The work aims to explore design ways of healthy furniture in the "third space" for office under the set of the transformation of office space, office people's pursuit of higher level of health experience, as well as the development trend of "healthy" office furniture. The characteristics of the "third space" for office as well as the health requirements of professionals were analyzed. Then based on the experience design and the case study of healthy furniture, regarding physical and spiritual needs as the lead, furniture experience design model was constructed from five experience modules of sensory, emotion, behavior, cognition and social contact. At the same time, the research pointed out that the current products were inadequate in realizing the psychological healing, cognitive enhancement and personal fulfillment needs of people in the workplace. And then, in order to increase the effectiveness of furniture in emotional care, cognitive promotion and self-satisfaction through the combination of different experience modules, the work put forward three optimization paths including immersing in the emotions related to "home", creating diversified ways of interaction, and combining interests to guide community activities in the furniture design of the "third space" for office. It can meet the diversified health needs of office staff, give furniture more profound connotation of health and improve the furniture experience value of the "third space" for office.
