Abstract: A chair foot attachment for improving focus is a flexible hollow member having a height with side walls defining bottom edges of the hollow member and having an upper wall with a cavity extending downwardly into the hollow member from the upper wall. The cavity extends only partially into the hollow member and defines a cavity height that is less than the height of the hollow member. The cavity has an upwardly facing bottom surface for abutting a bottom of a chair foot when the chair foot is installed in the cavity. When a chair foot is positioned in the cavity, it permits an associated chair to wobble.
