I have an Ikea high back "executive" office chair - in quite good nick,
other than the gas lift has just died. Operate the lever with no weight on
the chair and it drops to the bottom.

I hate throwing perfectly good stuff away. Any tips on how I might source a
new gas strut - and, before I bother taking it to bits (as it still sort of
functions as a chair), is it generally feasible to repair these things?

Ta,

Tim
