The increasing elderly population has led to a growing demand for furniture designed to enhance their quality of life. This research aims to design and develop a multifunctional table and chair set for the elderly by applying the Quality Function Deployment (QFD) technique. The study began with an investigation of the daily activities of the elderly, followed by an analysis of customer preferences regarding multifunctional furniture. A questionnaire was developed to assess the importance of various customer needs, which were then used as input data for QFD analysis. The analysis was conducted using two matrices: (1) a product planning matrix, which translates customer requirements into technical specifications, and (2) a design transformation matrix, which identifies the correlation between design elements and pinpoints weaknesses in sub-assemblies requiring further refinement. The research results show that the newly developed product has improved design, quality, materials, functionality, and cost-effectiveness. A prototype was subsequently evaluated by three groups: (1) potential buyers of multifunctional furniture for the elderly, (2) manufacturers, and (3) rubberwood furniture users. The findings indicate that customers rated modernity of form and structure as the most satisfying factor, with an average satisfaction score of 4.59. Additionally, functionality and versatility ranked second, receiving an average satisfaction score of 4.53. The research demonstrates that the designed products can effectively meet the needs of their users.
