Good
Not smelly, and I have bought about 3 to 4 of these, and they work on a hard mattress. Have to love this product, I have Fibro, and back problems plus arthritis and this with or without the Gel Memory will help you with pressure pain. I could not sleep without this product, I have tried 4 different types of Mattresses, Pillow tops and all and nothing helps me like this memory foam does. Now I must tell you the first week and it does take a week with ever memory foam that I have gotten it seems to be a little bit more solid for some reason, but after that first week I am ever so happy. It may just take it that long to return to it natural size because it come smashed down kind of solid in a box wrapped very tight. If you are a person that lives with chronic pain, muscle soreness,s back pain, arthritis, etc. you may be very surprised as I was to find this really works.
