If anyone knows if these toppers are toxic, please let me and others know. I tried to research this on earlier posts but did not see anything regarding this. I bought a thin memory foam topper to put on top of my mattress pad. Like everyone else, I thought that I would sleep better with this foam under the sheets. There is a really strange odor though from the foam and this is after I have aired it out for a few days. I am really afraid to use it because it might create more problems than it is going to solve. Please write if anyone knows that these foam pads are toxic to our health.
