Bed sheet

A bed sheet is a rectangular piece of cloth used as bedding, being placed immediately below or above bed occupants. Bed sheets can generally be divided into two categories: "top" and "bottom" sheets. A bottom sheet is laid above the mattress and bed occupants lie on it. It may be either a flat sheet (extra fabric is usually tucked under the mattress), or a fitted sheet, which is sewn in a pocket-like shape to go down over the corners of the mattress, and has an elastic band around the edges of the sheet to prevent the sheet from slipping.
