I bought this as my new Topper mattress is too hard (bad buy: 5 minutes in the store to try not replaced now times a night to sleep on it). The topper feels very good and did not have the feared bad smell, as described here in some reviews (smells just beginning to "new"). The first night, however, I could not sleep on it. It was me then too soft and in my lateral position I went with her hips so much that I got pain (incidentally I weigh 58 kg). In the following night, I had the good idea to set my slatted lumbar fixed. That helped: I'm better now kept in the hips and have no more pain. Thus I have the intention to redeem these toppers to a firmer, discarded. What now, however, still bothers me is that it is very warm and I sweat it. I am considering to buy me for the summer a topper from another air-permeable material, and this one to keep for the winter. 4 stars, visit, despite everything, because he really feels good, you easily it is and you can rotate very well from one side to the other (it does not get stuck in a Kuhle, contrary to my fears). That he is a little too soft and too warm is my personal preferences and not on the quality of the Toppers.
