Are office chair cylinders universal?

The model, size, and brand of each swivel chair  are different, and the model of the pneumatic rod is also different. Therefore, the gas bars of office chairs, gaming chairs, and swivel chairs are not universal.
So do not disassemble the lift chair at will, especially the gas spring parts, if you need to repair, please ask a professional to do it. Some people think it is dangerous to have gas inside the chair lift, so they disassemble it themselves to release the gas. Users are warned that consumers should not follow the tutorials that appear on the Internet to disassemble the chair lift by themselves to deflate, so as to avoid danger.
