When we use the term bed linen we are generally referring to the sheets used to cover the mattress so that the sleeper is comfortable and the mattress is protected. If blankets or covers are being used a second sheet needs to be used for comfort between the sleeper and the roughness of the blankets. If a continental quilt is being used the top sheet is usually omitted.
