AI Technical Summary

Problems solved by technology

Some existing office chairs have armrests, and some do not have armrests, but no matter which one is mentioned above, its structure is usually fixed and single, and the armrests cannot be adjusted to meet the needs of different working environments

At the same time, the fixed structure also makes it inconvenient to disassemble and assemble these chairs, and takes up a lot of space during transportation, which is not conducive to packaging and transportation

In addition, daily sitting for a long time makes people gain weight inadvertently, and the existing office chairs lack a weight detection structure, which cannot arouse people's health awareness

[0003] Therefore, the existing office chairs have the problems of single structure, inability to meet diverse needs, inconvenient assembly and disassembly, and lack of weight detection devices.
