I’ve got one of those generic office chairs that has an adjustable pneumatic height tube. I’ve had it for years.
Recently, the height tube seems to have sprung a leak somewhere (or something) because when I sit on it, it slowly descends to the depths of its minimum height. (To add insult to injury, I’ve been losing weight that past few months. So it’s not my fatness.)
Anyway, is there any hope of fixing this? I don’t even know where to look on the chair itself for things to seal up, it’s just a tube inside of another tube.
