Abstract: A bed linen is provided for positioning on a mattress that serves as a sheet, pillow cover, blanket and bedspread all at the same time. A bottom fabric sheet is provided that has a width much greater than that of a mattress on which it will be disposed so that it drapes over the sides of the mattress like a bedspread. A top fabric sheet is either connected to a central section of the width of the bottom sheet, the top fabric sheet having a width approximately equal (or less) to that of the mattress and connected to the bottom sheet by stitching along all of one side edge, the bottom edge, and the bottom half or more of the second side edge, and unconnected at the top; or the top sheet has a width substantially equal to that of the bottom sheet. A readily releasable connection, preferably a zipper, is provided between the top and bottom sheets to allow access to a sleeping volume between them.
