I have to laugh at myself. I am one of those people who looks and looks, usually not finding anything. The stools and chairs in my house have always been a bit tall for my sewing machine. I make do but I have to lean over and after awhile, my back starts to hurt. Not good posture. I have sat on every bench or chair that I though might work for about the last fifteen years. I do the same with rocking chairs.
I found a bench in Bellingham. It is 18 inches high and wide enough for Koda Bear to join me. Or there is room enough for him to sit on my lap. I am so enjoying the sewing, even though I am very tired. I came back to work with people out. The sewing, the spinning, the gardening are helping to relax me after a hellish day. And now my back does not hurt. That is just work a smile.
