The stairs that the title of House of Stairs refers to are a significant symbol in the novel. Outside of the epilogue, the whole narrative takes place in this enclosed, bare environment, which is only defined by its unfamiliarity and lack of logic. Peter first describes it as follows: “Without railings they rose and fell at alarming angles, forking, occasionally spiraling, rising briefly together only to veer apart again, crossing above and below one another, connected at rare intervals by thin bridges spanning deep gulfs” (2). He also notes that the stairs don’t make sense structurally; they shouldn’t be able to stand, and yet, they do. This setting creates a sense of unease that enhances narrative tension and intrigue. Through the prose, William Sleator replicates the protagonists’ confusion as they repeatedly attempt to make sense of their environment.

In the epilogue, Dr. Lawrence finally explains the crucial purpose of the stairs in relation to conditioning: “It was essential for the food to be the only thing that wasn’t unpleasant. If everything else is terrifying, alien, and uncomfortable, how much more intensely gratifying, and necessary, the one pleasurable element will be” (164-65).
