I bought my Steelcase Leap V1 from a guy who did just that - bought chairs from office sales, replaced bad cushions, cleaned and greased them up, then resold them out of his garage. Bought mine early pandemic. Still feels as good as when I bought it.
Used office chair from some company that’s just replacing all their furniture, you can score $1500 chairs for a few hundred.
