1. A dynamic proactive system for supporting sitting while detecting and automatically changing sitting postures of a user, said system comprising:
a frame;
a plurality of supports, each of the plurality of supports is configured to support and move a different body part of the user;
a plurality of joints each configured to move independently of or together with any other of the plurality of joints, wherein each of the plurality of supports is connected to the frame via a corresponding joint or multiple joints of the plurality of joints, wherein at least one of the plurality of joints is a two dimensional or a three dimensional joint such to enable a change in angle between the frame and a support corresponding to the two or three dimensional joint;
at least one motor connected to said plurality of supports for moving said plurality of supports;
system sensors for measuring forces and pressures applied on the user by the plurality of supports;
physiological sensors for measuring physiological parameters of the user; and
a controller for controlling operation of said at least one motor, thereby to control movement of each of said plurality of supports with respect to said frame or with respect to another support of said plurality of supports, to enable any change in sitting postures of the user and to mimic natural human movement;
wherein said controller receives the measurements measured by the system sensors and the physiological sensors;
further wherein said controller automatically changes position of the plurality of supports, based on the received measurements.
