I have back problems and I use an adjustable height desk and stand when I sew. It has done wonderful things for my back, my PT thinks it's because instead of sitting passively I'm constantly adjusting my position and forcing my core muscles to do more work. I looked at the tilting Martelli but it was way out of my price range so I went to the office desk store and got lucky in the scratch and dent section. My machine doesn't go down into the table though so that might be the deal breaker. If you have an ortho or a PT they might have a good suggestion
