A quilt is a type of bedding that is large enough to cover the human body. It is usually rectangular and is used to keep warm and comfortable during sleep. Quilts are usually made of a quilt cover or a sheet wrapped in cotton wool. Quilts made of cotton are called quilts. In addition, blankets, also known as wool blankets, have the same function as quilts when used as bedding. In addition to quilts, they can also be made of artificial fibers such as wool, silk, camel hair, soybean fiber, or acrylic fiber.
