Abstract: A stool apparatus for permitting a user to sit while using a sink. The stool apparatus includes a frame assembly being designed for being pivotally coupled to a cabinet positioned below the sink. The frame assembly is pivotal between a stored position and a deployed position. The stored position is defined by the frame assembly being positioned in the cabinet. The deployed position is defined by the frame assembly extending from the cabinet. A seat member is coupled to the frame assembly. The seat member is designed for being positioned a distance from the sink when the frame assembly is in the deployed position. The seat member is designed for supporting the user in a seated position when the user is using the sink.
