[0002] An office chair refers to various chairs that are used for the convenience of work in daily work and social activities. For this reason, there are two definitions: narrow and broad. The narrow definition refers to the chair with a backrest that people sit on when doing desk work in a sitting position. The broad definition refers to all chairs used in offices, including meeting chairs, staff chairs, conference chairs, visitor chairs, training chairs, etc. However, no matter what kind of chair it is, various lumbar diseases will inevitably occur after sitting for a long time, so office chairs that can protect the lumbar spine have appeared.

[0003] In the existing technology, the seat cushions and backrests of office chairs currently on the market cannot be folded, resulting in the office chairs taking up a large amount of space, causing inconvenience in transportation and storage. In addition, existing office chairs are equipped with massage functions to improve the user experience, but these functions are difficult to disassemble, resulting in the office chairs being unable to be folded and stored. Therefore, to solve the above problems, the present application provides an office chair that is easy to fold and store. Utility Model Content
