively positioned into nested relationship for packaging and/or storage.
