This study clarified the relationship between the weight and management methods of movable chairs. In installing movable chairs in public spaces, there is a risk of the chairs being blown away by the wind and a risk of malicious acts such as chairs being thrown, and to counter these risks, methods such as making the chairs heavier or removing them during storms or at night were observed. Moreover, in public spaces where lightweight chairs were installed, managers moved the chairs around depending on the time of day or during events to improve the comfort of the public space.
