I have fibromyalgia and rheumatoid arthritis. After reading all of the reviews on this product and how it helps with these particular conditions, I was convinced to buy it. The reports of comfort and better sleep seemed to override the consistent complaint about the scratchy pillow cover. When it arrived, I simply covered it with a sheet and will sew a cover at some point. However, I do think it behooves the manufacturer to supply a better pillow cover, and to possibly offer one at a discount to those who have already purchased the pillow. I'm still working on how to best use the pillow, but I will say that it does mold around your body nicely. The extra support on the back is helpful, as I've been rolling up towels and using small pillows to supplement the king size pillow I was using. The only negative for me is that it does tend to retain body heat. I have and will continue to recommend this pillow.
