Take the design of the rest seat as an example. In the form of the seat, the psychological needs of different groups should be fully considered and diversified designs should be carried out: the linear seat is suitable for single use or two people; The "L" shaped seat is ideal for conversing with friends who are not familiar with it because it is easy for users to turn around and face the seat in a friendly but not awkward way. Due to its centrifugal effect, the circular seat is suitable for the use of individuals who are not good at communication. The backside of the seat can avoid the embarrassment caused by the line of sight communication between strangers. The concave seat is very similar to the curved seat. The concave seat has centripetal effect, which is good for small groups to talk, and the convex seat has centrifugal effect, which is suitable for individual users. Because of the highest degree of privacy and centristing effect, the sitting type is more suitable for large-scale group organization communication activities with eight to ten people
