If you would like to see how this would work for you, without all the expense, you can get 2 rubber door stops - wedges - & put them under the back of your machine to tilt it towards you. I understand that it is supposed to be better for your neck & back, but when I tried it, I found I preferred my machine bed flat. But for just a couple $$, you can try the door stops & see if you like it.
