Sitting correctly becomes easier when the office chair is adjustable. A good office chair should be individually adjustable in height so that your legs form an angle greater than 90° when seated. At the same time, your arms should also rest on the tabletop at this angle. It should also be possible to adjust the angle of the seat so that an angle of at least 90° or more can be maintained due to the different body sizes.

The chair’s padding should be soft enough to prevent back pain. This applies to both the seat and the backrest. The latter should also be adjustable in height.

A height-adjustable desk also makes sense. This allows for adjustment to an employee’s individual height as well as switching between a sitting and standing posture.

Thus, the screen and the viewing direction face each other at a 90° angle.

Several health problems can be caused by wrong sitting positions:

It is all too easy for the shoulders to slump forward while working at a desk, causing the back to arch. The head falls likewise forward, which loads the neck musculature strongly. Even the distance between the eyes and the center of the screen, which should be about 50 centimeters, is usually not observed.

Instead, a forward-leaning posture is often adopted in order to be closer to the screen. A hunchback is thus inevitable.

This is also the case when the keyboard and mouse are positioned too far from the edge of the table or when the forearms cannot rest parallel on the tabletop. In addition, a lack of grounding of the feet contributes to poor posture while sitting.

If your feet do not find stable support, you will easily slip away from the backrest of your office chair. This results in unnecessary strain on your legs and back. Staying in one position for too long also puts strain on the intervertebral discs, which in turn leads to back pain.

Consequences of a bad sitting posture

The consequences of incorrect posture are reflected in the above percentages regarding the causes of work absences. In addition to sore back and neck muscles, an awkward posture constricts the digestive organs and lungs. Digestion problems and a flat respiration adjust themselves. The latter entails fatigue and increases susceptibility to infectious diseases.

Other consequences include joint problems in the feet, knees and hips, as the connective and supporting tissue of the joints tends to become inflamed more frequently.

Even lasting disturbances of the movement sequences can occur. But not only physical symptoms can be observed as consequences of a bad posture. Also the psyche is connected with the attitude.

An upright posture, with a straight spine, promotes self-confidence. Drooping shoulders and a hunched back not only make people around you perceive you as less self-confident, but you also feel less self-confident yourself. This can increase through despondency to the development of depression.
