The present invention relates to a swivel chair provided in a variety of workplaces including an office and providing comfort to a person who sits thereon. The swivel chair comprises: a rotational support unit (130) into which a height adjusting unit (120) for the swivel chair is inserted and which carries out a support function in the rotating process of a seat cushion unit (110); an upper leg unit (10) in which first, second, and third upper plates (12, 14, 16) with two branch legs integrated, where the height adjusting unit (120) is inserted and rotate, are radially laminated apart from each other at a predetermined angle; and a lower leg unit (20) touching a lower portion of the upper leg unit (10) and having first, second, and third lower plates (22, 24, 26) with two branch legs integrated, which are combined with the first, second, and third upper plates (12, 14, 16). As the rotational support unit for the swivel chair is configured to be divided into the upper leg unit and the lower leg unit so as to be assembled, the present invention minimizes a welding portion necessarily required in the process of manufacturing the swivel chair, thereby simplifying the manufacturing process. |
