I bought a great office chair with lumbar support . When you reach out your hands to sew and piece, Your arms extended to the table should be right at the same height as your hands, and you should not have to lean down or forward to sew. Before I have a good light source, I found I was dropping my head to see the needle area closer. With 5 back surgeries under my belt, I am very careful. At the very least, I never chain piece...trying to get up and down as much as possible.
