The present invention relates to a smart cushion and, more specifically, to a smart cushion providing vibration in real time to allow a user to recognize an incorrect posture when the user sits on the cushion in the incorrect posture, so as to assist posture correction and inform the user of a schedule. To this end, the smart cushion comprises: a piezoelectric sensor installed at upper, lower, left, and right parts inside the cushion to generate an electric signal by a pressure generated when the user sits thereon; a vibration motor installed corresponding to each piezoelectric sensor installed at the upper, lower, left, and right parts to generate vibration; a communication module to communicate with a portable terminal of the user; and a control unit detecting whether the weight of a user is concentrated on each of the upper, lower, left, and right parts based on the electric signal generated from the piezoelectric sensor installed at the upper, lower, left, and right parts to operate ...
