Abstract A combination chair is provided which includes a top chair stacked on a base chair and releasably coupled thereto by respective male and female fasteners. A first back chair and a second back chair, releasably coupled together are respectively fastened to the top chair and the base chair through sleeve joints. Therefore, the top chair, the base chair, the first back chair and the second back chair may be disconnected from one another for use separately, or connected together, to form a single chair, thereby reducing storage space requirements.
