The frame has four rails which are interconnected to form a rectangular shape. The frame includes at least two, preferably four, detachably interconnected sections. The rails may be made of ethyl vinyl acetate. Alternatively, each of the rails has a tubular foam body and a rigid central rod fitted within the tubular foam body. In one embodiment, the frame includes four rails, four corner elements and four coupling units interconnecting the rails and the corner elements.
