A chair gas lift allowing easy disassembly is revealed. A gas lift is disposed between a seat cushion and a chair base of a chair. By extension or retraction of a piston rod of the gas lift, the seat cushion height is adjusted. At least one polygonal ring assembly is arranged around a circumference of the gas lift. Due to the polygonal ring assembly being mounted in an opening of a wrench, a force is applied to the wrench to remove the gas lift from the seat cushion easily.
