Office work puts a strain on your back. He who sits a lot sins. And whoever sits wrong on top of that gets it in the cross. Correct sitting and an ergonomic office chair can prevent back problems. This is how ergonomic sitting describes the optimal posture of the body in a chair. But why is an ergonomic chair useful for your back at all?
Ergonomic office chairs make long periods of sitting comfortable
An ergonomic office chair that is tailored to the user allows fatigue-free, comfortable work even after hours. Ergonomics is therefore becoming more and more important, especially in the office. Because back pain also hurts the employer. Musculoskeletal complaints are the most common cause when employees are absent due to illness, as the absenteeism statistics of the health insurance companies show. You move too little if you sit in a rigid posture in front of the computer for too long. The muscles that are responsible for holding work are loaded on one side. The consequences of one-sided stress range from muscle tension and back pain to a herniated disc. In order to take the strain off your back, you should change your sitting position more often when working. And make sure that the chair and body size match.
How do you sit ergonomically?
If you want to protect your back, you should set up your workplace ergonomically, i.e. with as little strain as possible. An ergonomic office chair is adjustable in height and seat depth. The thighs and lower legs should form a right angle when sitting. The person sitting should be able to make full use of the seat surface and still have two to three finger-widths of space between the hollow of the knee and the front edge of the seat. So that the muscles in the shoulders and arms do not become tense, the upper and lower arms also form a right angle if the armrests are correctly adjusted. The seat and backrest should move with every movement of the body. The backrest ideally extends to the shoulder blades and supports the spine. The back should be in direct contact with the backrest. This should be adjusted so that the upper rear pelvic area is supported so that the back remains straight when leaning against it.
Some ergonomic office chairs also have a lumbar support to support the normal posture of the spine. Doctors refer to the forward-facing, natural S-curve of the spine as lordosis. The lumbar spine usually has lordosis. So it is bent towards the stomach and is held by the muscles. If these relax, the spine turns into a backward curve. A bad posture can fix itself. An ergonomic office chair with a lumbar support counteracts this.
