I have a severe sensitivity to odors. They trigger my asthma. In all the write ups about buckwheat pillows, I never saw reference to the fact that buckwheat hulls have quite a strong smell to them. Therefore, I was never able to use the pillow. When I inquired about returning it, there was such a large fee involved that it really was not worthwhile packing it up and shipping it back. The advice I got was to empty out the hulls and let them air out. I had already done this....it has been several months since I started airing them out and the smell is still too strong for me to tolerate. I'll give it some more time, but had I known about the odor, I certainly would never have ordered the pillow.
