This research aims to study and apply the Quality Function Deployment technique in conjunction with anthropometric measurements to design a workbench suitable for individuals with lower-limb disabilities. The House of Quality matrix was employed as the primary tool to link user requirements with technical specifications. In the first phase, user needs were collected through questionnaires and translated into technical requirements based on product standards. A relationship matrix was then constructed to evaluate the importance of each requirement. In the second phase, anthropometric data were collected from 15 individuals with disabilities at the Redemptorist Foundation for People with Disabilities. Nine key measurements were taken, including seat height, knee height clearance, leg width clearance, forward reach range, side reach range, elbow height, wheelchair width, eye level height and wheelchair turning radius. These data were used to define appropriate dimensions for the workbench design. The results from both phases were synthesized to develop a prototype that reflects user needs and accommodates physical limitations. The evaluation of the importance rating showed an average increase of 5.93% after prototype development, with the highest improvement observed in the safety and stability dimension (11.03%), indicating the effectiveness of the design in meeting the needs of wheelchair users.
