A device for displaying a sample of sheet material such as carpet or drapery comprises a floor wall having perimetric edges in a polygon shape and a plurality of walls extending upwardly from the perimetric edges thereof. Means are provided for connecting the upstanding walls at the adjoining vertical edges thereof so as to enclose the floor in a box-like configuration having an open upper end. The upstanding walls have mirror surfaces on their inwardly presented sides so that a viewer, looking through the opened upper end will see the illusion that the upper surface of the floor wall extends infinitely.
