Abstract: A decorative bed ruffle is capable of installation on a mattress foundation such as a box spring without removal of an upper mattress therefrom. A band of elastically stretchable material forms a closed loop adapted to be stretched to pass over the upper mattress and grippingly retained on the sides of the mattress foundation. The width of the band is such-that top and bottom edge portions of the band will extend over and elastically grip top and bottom edge 5 of the mattress foundation, respectively. A decorative skirt is attached to the band of material in overlapping relation therewith, for covering at least part of a central portion of the band extending over the foundation sidewalls, and at least part of the space between the mattress foundation and a supporting floor surface.
