Under the background of global tourism, the work aims to discuss the design strategies and methods of urban furniture adapted to the spatial system of mountain trails to enhance the spatial adaptability and interesting experience of urban furniture. From the differences in the crowd, function demands and cultural identify, the influence factors and key points of urban furniture design were analyzed, and based on the space and product integration theory, a design strategy model of symbiosis and co-construction with urban furniture as the "spatial state" of mountain trails was put forward and applied to specific design practice. The symbiosis and co-construction design idea of urban furniture and mountain trails can effectively promote the systematic and local construction of urban furniture, and realize the reconstruction of spatial vitality with urban furniture under the integrated thinking of "product" and "space", and improve the perception and experience of the audience with urban furniture design. While satisfying the sense of identity of local residents and foreign tourists, it also provides a reference for the design strategy and method of upgrading related types of urban furniture.
