I found the adjustable office chairs were still too low.
Then found an drafting chair ... same idea, though it's lowest setting is the highest of the office chair.
Low is perfect for working at the sewing machine and the higher heights let me sit comfortably to work at higher places ... cutting table, ironing board etc.
I chose one with arms, as I knew I'd want to use it at times, while doing hand sewing, or as I sat back and reverse stitched, etc. Best to get adjustable arms, height and tilt, as sure enough they'll collide with the table as you sit up to it.
