Background: The chairs used by mothers performing Kangaroo mother care (KMC) in hospitals in Indonesia are not ergonomically designed, so they can cause an awkward posture and musculoskeletal disorders. Objective: The purpose of this study was to create an ergonomic sofa design that would reduce musculoskeletal disorders among mothers who perform KMC in Indonesian hospitals. Methods: The research method was based on the Nigel Cross concept and involved anthropometric measurement conducted with 69 postpartum mothers from four hospitals in Indonesia as a basis for designing an ergonomic sofa. The sofa design was assessed using virtual human modeling with the Siemens Jack software for posture and lower back analysis. Result: The Rapid Upper Limb Assessment (RULA) value of 2 and low back analysis (LBA) of 363 N obtained with virtual human modeling showed that a mother who performed KMC with the ergonomic sofa was in a safe position with a low risk of experiencing lower back injuries. The resulting ergonomic sofa design had adjusted to the anthropometry of mothers in Indonesia. The mother's posture with a simulation using the ergonomic sofa design is easily maintained and acceptable and can be categorized as safe to the user. Conclusion: The ergonomic sofa design for KMC potentially improves posture and reduces the risk of musculoskeletal disorders. Further tests are needed, including prototype production and pilot testing, to determine its effectiveness.
