A google search led me to a site which has a futon dust mite protector for 6 to 8 inch thick futons. Would that be to big for the 5 inch futon? Here is the site: http://www.nofeathersplease.com/product/BARMATZIP8
What do you think of this? Is that a reasonable price? I don't really care of organic or non-organic for the protector cover, but I definitely want a 100% cotton and no synthetics or vinyl.
Everywhere else were protectors for standard mattresses and not the thinner futons.
