You can tell the chair has one when you sit down, if
you're heavy enough at least. The chair seat goes down
after it's sat on. (Maybe comes part way up, esp. if
you stand up a little. Definitely comes up the rest of
the way when you get off the chair.)

You appear to be talking about the gas (hydraulic?) height adjustment COLUMN
(not "strut"). If it goes down when you sit on it, it is broken.
