An interchangeable button system along with methods for its use and manufacture are disclosed. An interchangeable button system according to embodiments includes a base and a button. The base may comprise an attachment point for attaching the base to a piece of furniture and a fastener opposite the attachment point. The button may comprise a button base and a fastener. The base may be attached to a piece of furniture using the attachment point and a button may be removeably coupled to the base using the fasteners such that different buttons may be interchangeably coupled to the same affixed base. These different buttons may, for example, have buttons that are of different shapes or sizes, are covered with different upholstery, made from a material that may be left uncovered or that may differ from one another in some other type of aesthetic or functional manner.
