The tower-shaped shelving elements (4,4a) taper upwards and have further shelf elements (4b) built onto side parts (2a-2e) along a sloping surface. At least two tower-shaped shelving elements are positioned next to each other to form an upward widening intermediate space. Further shelf elements (4b) are incorporated in the intermediate space to form a cohesive shelving wall. The further shelf elements are each formed of a tower-shaped shelf element tilted by 180 degrees. The tower shaped shelf elements are formed of superimposed stepped elements (1a-1e) with a bridge shape with two vertical side parts (2) joined at the top by a cross piece (3).
