Ergonomics is a key factor to consider when buying office furniture. Fortunately, these days, most furniture pieces are designed with the user's comfort and convenience in mind. Still, it is beneficial for us, as consumers, to be aware of the do's and don'ts, for example, the right way we place the computer monitor or the right way we sit working at the computer. All these good habits will ensure we don't sustain injury in the long run.
Let's just look at the Correct Sitting position. Many of us think that sitting upright is ideal actually we should sit back in the chair between 100° & 110°, (Not 90° or straight upright), with thighs parallel to the floor. Place your feet firmly and evenly on the floor and slightly in front of you (the knee joint is at an open angle).
Following these steps will reduce disc pressure and muscle tension significantly as this position places less stress on the joints of the lower extremities and distributes body weight properly to avoid pressure points.
