The start button is great to give your foot a rest (left or right). I've had a Janome 9000 for quite a few years and love it. A while back, someone wrote a post about the "lumbar" supports that you can purchase at Dollar Tree. I bought one and it is great. It is a mesh-type "thing" that has straps and slips over the back of your chair. I have a secretarial chair (no arms) and it works great with that. I think it will fit most chairs. It has a nice curve and feels good behind your back. The catch is that they must have become so popular that the two Dollar Trees that are closest to me have sold out. I should have bought more when I got my first one. I keep checking back and hope they get more. Cannot go wrong to spend $1.
