I am so disappointed at having to write this review. I received this mattress topper at the beginning of 2/10 and I LOVED it at first. It did not smell and it was comfortable (although softer than an actual Tempurpedic.) Now, a few months later, it is absolutely unusable. The foam in the middle of the topper has broken down and is visably and by touch broken down. I woke up with such a back ache this morning that I knew I had to write a review to warn others. I am disappointed because it was so nice at first - now I have to buy another mattress or mattress topper, and have to go through the hassle of trying to figure out what to buy.
