Some time ago, I began to practice the method of disconnecting the gas lift from the piastra - using the so-called "gas", i.e. - pipe wrench. Our company has many new chairs, including inexpensive ones. But nevertheless, due to defective gas cartridges, it was necessary to remove the piastra (i.e. the entire upper part of the seat) from the gas lift to replace the latter. You need to grasp the gas lift cylinder with a key as high as possible, literally under the piastra bushing, and try to twist it. Well, and after that, the gas cartridge body is knocked out of the crosspiece with rollers in the same way as before.
