This study aims to explore the application of semiotics and semantics in bionic furniture design, incorporating digital quantitative research methods to uncover consumers’ needs and preferences. By utilising user preference surveys, market analysis data, and user feedback, the study reveals key insights into bionic furniture design. It was found that semiotics enhances the cultural depth and aesthetic value of designs by drawing on natural symbols, while semantics aids designers in better understanding users’ cognitive and emotional responses, thus optimising the functionality and experience of bionic furniture. The results demonstrate that comfort, design style, and functional requirements in bionic furniture design are closely linked to consumers’ purchase intentions. Through digital quantitative analysis, this study offers an innovative theoretical framework and practical guidance for future bionic furniture design, helping designers create products that align more closely with market demands.
