Detailed explanation-1: -No matter how comfortable one is in an office chair, prolonged static posture is not good for the back and is a common contributor to back problems and muscle strain. To avoid keeping the back in one position for a long period, remember to stand, stretch and walk for at least a minute or two every half hour.

Detailed explanation-2: -Sitting for prolonged periods of time can be a major cause of back pain, cause increased stress of the back, neck, arms and legs and can add a tremendous amount of pressure to the back muscles and spinal discs.

Detailed explanation-3: -A bad posture at the computer usually begins when you sit with hunched shoulders. To simplify, hunched shoulders are when you roll your shoulders forward. This position increases the curvature in the upper spine and pulls your head and neck in an unhealthy tilt. In addition, it also decreases your lung capacity.

Detailed explanation-4: -In 2006, Canadian and Scottish researchers found that sitting straight is bad for backs. Their findings came from MRI scans which demonstrated how an upright posture when seated can place unnecessary strain on the spine. They concluded that the optimum position when seated at a desk is leaning back at a 135° angle.
