. It is this sheet that one typically lies on.
In many areas of the world a second flat bed sheet is laid on top of the sheet covering the mattress. This is known as a “top sheet” and when a top sheet is used, the sheet covering the mattress is known as a “bottom sheet”. One sleeps between the two bed sheets. Blankets, comforters, and other bed covers are then placed on top of the second bed sheet.
Bed sheets come in two main varieties–flat or fitted. A flat bed sheet is simply a rectangular sheet of cloth, while a fitted bed sheet has its four corners, and sometimes two or four sides, fitted with elastic

, to be used only as a bottom sheet. The purpose of a fitted bottom sheet is to keep it from slipping off the mattress while the bed is in use. A particular way of folding and tucking while making the bed, known as “hospital corners,” is sometimes used when the bottom sheet is flat rather than fitted.
Bed sheets were traditionally white, but now various colors and patterns are used. The quality of bed sheets is often conveyed by the thread count – the number of threads per square inch of material. In general, the higher the thread count, the softer the sheet, but the weave and type of thread may affect the “hand” of the material so that a sheet with a lower thread count may actually be softer than one with a higher count.
