A hot-cold cushion includes a heat/cool device, a connecting tube and a cushion with circulating pipes. The heat/cool device composed of a thermo semiconductor chip, a thermoconductor, a fan, a heat dissipation member, a box with liquid, and a hydraulic pump is connected with circulating pipes inside the cushion by the connecting tube so as to form a circulation loop. By exchange of the positive/negative electrodes of direct current, the thermo semiconductor chip produces heat or cold that is circulated and dissipated by the heat/cool device so as to regulate the temperature of the cushion into a suitable range for human bodies. Therefore, the hot-cold cushion achieves better effect.
