Abstract

Abstract A fitted contour no-iron sheet is provided for mattresses, studio couches and the like, comprised substantially of cotton knitted fabric, having balanced two-way stretch characteristics. The sheet is made from a single piece of fabric, devoid of any separate pieces or elastic additions and is formed after cutting by four simple corner stitches. In addition, a conventional border stitching of the rolled edges of the sheet may be provided. The formed contour sheet will conform to several size mattresses and can be fitted without raising the mattress edges. The sheet of the invention is particularly appropriate for hospital beds because the stretch characteristics eliminates strain on corner construction and the usual failure thereof by the raising and lowering of hospital beds to a variety of positions. Furthermore, the sheet conforms to the mattress in its various raised positions.
