摘要： The present invention relates to a prefabricated chair and, more particularly, to a prefabricated chair separated into two frames so that the volume thereof can be remarkably reduced, thereby facilitating storage and transportation and enabling easy assembly without a separate tool. The present invention relates to the prefabricated chair in which a first frame and a second frame are coupled, wherein the first frame includes: a pair of first and second leg bars of the front and rear; first and second upper horizontal support bars for connecting the upper portions of the first and second leg parts; an upper bracket for coupling the first and second upper horizontal support bars; first and second lower horizontal support bars for connecting the lower portion of the second leg part; and a lower bracket for coupling the first and second lower horizontal support bars, the second frame includes: a pair of third and fourth leg parts of the front and rear; a third upper horizontal support bar for connecting the upper portions of the third and fourth leg parts; and a third lower horizontal support bar for connecting the lower portions of the third and fourth leg parts, and the third upper horizontal support bar is fitted and coupled to the upper bracket and the third lower horizontal support bar is fitted and coupled to the lower bracket such that the first frame and the second frame are assembled in + shape.
