From the perspective of furniture material CMF, this research analyzes the embodiment and application of the concept of availability in the design of furniture material CMF. By explaining the origin of the concept of availability and its development and application in the field of product design, it is extended to the design of furniture material CMF. Furthermore, availability serves as a medium that connects the environment with the user's experience and behavior, and the research explores in detail the impact of the availability of colors, materials and surface treatments on users, constructs a furniture material CMF design process based on the concept of availability, and taking the existing excellent furniture products as an example, the feasibility of applying the concept of availability to the design of furniture material CMF is explored. Moreover, the research summarizes three stages based on the concept of availability, and proposes a method of furniture material CMF design for each stage, so that furniture can better grasp the direction of furniture design from the perspective of color, material and surface treatment, and improve the use experience value of furniture products. By introducing the concept of affordance into the research of furniture material CMF design, it can guide the process of furniture material CMF design and provide corresponding theoretical applications for the actual furniture design process.
