The study was to evaluate the overall comfort and good and bad points in the design. The methodology for evaluating this single chair, rather than making a comparison among chairs, was developed from previous chair studies. The methodology was found to be quick and effective when applied to a modeled chair, giving information to institution head or users from institution on overall comfort and good and bad points in the design. Testing took place on twotasks: the use of measures which compare the chair against chair design principles and anthropometric data and evaluate chair experimentally at the real workplace. Thirty office workers individually used the chair for one day. The results showed that overall comfort of was quite comfortable, and cross tabulations between chair feature checklist or anthropometric data together with users’ personal details (stature, weight, age),and general comfortprovided significant relationships. The chair features which related to overall comfort included chair height, chair depth, chair width, seat slope and the backrest curvature; while anthropometric data together with personal details that related to overall comfort included age, weight, width of bitrochanterand sitting shoulder height. Finally, chair comfort is influenced by ergonomic design principles and furniture design.
