EXPLORATION Knee Sit Posture Chair.
Knee sit posture "chairs" have been around for some time. Although rather popular, there is a rather large body of information regarding the ergonomic validity of such chairs, such as knee joint pressure, back rotation during work tasks, stability and adjustment. This design addresses these issues with a knee pad that has a flexing support to accommodate movement and perch height adjustability. It also has linear wheels which support in and out movement without the issues of rotation.
