Abstract: An adjustable bed skirt includes a deck with a peripheral edge around its perimeter, and a ruffle attached around the perimeter of the deck at the peripheral edge. The deck includes a releasable longitudinal fold and a releasable lateral fold, reversibly secured by closure members. The ruffle includes a plurality of releasably extendible pleats. Each of the longitudinal and lateral folds extends into an associated one of the pleats. When the longitudinal fold is released, the deck and the ruffle are changed from a first, folded width to a second, unfolded width. When the lateral fold is released, the deck and the ruffle are changed from a first, folded length to a second, unfolded length.
