Finding the perfect comfortable office chair Some of this information is provided by the office chairs guide Ergonomics (from Greek ergon work
and nomoi natural laws) is the study of designing objects to be better
adapted to the shape of the human body and/or to correct the user's
posture. Common examples include chairs designed to prevent the user
from sitting in positions that may have a detrimental effect on the
spine, and the ergonomic desk which offers an adjustable keyboard tray,
a main desktop of variable height and other elements which can be
changed by the user. Ensuring that the person's feet can rest firmly against the ground while the thighs remain level on the seat cushion. The chair should be rounded in front to avoid reducing circulation below the knee. The seat cushion, or seat pan, should feel comfortable, and the person's weight should feel evenly distributed throughout the seat. In addition, the back rest should feel comfortable; a contoured backrest will often provide greater lumbar support. Check that a number of different seated positions can be accommodated comfortably. If the person using the office
chair often leans back, make sure that doing so does not result in any
neck tension.
