I delayed reviewing the product to give me time to figure out what works about the pillow. I bought a pair and it is a waste of money. After several weeks I finally removed them from the bed for good. I can't return them so they are stored until I finally give up and donate them to charity. They are hard as a rock and don't give me appropriate support...they don't give in any way. I tried sleeping on my side and back and all I noticed was they consistently gave me a stiff neck. I do not recommend them. They are not at all what I expected.
