How do quilts, quilts, and sheets differ?
Quilt covers generally refer to quilts, and the cotton and gauze that cover them are collectively called quilts.
The quilt is a “big pocket”. The quilt is inserted into the quilt to prevent soiling of the quilt, and the quilt can be changed and washed frequently.
When laying directly on the bed, the person sleeping on it is called a sheet, which is usually called a sheet.
