Ergonomics review: Balans seating

 

Sitting & seating  |  Anthro  |  Ergonomics  |  Children  |  Disabled  |  Health  |  Design  |  Humor

This white paper reviews the scientific literature relevant to the design and use of the Balans® seat concept, and compares it with conventional and alternative seating.

The Balans® seating concept was developed in the 1970's by Hans Christian Mengshoel and designer Peter Opsvik in response to a growing recognition of the limitations of conventional seating from Mandal (1976).

This Balans design is characterized by an open thigh-torso angle and lower leg support that flex (bend) the knees and support balanced movement. Although often referred to as a "kneeling chair" or a "knee-supported chair", the actual locus of lower leg support on the Balans seat is below the knees and at the shin to reduce potential loading at the knees.
