Cotton is the most popular bed sheet fabric in the world. It is affordable, easy to care for, and provides great comfort. There are mainly three types of cotton sheets available in Egyptian cotton, Pima cotton, and upland cotton. Egyptian cotton bed sheets are the rarest whereas upland cotton bed sheets are the cheapest among them and the most popular ones. Upland cotton acquires 90% of the cotton bed sheets that are available in the market. Even two bedsheets made of the same cotton could differ greatly. These bed sheets also vary with their properties like thread count, breathability, wash care, etc.
