    Abstract: A removable message board can include an attachment piece including a message displayed on a front side and a back side opposite the front side. A coiled spring can include a first end that directly contacts the back side of the attachment piece and a second end opposite the first end that is wound along a length of the coiled spring to form a concentric circular shape configured to press against a chair back. A top surface of the coiled spring can be oriented towards a bottom surface of the coiled spring. The coiled spring can be disposed behind the attachment piece such that the coiled spring can be substantially covered by the attachment piece when viewed from a position perpendicular to a length and width of the attachment piece.
