A work chair is provided herein a worker wears a pelvis belt in a transverse direction from both sides of a cushion chair so as to surround the pelvis, while simultaneously wearing a safety belt between both legs and along the front of the pelvis belt in a longitudinal direction by pulling the lower side of the cushion chair, thus allowing the centering position of the cushion chair to be firmly held against the buttocks around the anus, even when the worker repeatedly sits down and stands up and waddles, and maximizing convenience of use. Moreover, by correctly positioning the cushion chair, the worker can be prevented from filling on his or her buttocks while working, thus ensuring safety during use. Furthermore, the work chair ensures that the cushion chair is centered around the anus when the safety belt is worn, whereas an attachment/detachment ring is returned upward and fitted into a collecting ring when the safety belt is not worn. Accordingly, the length of the safety belt itself is simply reduced to be small, thus preventing safety accidents. Also, the safety belt is prevented from haphazardly hanging out when storing the work chair, thus ensuring tidiness when the work chair is stored.
