Chaise, n. – chair; also, a horse-drawn carriage for one or two people; but, can also be used as a metonymy to represent a role or authority held in a hierarchy, interchangeably with simply using “chair,” “throne,” etc … The use of this term seems to imply an honorary or ornamental position as in a position of leadership in a social group, not necessarily utilitarian as in the chair of a legislative committee.
