Abstract

Abstract In a multi-tier tower for goods display, at least two platforms (10) arranged one above the other are detachably connected with one another by a plurality of spacing supports (12). Along a forward edge (16) of a base plate (14) of the respective platforms there is provided a first wall (18) directed substantially downwards therefrom and along a second edge (21) of the base plate (14) there is provided a second wall (22) directed substantially upwards. The base plate (14) is inclined downwards from the first edge to the second edge.
