I purchased this pillow for the feel and cooking aspect. After a couple of days using it, I was progressively getting more and more dizzy during sleep and when I tried to get out of bed. I would rollover in the middle of the night and instantly wake up so dizzy. I thought something was wrong with me, but it only happened in bed. It went on for about two weeks, and I finally decided it might be the pillow because it was the only new thing in my life.  I stopped using the pillow and that night no dizziness. I haven’t been dizzy once since then.  Be aware of this with this product.
