Two elements of the work remain constant: a copy of a dictionary definition of the word "chair" and a diagram with instructions for installation. Both bear Kosuth's signature. Under the instructions, the installer is to choose a chair, place it before a wall, and take a photograph of the chair. This photo is to be enlarged to the size of the actual chair and placed on the wall to the left of the chair. Finally, a blow-up of the copy of the dictionary definition is to be hung to the right of the chair, its upper edge aligned with that of the photograph.
