    An Ergonomic Critique and Redesign of a Local Cane Chair in Nigeria with User Body Mass Index. ABUA
    (ABUAD Journal of Engineering Research and Development (AJERD), 2018) Ogunwolu, L.; Popoola, O.P.; Sosimi, A. A.; Raheem, W. A.
    Furniture is designed to satisfy anthropometrical demands of proposed users and to meet intended usage. The comfort and functional utilities of the furniture depend on its physical design in relation to the physical structure and biomechanics of the human body. In this work, the design of a locally manufactured cane chair in Nigeria was critiqued with the goal of providing more ergonomic designs to satisfy both anthropometrical needs and the design goals. A novel combination of qualitative and quantitative design criteria was used in an experimental setting involving 1,000 user assessors of varying body weights and heights to criticize the design and construction of the local cane chair. Analyses of results of measurements and interviews show discrepancies in standard design parameters and the design features of the cane chair with different Body Mass Indices (BMI). Using a multi-evaluation functional design approach and two novel design criteria, alternative designs were proposed based on analyzed results for different anthropometrical measures. The results were analyzed in relation to human body mass indices, which are health indicators for various health issues including those occasioned by seating. The work demonstrated a balanced approach using both qualitative and quantitative parameters to assess and influence the redesign of a chair in an experimental setting.
