What is a fitted sheet?

A fitted sheet is a type of bed sheet that is designed to fit snugly over a mattress. It has elasticized corners that help it stay in place and prevent it from slipping or coming off during sleep. Fitted sheets are typically made of cotton, polyester, or a blend of both materials. They come in a variety of colors, patterns, and sizes to fit different mattress sizes, including twin, full, queen, and king. Fitted sheets are an essential component of a bedding set and are often sold as part of a sheet set that includes pillowcases and a flat sheet. Regularly changing and washing fitted sheets can help maintain a clean and comfortable sleeping environment.
