Bedding +

Bedding, also known as bedclothes, refers to the materials laid above the mattress of a bed for hygiene, warmth, to protect the mattress, and for decorative effect. Bedding is the removable and washable portion of a human sleeping environment. Multiple sets of bedding for each bed will often be washed in rotation and/or changed seasonally to improve sleep comfort at varying room temperatures. In American English bedding generally does not include the mattress, box spring or bed frame, while in British English it does.
