Haider BioSwing 660 iQ Trendline Chair was designed and built in Germany and is the only ergonomic office chair that does not use a fixed connection from the seat to the ground.

The Haider BioSwing 660 Chair uses a free-hanging mechanism as well as 3D technology. The 3D seating system provides controlled and free movement between the backrest and the seat. This allows the body to be ergonomically aligned when sitting, without any lateral tilt for a more comfortable posture.

Active movement and regular posture changes are good for your spinal column. With the standard **individually** **adjustable seat tilt** **adjustment** and **pelvic stabiliser** with a wonderfully soft response, you can easily align your pelvis correctly and at the same time position your spine in the **natural** **S shape**. This activates additional potential for the body and mind.  
  
The BioSwing 660 IQ Trendline also features:

-   Ergonomic office swivel chair with orthopaedic effect
-   Integrated, adaptive 3D seat mechanism
-   Synchronous mechanism with automatic weight adjustment (along with fine adjustment)
-   3D armrests for multifunctional adjustment to suit various working positions
