<![CDATA[Background: Poor sleep quality is one of the common problems in the elderly. Non-pharmacological interventions such as chair-based exercise (CBE) are considered effective in improving sleep quality. The study aimed to determine how CBE affects the sleep quality of older people at community-based health service posts in Central Java, Indonesia. Methods: A pre-experimental one-group pretest-post test design was conducted at community-based health service posts in Central Java, Indonesia, with 30 elderly respondents selected through a purposive sampling technique. The intervention was performed for 4 weeks, twice a week. 30 minutes/session. Sleep quality was measured with the Pittsburgh Sleep Quality Index (PSQI). Data analysis using the Wilcoxon test. Results: The mean PSQI score before the intervention was 10.23 (SD = 1.80), with a maximum score of 15, and a minimum score of 7. After the intervention, the mean score decreased to 5.43 (SD =1.85), with a maximum score of 10 and a minimum score of 3. There was a significant decrease in PSQI scores after the intervention (Z= -4.583, p <0.001). Conclusion: CBE can be an alternative non-pharmacological therapy that is effective, safe, and easy to implement in the elderly community, especially in the posyandu environment, which is the center of public health activities, especially to improve sleep quality. Its inclusion in posyandu lansia programs provides a useful way to enhance sleep quality and support health promotion and prevention initiatives, without the need for medication.]]>
