The invention is based on a mechanism () for a chair having a synchro mechanism by means of which a seat surface structure and a backrest structure are moved in a synchronized ratio relative to one another, wherein the mechanism () serves to adjust a restoring force of the synchro mechanism to a different body weight of a seat user by changing a working angle of a force accumulator, and the mechanism () includes a seat support () for the seat surface structure, a bearing yoke (), the force accumulator unit () a backrest support () for supporting the backrest structure, and a translational bearing (), wherein the mechanism () has a triangular steering block () and the force accumulator unit () is connected to the triangular steering block (), and on a weight adjustment method for an improved dynamic sitting experience on the part of the seat user by means of a mechanism () for a chair with a synchro mechanism, in which the position of a first pivot point () of the force accumulator unit () is shifted by means of the adjuster () when the backrest support () is in a position (A), and a swivelling motion of the backrest support () into a second position (B) is not performed until the first step is completed.
