Previously ergonomic chair was the one that gave support to the lower back. This is actually one of the most important support, but our chairs have evolved a lot and now we can count on adjustable feet for various body parts, which brings much more comfort and significant increase in productivity and quality of life.
The adjustment of the backrest is also very important so you can relax the muscles, because the user can not stay long in the 90° position.
Sitting is an anti physiological position can cause great pressure on the spine. When sitting, the pressure is 50% higher than when we are standing. So no one can remain long sitting in the same position.
When a chair has adjustable backrest, people tend to slip to relax the muscles. On doing so, they sit on the sacrum (the end of the spine) generating a pressure in the intervertebral disc, which causes herniated disc. As it is right to sit on your sitting bones (two small bones that feel the gluteal region), when the chair has adjustable backrest, you can relax by moving only the column and remain sitting on your sitting bones.
The seat should be adjusted to a height where you can keep your feet flat on the floor.
Forearms need to be at 90 ° with respect to the arm and shoulders and wrists can stay in a neutral position.
The best chairs with ergonomic qualities allow alternating postural while are able to avoid the discomfort of the position for longer periods.
