A what-not is a piece of furniture derived from the French étagère which was exceedingly popular in England in the first three-quarters of the 19th century.
It usually consists of slender uprights or pillars, supporting a series of shelves for holding china, ornaments, trifles, or "what nots", hence the allusive name.
In its English form, it is a convenient piece of drawing room furniture, and was rarely valued for its aesthetic.
