Cotton sheets are a classic choice, known for their breathability and durability. Cotton sheets come in a variety of thread counts, with options ranging from crisp percale to silky satin weaves.
Traditionally, jersey was primarily made with wool but is now commonly made with wool, cotton, and polyester. Jersey is generally knit with a plain stitch on a single set of needles, with all the loops facing the same direction.
A bed sheet is a rectangular piece of cloth used either singly or in a pair as bedding, which is larger in length and width than a mattress, and which is placed immediately above a mattress or bed, but below blankets and other bedding (such as comforters and bedspreads). A bottom sheet is laid above the mattress, and may be either a flat sheet or a fitted sheet (a sheet which has been sewn with elastic or a drawstring along the hem of the top, sides and bottom of the sheet to prevent it from slipping off of the mattress). A top sheet, in the many countries where they are used, is a flat sheet, which is placed above a bottom sheet and below other bedding.
