April 1930s has the bed cushions (feet) (free shipping) for $5.95. You'll have to dig the old ones out, but it's doable. You may have to lubricate those screws, but keep working on them, they'll come out. I just took off a set today, and one was a real toughy. Try a search for the light switch. Sometimes on Ebay there is a machine being parted out.
Good luck...
