Laundry business is popular service business in Indonesia that mostly involve muscle activity for lifting and ironing activity. It causes the worker get muscular fatigue and injury especially for ironing activity that is included in the static and monotonous activity. moreover, existed ironing board design in the market is not easy to be adjusted to standing or sitting position of workers. Hence, this paper aimed to design the innovative and adjustable ironing board to minimize the musculoskeletal complaint. The preliminary study is conducted by NBM questionnaires found that fatigue experienced mostly in the back, right upper arm, and calves. The product designed by Kansei engineering to satisfy consumer's feeling and assessed by USE questionnaire to fulfil consumer's usability. Orthogonal array and conjoint analysis were conducted to incorporate all attribute potentials in developing a new single concept design. Statistical analysis was also done to test the hypothesis. 80 respondents have participated in this study. The result of this study is an innovative design of ironing board which is valid to meet consumers' needs such as comfort, secure, attractive, sturdy, durable and multifunction and practical at 5% of the significant level.
