Sleep quality is closely related to health risks, and its improvement has been particularly sought after in recent years. In addition, the ease of tossing and turning is known to be an important factor in improving sleep quality. However, previous studies have focused on mattresses, which are costly. In this study, we focus on pillows and propose a method to dynamically change their shape during sleep. To verify the effectiveness of this method, we developed a pillow device that implements this method and conducted experiments. Participants in the experiment continuously tossed and turned on the pillow device, which was classified according to their body movements, and their tossing and turning performance was evaluated using electromyography and a questionnaire. According to the results, the participants confirmed an improvement in tossing and turning in each evaluation, with a particularly high improvement in the lower limb-precedence type (p = 0.05). This result suggests that the proposed method can realize continuous improvement of tossability.
