The work aims to investigate the main factors that influence users' intention to use stress-relief products in office settings and provide suggestions for the design of such products. Qualitative and quantitative methods are combined to determine the key factors that users focus on when evaluating stress-relief products for office settings through qualitative research, including user interviews, surveys, and literature review. Based on the factor analysis method, the data analysis in quantitative research provides relatively objective and fair theoretical basis and data support for the results of qualitative research, and the mapping relationship between related factors and users' intention is explored. Based on behavioral research, the design is studied and the specific design strategies are proposed from three perspectives of quality of use, quality of seduction, and quality of function. Resonance, usability, and calm are the important factors affecting users' intention to use stress-relief products in office settings. Resonance, usability, and calm have a descending order of influence on users' intention to use stress-relief products in office settings according to the variance explained. They are key factors in improving users' intention to use such products and also the main focus in designing stress-relief products for office settings.
