What makes a good Office Computer Chair? Office Chair Functions and Mechanisms

Hand on heart, do you know what office chair functions your chair has ?
Do you know what makes a good office chair ?

 No ?

No problem - we will show you which office chair functions are important to ensure healthy screen work even on long working days.


Office chairs are often advertised using innumerable technical terms that sound nice, but the normal user has no idea what that actually means.
Therefore, in this article, we also explain common mechanisms and terms of the office chair.

Useful office chair functions

The right office chair with appropriate functions is important for a healthy sitting posture! 

This overview shows which elements are absolutely necessary on an office chair for daily use in the office :

  • ✓ Backrest: Every office chair needs a backrest. It supports the back and relieves it.
  • ✓ Seat height-adjustability: Everyone has an individual height. Therefore, the seat height must be individually adjustable for everyone.
  • ✓ Armrests: Even if you don't think so, armrests are important. They help to relieve the shoulder and neck area.
  • ✓ Rocking The tilting  the rocking mechanism relieves the strain on your intervertebral discs enormously.

Details on the basic functions

Office Chair Backrest :

It should be possible to adjust the height of the backrest! 
An important aspect that defines a good office chair is its backrest:
Ideally, this should not be rigidly locked to the chair and offer the possibility of individual adjustments in height and inclination.

This is necessary to adapt the chair to your own body. Tall people also benefit from neck support.
This can also relieve the neck and shoulder muscles. Also, pay attention to the various height settings.
Office chairs whose backrests are covered with mesh ensure better air circulation on the back.

Chair Seat height adjustment:

Every office chair should be adjustable in height!

Nowadays, almost every office chair can be adjusted in height - usually via a gas pressure spring.
The optimal sitting position is achieved when the upper and lower legs form an angle of at least 90 ° to one another - a larger angle is also kind to the back.
If the office chair changes hands frequently, particular care must be taken to readjust the optimal height.

Office Chair Armrests:

An office chair without armrests is an absolute "no-go" in the office. Office chairs where the armrests are adjustable in height and width are best, as this ensures that the forearms can rest comfortably and loosely on the armrests.
This relaxes the shoulders and neck areas in particular. Soft armrests are particularly good because they do not cause pressure points on the forearms.

Office Chair Rocking mechanism :

The locking mechanism provides valuable relief for the back muscles when leaning back. This model also has adjustable armrests.

Many modern office chairs have a rocker mechanism. If you press your back against the backrest, it will tilt backward.
This relieves the intervertebral discs and ensures that you are not in a monotonous posture.

Often you can set and adjust the resistance for tilting the backrest individually. An important function, because not everyone has different physical characteristics.
As a rule, the strength of the resistance is set using a dial under the seat.

Office chairs that meet these criteria are Our tip: Make sure that all control elements for adjustment are easily accessible.


Optional, higher-quality office chair functions


More  is always possible - This overview shows the mechanics with which even more ergonomics can be added to the office.

  • ✓ Lumbar support: This small arch is used in high-quality chairs so that the lumbar spine is optimally supported
  • ✓ Seat tilt adjustment: People who work a lot in front of a computer benefit from the tilt angle adjustment of the seat
  • ✓ : tipping 2.0 - The synchronous mechanism corrects poor posture and relieves the back

Ergonomic office chairs are not necessarily more expensive than many basic models: take a .

Details of the high-quality mechanics

Office Chair Lumbar support :

Lumbar support ensures stability in the lumbar region while sitting!

High-quality models are offered by lumbar support, which is nothing more than an arch in the lumbar vertebral area that provides additional support for the lumbar spine.
Lumbar supports can also be found in car seats, for example, and offer the back more comfort and support.
The height of the bulge can usually be adjusted individually.

Office Chair Seat tilt adjustment:

Seat depth and seat tilt adjustment can be found in particularly high-quality models With a seat tilt adjustment, the tilt angle of the seat can be adjusted. The slightly sloping seat counteracts a backward displacement of the pelvis.

The seat tilt adjustment thus compensates for incorrect posture when working forward and is ideal for people who work a lot on the computer.

Chair Synchromechanics:

Better than the classic rocker mechanism: the synchronous mechanism. Here the seat and backrest move in different proportions!

In the case of an office chair with a synchronous mechanism, leaning against the backrest, together with the seat surface, follows the body's movement.

The synchronous mechanism corrects bad posture and relieves the back. Synchronous mechanisms are often found in very high-quality office chairs that enable so-called ."

In concrete terms, this means that the office chair continues to provide optimal support for the back even when the actual sitting posture and position change.


The maximum / recommended sitting time for an office chair.

Some manufacturers indicate the maximum recommended sitting time in the product data!  is not the same swivel chair.

It is tempting to buy a cheap office chair from the hardware store and use it for work in the office, with many factors influencing whether an office chair can also be used as such in the office.

The most important is the recommended sitting time : A swivel chair with a sitting time of 8 hours per day or more is mandatory for use in the office.

Cheap models usually only offer a sitting time of 2 or 4 hours per day. These office chairs are, therefore, only suitable for domestic use and should preferably not be used in the office.

What exactly does the Chair's specification of the maximum or recommended sitting time say?

If the maximum or recommended sitting time for an office chair is stated to be 4 hours per day, this specifically means that from 4 hours of sitting time per day, pain and damage to the health of the back can occur.

The indication of the recommended sitting time can be found in the product sheets and operating instructions for the respective office chair.

Instructions: optimally adjust the office chair

An optimally adjusted office chair is a prerequisite for healthy office work.  experts will show you what to look out for in these brief instructions :

  • You will achieve the correct seat height when the front edge of the seat and the hollow of the knee is at the same height when you are in a straight position.
  • Upper and lower legs have an angle of at least 90 degrees. If you do not achieve this, we recommend using a  (  )
  • If your back is on the backrest, you still have 1 to 2 finger-widths between the edge of the seat and the hollow of your knee (important for the blood circulation in the legs!).
  • Adjust your backrest so that the back is particularly well supported above the pelvis.
  • Use the rocker or synchronous mechanism of your office chair as often as you can!
