Many of the elements of The Chairs are ironic, which means that the intended meaning is different from the actual meaning. This sense of irony contributes to the absurd atmosphere. The Old Man has a very important message to give to the world, yet all of his invited guests are invisible.
The Old Man hires an Orator to broadcast his message. Yet the Orator cannot effectively communicate because he is deaf and mute. These and other uses of irony in The Chairs underscore the play's thematic concerns.
