I went for a used chair from https://www.crandalloffice.com/

They completely replace the foam seat, so its really only the frame that was used. Significantly cheaper than buying new and safer than buying used from eBay/garage sale/etc.

The seller on amazon swapped out my chair, so it’s not available anymore, but is perfect to me because:

• Mesh bottom (and back) doesn’t wear out easily, get hot, or get smelly (yup, I said it)
• Adjustable bottom goes back and forth so you can align it to your knees
• Arm rests go up down and back and forth, which allow for better adjustments based on desk height
• Back tapers in so you dont look like a child sitting in a giant seat when on video calls
• Adjustable back height and lumbar support allow you to get the contour just right

Personally, I’d find an affordable chair with as many adjustments as possible, like the one described. Fit is soooo important.

Just keep in mind that the scratchier the office chair, the more productive the worker… Up to a point, then you’ll go mad.

I got a used Herman Miller Aereon that had the arms all fucked so I replaced them and it will last another 10+ years.
