Bed linen is the generally accepted term to describe anything that goes onto a bed, i.e. over the frame and the mattress – sheets, mattress covers, pillows, duvet covers, comforters, blankets, bolster covers, mattress toppers and light bedcovers. In Europe at least, bed sheets were originally made of linen. They still are, though most are made of cotton, silk or occasionally cotton and polyester mix and more recently from other vegetal fibres such as ramie and bamboo. It’s important to have good quality fabric close to the skin for the approximately one third of our lives we spend sleeping.
