I bought this after reading reviews and feeling pretty confident about the purchase. There was no discernible odor like some had said. I bought the king size and cut it down to fit my queen size mattress. The first time I used it I noticed a huge difference in how I felt in the morning. I love the feeling of being cradled in cushiness. Now, two or three weeks later, I'm so used to it I don't think about it as much, but I know I'd hate to sleep without it!
