A chair is removably mounted to the floor of a theater or other assembly hall so that it may be quickly removed when needed to provide space for a patron using a wheelchair and quickly reinstalled afterwards. Holes are formed in the floor of the theater, in a generally square pattern, and plugs are positioned in each hole. A baseplate upon which the chair is permanently mounted has plug-engaging members depending from its underside. The forward plug-engaging members slidingly engage the forward plugs, and the rearward plug-engaging members are biased to latchingly engage the rearward plugs. A special tool is inserted through access holes in the base plate to overcome the bias and disengage the rearward plug-engaging members. The tool includes a pair of wheels joined by an axle so that when the rearward end of the chair is tilted forwardly after disengagement of the rearward plug-engaging members and the rearward plugs, the tool is inverted and inserted through a different pair of holes in the base plate to form a dolly that enables the chair to be carted away. No tools are needed to reinstall the chair.
