Introduction: Using human data and observing local manufacturers of domestic products for imported furniture seems necessary to design and manufacture sofas with ergonomic indices. This paper uses data from the study of human population. The design process from the perspective of ergonomic furniture and product design consists of ergonomic principles such as shape and posture in the correct state and consideration of parts of body that need cushion for protection.

Methods: In this research, anthropometric data of 150 males and 110 females between the ages of 25 to 35 were measured. The calculations were based on a sample size sofa to gather user evaluation.

Results: After analyzing the measured results of a similar internal investigation using SPSS software and combining them with ergonomic principles, the optimal size sofa measurements with all angles for Iranians adults was calculated and the results were compared with the dimensions of the furniture.

Conclusions: Seat height and backrest height and width, respectively 37, 57 and 62 cm, the angle of 105 degrees between the seat and the back, and the slope of 5 degrees for the seat surface are suggested as the standard.
