For those in the UK, I recommend Studio Modern (https://studiomodern.co.uk/) for refurbished chairs. I have only bought one chair from them (Mirra 2), but was originally recommended it by someone who has bought dozens for offices.

I've had 2 mirra chairs at home for years, I think they were ~£120 off ebay each and are ridiculous value for money.
