Does anyone have experience of using natural materials like sheepswool, straw or wood fibre? Data is hard to find for these things. I have a client who has a preference for an all-natural solution.

Hi Bayou, I have looked for this data myself but can also not find. I have used cotton and denim which have no published absorption data that I could find. I took the thickness and density and compared it with our foam technology to get some numbers to work with.
