The chairless chair is a kind of ergonomical product which is actually a chair that is based on exoskeleton support. The primary work behavior of workers who have been listed as prolonged occupational standing reported that the worst health outcomes. A small study concluded that there stands a higher chance of significant and prolonged lower limb muscle fatigue while standing five hours or more than that a day. This might increase the risk for long-term back pain and musculoskeletal disorders. In mean time, the researchers found that people who primarily stand at work are several percentages more likely to develop heart disease than “predominantly sitting populations”. The traditional chair is inconvenient to carry to different working locations due to its large size, and its heavy weight (5 to 7 kg approximately) and rigid structure and thus, they are inappropriate for workplaces where enough space is not available. The ultimate aim of this project is to develop a lower body cost efficient external skeletal structure that supports sitting, walking and partial standing posture. Flexible wearable chair may have gross weight of 3 kg as it utilizes lightweight members. It is to be fabricated in such a way that the workers can be cozy during their tasks and can alter their sitting postures at any angles between ninety degree to hundred and sixty degree. A person can utilize this exoskeleton like an extra pair of legs to give him or herself as support to sit without a chair or to adopt a more comfortable position for different tasks. Workers can walk about as typical, but if they want to sit or lean, adjust and fix the supporting structure in the required position. Then the weight is supported on the ground by means of their adjustable structures. It aids to save space in the working place as the workers wear it on their legs. It reduces bad health impacts that occurs due to excessive standing.
