Throughout the history of furniture design, it’s clear that wood is the most popular material used in furniture making. As one of the common wooden furniture, the strength of wooden chairs is an integral part of the furniture design process as it relates to the user’s experience and safety. Therefore, research on the strength of wooden chairs is becoming increasingly important. The purpose of this study is to test the strength of wooden chairs of different design structures and woods to improve the aesthetics and safety of wooden chairs. The research method is to conduct a quantitative study using the finite element method. with the following specific research process: firstly, a questionnaire survey was conducted to understand people’s subjective impressions and needs for the strength of wood and connection structures. Secondly, the general physical properties of the wood were summarized, and the selected seat samples were modeled with different connection methods, and the model was pre-treated, then external loads were added and finite element analysis was carried out. Finally, the results of the experimental data were analyzed to obtain the optimal strength combinations of different woods and connection methods in the design of wooden seats. The results of the study showed that among all the experimental samples, the white oak seat with a screw-connected structure had an equivalent force of 20.327 MPa and a safety factor of 0.29517, which was the strongest among the 15 experimental samples. The strength of the screw joint structure of all five kinds of wood is greater than that of the Roundwood mortise-and-tenon common structure, while the strength of the Roundwood mortise-and-tenon joint structure is greater than that of the straight mortise-and-tenon joint system. In this study, the strength of solid wood seats was investigated based on the finite element analysis method, which provides specific theoretical support for the design and research of solid wood seats in the future and has particular reference significance for promoting the design and development of solid wood furniture in the future.
