At home, my sewing machine is sunk in a cabinet and I have an awesome Koala chair that really is the most comfortable I've found. However, I'm taking classes at the Houston Quilt Festival and the machines are up on tables . . .and the chairs are hard and YES . . .my bottom hurts . . .and my lower back. In fact, it was so bad, I returned to my room for the night at 6pm, LOL
