More movement at the office with active office chairs

"Sitting is as bad as smoking!”. With this report scientists around the world caused quite a sensation. To make sure that sitting is not as harmful as inhaling 4000 toxic ingredients while smoking a cigarette, you should get as much movement as possible - at best directly at the office. Active office chairs offer the ideal support for this.

Sitting over extended periods makes you ill

The everyday life of the people in the western world has caused increasing numbers of individuals to spend too much time sitting. Much too long, as was impressively shown by an Australian study (Sitting Time and All-Cause Mortality Risk in 222 497 Australian Adults): According to this people whose profession involves sitting spend nearly 22 hours per day on chairs, sofas, seats or in bed. The movement deficiency due to this weakens the muscles. Sooner or later they are then no longer able to hold us upright.

This has dramatic consequences: Stomach muscles that are too weak lead to a hunchback that not only causes one-sided strain of the intervertebral discs, but also compression of the internal organs. In addition, studies provide evidence that sitting for too long also partially significantly increases the risk for diabetes, high blood pressure, atherosclerosis and thromboses, as well as for some types of cancer. Even the brain is negatively affected and starts to deteriorate earlier.

Active office chairs create movement impulses

Therefore it is recommended to incorporate as much movement as possible into the everyday working life. A good rule of thumb is: 25 percent standing, 25 percent movement and 50 percent sitting. Fortunately the industry has reacted and offers products that are able to balance the dangerous lack of movement. So sitting with the so-called active office chairs can as a side-effect incorporate much more movement.

Extended sitting concepts bring movement to the office

Active office chairs bring more movement to the workplace. This is made possible through active sitting concepts, which all allow a cushioned multi-dimensional movement of the sitting surface. Active office chairs promote the movement and ensure a greater number of position changes than standard office chairs with synchronous mechanical action. Therefore they are amongst others especially recommendable for people, who through their activities are nearly exclusively tied to a chair and therefore depend on additional movement impulses.
With the sitting concepts tested at present there are currently four different approaches.
           1. The 3D-ergonomic principle from aeris

With the 3-D-ergonomic principle the seat mounted on the spring shock absorber (individually adjustable) follows every natural and intuitive three-dimensional position change of the body in a way that is flowing and dosed. Thereby not only forward, backward and sideward movements are made possible, but also vertical oscillations as well as combinations of all movement directions.

          2. 3D-balance principle from Dauphin

The 3D-balance principle not only allows body movements forwards and backwards, but also to both sides. This supports the natural movement impulses of the sitting person. An automatic seat inclination forward opens the pelvic angle and thereby ensures an anatomic sitting posture. Apart from this it animates the user to continually change position. This stimulates the back muscles, promotes the circulation and thereby increases the concentration ability of the seated person.

          3. Similar-Swing-Seat principle from Sedus

The Similar-Swing-Seat principle promotes the intuitive movement behaviour through a seat mechanism that gives the seat a controlled, sideward flexibility. In comparison to standard office chairs this significantly promotes pelvis movements. The new seat kinematic thereby gives the body all freedom of movement and at the same time makes use of the natural body feeling of stabilising itself. The body recognises the movement impulses and picks them up as a matter of course. As the armrests do not move with the rest of the chair the sitting person retains his feeling of safety.

          4. The Bioswing technology

The 3D seat mechanism of the Bioswing chairs registers the smallest displacements of the centre of gravity of the body and automatically returns them to the body as movement impulses. These movement impulses not only have an activating and performance increasing effect on the muscles themselves, but also on the mental performance ability. In addition, through the movement impulses the deep positioned muscle layers that are important for the back health are trained and counteract monotonous sitting positions, muscle tension and pain. In addition to this, through this technology the torso muscles are stimulated, which support an upright position of the back. The general well-being is increased and in consequence the concentration ability remains maintained for longer.

5. 3D-Trimension-technology from Wilkhahn

The back benefits enormously when sitting is not a rigid, motionless affair, but the office chair provides the most varied and numerous movement impulses possible. Active office chairs with 3D-Trimension-technology stimulate flowing movements in all directions. The core elements are the independently movable seat halves coupled to the backrest, which ensure that even the smallest shifts in weight are transferred to the chair and transformed into changes in posture. In this way, new movement stimuli are created over and over, which ensure balanced, dynamic sitting behaviour.

Micro-training for the muscles

Sitting with movement has many decisive advantages. For example the intervertebral discs are no longer unevenly strained, but more evenly over their entire surface. This type of loading is not a problem for all important buffering organs. Apart from this, when sitting on active office chairs the body must continuously perform smallest movements to maintain the balance. This micro training strengthens the so-called autochthonous muscles. These are small, deep-seated muscles that are located along the spinal column. They hold us up right and stabilise the spinal column.

As required a flexible backrest not only gives additional security but also increases the selection of different sitting positions, which should be continuously changed. The backrest already offers more comfort, for example when one would simply like to lean back during a telephone call.

Active office chairs are back friendly

Like all good office chairs, active office chairs must also have easily usable adjustment facilities. Seat and back surface must be designed so that one does not start to sweat and above all does not slip. The opening angle between the thigh and the torso should be greater than 90 degrees and ensure sufficient stability.

Checklist

  • Active office chairs must support the natural change of positions as needed. So they should therefore not only allow the natural movements of the person, but also promote them.
  • As with every good office chair, with an active office chair the sitting height should also be individually adjustable for the user.The backrest must allow balanced support.
  • Should an active office chair have rollers then attention must be given that they are restrained in the loaded state. Through the additionally desired movement the chair should not roll away unintentionally.
  • Make sure that all operating levers can be easily reached.
  • If active office chairs have a vertical swinging function then this must be adjustable as needed. Just as the sitting height can be adjusted for the user.
  • The chair must support the user in active sitting, complex movements like rocking or turning must be just as possible as active sitting in front (working) position or passive back relieving sitting in slightly reclining (resting) position.
  • Even with all this movement ability the chair must stand securely in every sitting position and must not wobble or slide away.
