A majority of business houses, lack the knowledge that sitting and working on an improperly designed chair, most definitely leads to a unhealthy workforce burdened with back pain. An improperly designed chair will not encourage an `S’ curve, which is the natural shape of the spine. In fact you will find that an improperly designed chair makes you assume a `C’ curve posture which is a distortion of the natural `S’ curve.

Frequency of complaints in work environment :
A survey conducted among male and female office staff reveal that the frequency of back complaints and the use made of the backrest show a clear need for adequate backrest design.
Improper seating can cause a host of problems to your spine. The incorrect `C’ curve that you acquire in a bad chair puts extreme pressure on the disc. This in turn causes the nutritive fluid to be expelled and makes the spine dry and stiff, leading to severe pain when flexed back into the original position. Prolonged sitting in this incorrect posture can cause the discs to swell and this presses against the nerve causing severe pain.
A badly designed chair without a proper back rest will force the spine to keep the upper body erect without support and this will lead to muscle and ligament strain. This weakens the tissue over a period of time and hence your back will not be able to perform the task it was formerly capable of doing.
A plush chair with a very soft seat forces the spine to assume a slumping position. This then exerts pressure on the discs leading to back pain.
Designer furniture manufacturers seemed to be filled with flights of fancy to produce chairs that look good but are not functional. As a result you now even buy sacks filled with polystyrene granules to sit on.
Chairs that one buys because friends recommend it may not be the right chair. What suits others may not suit you.
Hence both at work and at home, we should install chairs that suit our individual needs and gives us good postural support.
