Old office chair gas cylinder stuck? 

Although only wedged in place the old gas lift can become quite stuck over time. Although the mechanism on the underside of the seat should lift off the gas lift relatively easily, they can get stuck with time.

If it is ‘stuck’ you will need to persevere as it will eventually ‘wedge’ free. Usually,  it is freeing the 5 star base that causes most problems. Try using some lubricant such as WD40 or washing up liquid and then, from beneath, tap the underside of the old gas lift with a soft mallet (so as not to damage the 5 star base) until ‘pops out’.
