Interesting facts about healthy and active sitting

Ergonomics is the science of human work.
The term ergonomics is made up of the Greek words
“ergon” (work) and “nomos” (law, rule) .

This means adapting working conditions to people and not the other way around.


The aim is to create a good working atmosphere and to design the conditions in such a way that the least possible

health burden arises. Especially in the office area, with predominantly seated activities in front of the screen,
the ergonomic design of the workplace is absolutely necessary. 
This includes adapting the chairs, tables, keyboards and screens to people. Poor posture can cause significant health damage. Ergonomic sitting means having an optimally adapted office chair and a table that can be adjusted to the right height. But it also includes getting up at least once an hour, even if you don't have to.  

Ergonomics at the workplace


Three primary seating positions

active sitting

Sitting must not be a static state.

The upper body should move as freely as possible.

A good chair follows these movements to optimally support the body weight at all times.

There are three primary seating positions:


1. Sitting upright, with body parts at right angles to each other, is considered very healthy.

In this position, the chair can absorb the weight of the body and the relaxed 90° angle between the thighs and torso prevents the organs from being compressed.


2. Sitting facing forward should be supported by a seat tilt adjustment, otherwise the angle between the torso and thighs is less than 90° and the abdominal cavity is thus compressed.


3. In the reclined position

it is easier to work with and, above all, easy to read. It is important to adopt this posture in order to exhaust all movement possibilities and to relax the back muscles from time to time.


In general, it is important to move around in the chair and not to remain in one position. A good work chair should promote this active sitting through its ergonomic shape and versatile adjustment options.

The seat should support the thighs almost to their full length, while the hollows of the knees need enough space to the front edge of the seat (knee roll) to prevent bruises and consequent blood stasis.

The seat height must be adjustable so that both feet can rest flat on the floor.

The correct shape of the seat prevents the pelvis from tilting in the rear area.


The healthy support of the lordosis area

(Lumbar vertebrae three to five or 17 to 22 cm above seat height) is achieved by a height-adjustable backrest. This must have a correspondingly shaped curvature  exhibit. In addition, it should be oscillating or softly padded and ideally have a depth-adjustable lumbar support.

When working at a desk in particular, a backrest that reaches up to or beyond the shoulder blades improves performance.


Supporting arms and legs

Exceptions are the rule


Different seating situations require

different chairs. If the adjustment range of the normal seat height is not sufficient, you can get almost any of our models with extra high gas springs.

To the ergonomic posture and  continue to ensure safe use,  according to the Work Chair Ordinance DIN 68877 extra high chairs with climbing aids or height-adjustable Foot ring fitted, and the casters will be replaced against gliders or rigid loads stop rollers.


Our footrests offer another way of relieving your legs. They are particularly recommended when your feet do not reach the floor at a regular working or sitting height.

The use of armrests is not appropriate in every situation, but it brings decisive advantages in the distribution of body weight: the trunk muscles are relieved by up to ten kilograms with the right armrests. This makes it easier for you to work in a concentrated and relaxed manner for longer.


Adaptable furniture

Pain-free throughout the day

Improper posture at work can cause serious damage to health. If you can set your devices at the right angle to each other, you save yourself back, joint and and headaches and experience concentrated and at the same time relaxed work.
