Abstract

Abstract A contoured bedsheet readily adaptable to folding and compact packaging which can be directly applied to a mattress without turning it inside-out prior to application. The bedsheet comprising a central rectangular portion, two side panels each of which has a common edge with the central portion, at least one end panel having a common edge with the central portion, and at least two corner sections each of which has a common edge with both a side panel and an end panel. In forming the sheet, the corner sections are inwardly folded and, for each section, the common edge between the section and the end panel is secured to the side panel along a line which extends from the intersection of the common edges of the corner section toward the edge of the side panel at an angle which is greater than 90* and less than 120* from the common edge between the corner section and the end panel.
