A well-contoured seat, coupled with an appropriate foam density cradles the sitting bones, making sure not to exert upward pressure and hence distort the tailbone curve.  It also provides enhanced support to the thighs.

A waterfall-edged seat increases the area of contact with the thighs, relieving the pressure in the area behind the knees, ensuring proper blood circulation. A slight backward slope of the seat ensures that the weight of the body remains at the back and does not slip forward.

An appropriately designed armrest height ensures that the elbows and the arms rest fully while you are working.   This will prevent shoulder pain, which comes when you have to hold up your hands without elbow support while working.

A pneumatic height adjustment cushions the impact of sitting down and prevents jerks to the spine.

A good, healthy posture can be achieved by attaining a naturally comfortable position in every task you undertake while seated, without distorting the natural `S’ curve of your spine. Hence, even if you have an ergonomic chair, you need to take care of your posture to ensure full support to your back and neck.

• Ensure that your neck is slightly forward and upper back is straight.  This reduces the cervical problems.
• Shoulders must be relaxed and your arms must hang naturally.  This reduces pressure on your back.
• Your back must have full contact with the back rest.  This supports the 'S' curve of the spine, evenly distributing the load on it.
• The angle behind the knees and the angle of your back to the seat must be greater than 90 degrees. Your body is at its comfortable best when closer to the horizontal position.  This reduces the pressure on the spine, abdomen and legs.
• Elbows and hands must rest comfortably on the arms of the chair or work surface, preventing shoulder pain.
• Thighs must be parallel to the floor and the feet must be flat, lightly resting on the floor.  This reduces pressure on the knees and feet

Therefore it is imperative that an ergonomically correct chair must be complemented by the right posture.  This will help you to maintain a healthy life without backaches.
