Bed sheets are a type of textile product used to cover a mattress. They are typically made from materials such as cotton, polyester, silk, or flannel, and come in various sizes to fit different mattress sizes. Bed sheets are designed for comfort and softness, and are usually changed and washed regularly. They come in a variety of colors, patterns, and designs, allowing consumers to choose sheets that fit their personal style and preference. In addition to providing comfort and style, bed sheets can also protect a mattress from dirt and sweat, helping to extend its life. There are different types of bed sheets, including flat sheets, fitted sheets, and sheet sets, and some bed sheets may have special features such as wrinkle-resistance, breathability, and hypoallergenic properties.
