This paper is concerned with the optimal design of recliner chair frame. It is necessary for recliner chair frame that is endurable for the repeated load of human sitting. And this paper studies the selected recliner chair frame that is produced in the regional company. The company has not designed and made this chair by the mechanical engineering review. So the current frame structure and parts in this chair frame are studied and researched to develop the new frame structure with mechanical engineering design concepts. This research reported the investigation of new design of recliner chair frame by stress analysis and the verification of mechanical safety. This result will be adopted to design specification of new recliner chair frame
