Since I aged to about 50 years old it became harder to sleep for the pain in the shoulders, ribs and hips, so I toss and turn because I am a side-sleeper. But this is a great topper. This topper provided 4 pounds of 3 inch foam for the base and I added a 3 pound 1-1/2 inch topper for the top layer and this layout is truly cloud nine. Ya know, they use the same concept of layering for the memory foam mattresses. But about the smells, I am using a vinyl mattress cover and the smell on that took longer to subside than the poly smell on the foam. And with all of the other bedding pads, covers and sheets you really need to experiment to get the right combination for a total sleep solution. I am currently very happy with mine right now, best sleep I have had in years.
