Our bed had a featherbed underneath the mattress pad and even with this softness, my right hip would become sore overnight, and my low back would suffer. I saw the memory foam 'cool' topper on your website and decided to go for it. It arrived quickly and opened up to its full size within a couple of hours. The odors are still there after a month of airings indoors and outdoors, but much, much less. I am more tolerant to the odor than my wife is; however, she put on a set of plush sheets and is mighty pleased. The good news is that I have no more hip aches or backache after a full night's sleep. We both are sleeping better, and I would not hesitate to recommend this product to a friend. My only "four-star" is appearance: the sides of the mattress topper are not exactly straight, but who notices when it's made up? It's a great product.I appreciate the coolness because my feet get hot in an ordinary bed and it's no longer a problem.
