Chair, preferably without height-adjustment, for practicing concentration, composure and calmness has a sitting surface inclined forwards at about six degrees

摘要

A back support has two contact panels separate from each other and adjustable in height, which each slide horizontally towards a user's back. The height of the sitting surface's front edge amounts to about 54 cm. Combined with the contact panels and a minimum height, a sloped sitting surface allows the adoption of a eutonic posture to stimulate concentration.
