A super single bed is 48 inches wide and 84 inches long. These beds accommodate most adults comfortably and can be used in small bedrooms, hotel rooms and dorms.
Most super single beds are water beds, although some are cots that fold up and can be moved from one room to another. They are also used as the bottom bunk in some bunk beds that have a regular-size single mattress on top.
Bedding for super single beds can be found online. Most department stores only carry a small amount of super single sheets, mattress pads and comforters, if any at all.
