Bed sheets are pieces of fabric used to cover mattresses, providing comfort and protection. They come in various materials, such as cotton, polyester, and linen, each offering different levels of softness and breathability. Bed sheets typically include a fitted sheet, which has elastic corners to fit snugly over the mattress, and a flat sheet, which lies on top. In addition to comfort, bed sheets play a role in bedroom decor. They are available in numerous colors, patterns, and sizes to match different styles and preferences. Regular washing and maintenance of bed sheets are essential for hygiene and longevity.
