The Apex Chair was the seat of the Kai in the Vedek Assembly.

In 2376, Yevir Linjarin and Solis Tendren sought the Chair, although Solis admitted he was only seeking to oppose Yevir. When Opaka Sulan returned to Bajor, she urged Solis to seek the Apex Chair to help the Bajoran people. (DS9 novel: Bajor: Fragments and Omens)
