Work-related Musculoskeletal Disorder has been the top non-fatal occupational injury in the world. Despite being the leading non-fatal injury, preventive measures addressing this issue was not the top priority. This study aims to address issues in Occupational Safety and Health such as the recognition of proper and improper sitting postures, the effect of workplace element such as table, the recognition of discomfort in some areas of the body, the simulation of the acceptable torso angle in sitting posture and the relationship between body frames and sitting postures. During modelling, Decision Tree Classifier shows an acceptable accuracy of 90% and a kappa of 0.7. For the simulation, it has found out that every human body frames, the height of the office table found significant in assessing his/her comfort leading in Musculoskeletal Disorder. The study also found out that using a standard table approximately 75-80 cm in height affects the comfort of different body parts such as torso, arm and wrist. This study also found out that reclining the torso in an acceptable degree might reduce the discomfort experienced in most areas of the body in sitting posture.
