Abstract: A backrest pad for attachment to a chair having a backrest formed from transverse slats. The pad comprises a sheet of padding and a hardboard panel encapsulated in a sturdy and flexible cover forming an outer envelope for the pad. The cover also extends from the top and bottom edges of the padding and panel to form a pair of flaps on the envelope for embracing a portion of the slats to fasten the pad thereon. The envelope is formed by two sheets of material which are so shaped as to require a minimum number of seams while yielding a sturdy and highly functional pad.
