Bedding, also known as bedclothes or mattress linen, is the materials laid above the mattress of a mattress for hygiene, heat, safety of the mattress, and decorative effect. Bedding is the detachable and washable portion of a human sleeping environment. Multiple units of bedding for every mattress will typically be washed in rotation and/or changed seasonally to enhance sleep comfort at varying room temperatures. In American English, the word bedding generally does not include the mattress, mattress body, or mattress base (comparable to field-spring), whereas in British English it does. In Australian and New Zealand English, bedding is often called manchester.
A set of bedding normally consists of a flat or fitted mattress sheet that covers the mattress; a flat high sheet; either a blanket, quilt, or duvet, sometimes with a duvet cowl which can replace or be used in addition to the top sheet; and plenty of pillows with pillowcases, also referred to as pillow shams. may be added to make sure the necessary insulation in cold sleeping areas. A standard practice for kids and a few adults is to embellish a mattress with plush stuffed animals, dolls, and different gentle toys. These should not included beneath the designation of bedding, although they could provide extra heat to the sleeper.
