Secondary school students spend at least five hours in school and their activities circulates in
classrooms, laboratories, workshops, and sports lessons as part of their learning processes.
School furniture gives a high impact on their posture habit. They can develop musculoskeletal disorder and back pain if mismatch occurs [4, 26]. Bad posture was among the risk factors associated with discomfort while doing these activities. Pain is usually related with static posture, sitting arrangement and loads carried. Students tend to show a variety of postures while seated and performing tasks regardless of the furniture [15]. Different postures may contribute to different sites of discomfort. On the other hand, they are prone to adopt flexed postures when working at the desk. To conclude, it is important to investigate all relevant risk factors in order to identify the postural stress among students [22].
