I tried adjusting so that while at my sewing machine, my elbows would be at right angles like what is recommended. I hurt so bad after 30 minutes I went back to my old bad posture and was able to sew for an hour before I started to get a little sore. So I guess it depends. My "stock" cutting table is about 34" high. I'm shorter than average so I'm going to make my new cutting table 32" since I do have trouble cutting on the stock table sometimes.
