The incentive seating module comprises: a structural frame provided with a
gaiter, a frame, disposed above said structural frame and provided with
an arch, whereby the structural frame exhibits planar symmetry, means for
connecting the frame to the structural frame comprising a joint enabling
the frame to swivel in relation to the structural frame about an axis
which is perpendicular to the symmetrical plane, and a seating element
joining the frame to the gaiter, made of an elastic membrane which is
used to define a rest position for the frame in relation to the
structural frame and to return it towards said position when a user
causes it to tilt in one direction or the other.
