A bedsheet is a rectangular piece of cloth that is typically used to cover a mattress. It is usually made of cotton, linen, or a blend of different materials, and comes in various sizes and designs to fit different bed sizes and personal preferences. Bedsheets serve several purposes, including providing a comfortable sleeping surface, protecting the mattress from dirt and wear, and adding aesthetic appeal to the bedroom decor. They can also be easily removed and washed to maintain hygiene and cleanliness.
