Aiming at the problem that the community seat has single function and cannot meet the social and emotional needs of users, an emotional community bench-mobile bench is designed. The deformable structure of the mobile bench can not only add a variety of functions of the design interesting and real, but also enable users to sit normally and sit on the ground: it can be used by a single person, and it can also choose to sit with peers and sit face to face, which can meet the use needs of different user groups in different scenes. At the same time, children can use the mobile structure to create game channels, add fun, but also reduce the burden of parental care.
