Abstract

This study evaluates the effectiveness of an ergonomically redesigned office chair, tailored to meet the anthropometric needs of employees. It addresses common issues associated with prolonged sitting, such as musculoskeletal discomfort and fatigue, which are prevalent in sedentary work environments. Utilizing anthropometric data from prior studies, the redesign incorporates modifications in key chair dimensions—such as seat height, seat depth, and backrest height—to enhance user comfort and reduce physical strain. The ROSA (Rapid Office Strain Assessment) tool was employed to assess posture and ergonomic risk for both the old and redesigned chairs. Findings indicate a significant improvement in ergonomic support and comfort with the new design, supported by a statistically significant reduction in ROSA scores, as confirmed through a paired sample t-test. Although the redesign effectively enhances comfort, further improvements are recommended, including adjustable lumbar support and backrest flexibility. This study underscores the importance of ergonomic adaptations in office furniture to support diverse body types and reduce occupational health risks.

Abstract

Many students at Politeknik Industri Furnitur dan Pengolahan Kayu have reported musculoskeletal discomfort after prolonged sitting in classroom chairs, including lower back pain, neck stiffness, and shoulder tension. These complaints suggest that the existing chairs may not accommodate users’ anthropometric characteristics. This study aimed to evaluate the ergonomic compatibility of current student chairs and to redesign their dimensions based on anthropometric data to meet both national and international ergonomic standards. The research was conducted through three main stages: (1) identifying discomfort areas using the Nordic Body Map (NBM) questionnaire, (2) collecting key body measurements from male and female students, and (3) performing a mismatch analysis between anthropometric dimensions and chair parameters. The analysis revealed a high level of mismatch—particularly in seat height, depth, and backrest dimensions—which correlated with the prevalence of MSD complaints. A redesigned chair model was then proposed based on student anthropometry and evaluated against available standards. The redesigned dimensions significantly reduced mismatch rates for both male and female users, indicating improved ergonomic compatibility. Alignment with international standards further supports the potential of this design to enhance comfort and reduce musculoskeletal risks. However, despite its functional improvements, the new chair proportions may appear less visually balanced, necessitating further refinement in aesthetic and structural aspects before implementation.
