3D Intelligent Suspension Technology

Our work with Yves Béhar achieved a breakthrough in seating technology. Support is molded directly into the 3D Intelligent back material. The suspension material is stretched from the Y-Tower at the back of the chair just as cables are stretched from the towers of a suspension bridge. The tension is greater in the transition areas, from the thoracic to the lumbar areas and between the lumbar area and sacrum. "Hinge points" allow these areas to flex and support the healthy, forward rotation of the pelvis. At the same time, less tension in other parts of the back encourages a full range of seated movement.


 
 



   


 

The foundational shell of the upholstered work chair mimics the 3D Intelligent suspension. That gives the upholstered chair a healthy balance between support and freedom. An optional lumbar support for the upholstered work chair provides adjustment over a four-inch range.
