fitted sheet
A fitted sheet is a type of bed linen designed to cover a mattress snugly. It has elastic corners that help it stay in place, preventing it from slipping off while you sleep. Fitted sheets come in various sizes, such as twin, full, queen, and king, to fit different mattress dimensions.
Typically made from materials like cotton, polyester, or a blend, fitted sheets provide a smooth surface for comfort. They are often used in combination with a flat sheet and pillowcases to create a complete bedding set. Fitted sheets are easy to put on and take off for washing.
