1. The design of the public seat is not compatible with the urban style and lacks systematicity. The design of some public seats is outside the public environment of the city, and “self-expression” is separated from the specific environment. It does not blend with the urban humanities development and cannot play the role of coordinating the relationship between people, environment and society. For example, in many urban environments, designers always consider the design and layout of recreational facilities such as seats and stools after the design is completed.
 
2. The position of the public seat is unreasonable, and the design of the public seat does not take into account the user's behavior habits and psychological feelings, resulting in the design of the seat, the low wall, the step and other shaft-assisted seats. I have been idle since that day, and nobody cares about it. For example, in a bus stop, in front of a building, where people need a body, there is no seat to sit on, and a seat in a cold or exposed place. Physical facilities that do not conform to the habits of the public make the use of the public ellipses less efficient and do not really play a full role.
 
3. The public seat design can not better meet the needs of people. During the waiting process, people appear to be doing nothing: anxiety waiting, waiting for a long time for a single person, waiting for a long time to feel uncomfortable, and feeling long waiting time in an unfamiliar place. The singularity of the seat design can not fully meet people's waiting for demand.


 
4. The design of the public seat ignores the regional style. The design of outdoor public seating in some cities ignores the urban characteristics, and the shape of the seats is uniform and cannot reflect the urban style. The theme and personality of the urban outdoor landscape depend on the local traditional culture, and the urban outdoor public facilities are the specific expression of this culture. Especially the public seats in the outdoor environment can make people feel the culture at any time in the outdoor activities. Breath.
 
5. The durability of public seats is not strong. Because of the design and production of some seats with low efficiency, single function, improper use of materials, rough production, and difficult processing, the cost of maintenance is high. These factors are all problems that prevent public facilities from being durable when used. Outdoor public seats, regardless of design or in the process of material selection, construction, and production, must consider the natural conditions of sun and rain, and may be destroyed regardless of day and night.
