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.
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.
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.
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.
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.
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.
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.
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.
