This paper is based on the position of the elderly group in Anhui Province, and combines the performance of the ease of use of furniture products in the interior design of senior living buildings to propose a set of furniture ease of use evaluation system consisting of 4 dimensions of practicality, economy, aesthetics, and sociability, as well as 12 secondary indexes and 36 tertiary indexes. Subsequently, based on the performance data of furniture products in 10 senior living places in Anhui Province, the entropy weight-TOPSIS method was used to calculate the entropy weights and weights of each index, and the furniture was ranked according to its ease of use performance data. Five commonly used furniture products in the 10 senior living places were selected as experimental objects, and the correlation analysis algorithm was used to calculate the confidence level of the rules between the furniture products and the 36 third-level indicators. Among them, the indicators of “ergonomic furniture scale” and “purchase price” have higher confidence level with multiple furniture products, which indicates that the most concerned factors in the purchase decision of elderly furniture products are the comfort of the elderly and the price of the products.
