Students spend significant time sitting; thus, the suitability of school furniture for meeting students’ needs is a requirement of safety and comfort. To mitigate ergonomic risks, appropriate anthropometric measurements and furniture dimensions are needed. As such, this study proposed a design for a library desk for use by high school students. Data collected included empirical data, questionnaires, and interviews from 150 respondents consisting of 75 students and 75 librarians in Central Java. Design analysis was conducted using the axiomatic design method, which revealed three consumer requirements for furniture design: safety, adjustability, and comfort. Based on these results, a furniture design concept was created, for which a comfort level test showed improvements in comparison to the previous desk. This study can be used as a reference by school management when choosing school facilities in accordance to the student body dimension.
