I must admit that the topper is working quite well. However it is not exactly what I expected. It is a rolled up queen-size sheet of foam. I thought it would have some sort of cloth cover. It doesn't. I put it on top of my mattress and placed my fitted sheet on top of that. It worked OK. It was a bit softer than I was expecting being directly on the foam. Not bad, but it being summer I felt quite warm as I felt I was "sunken in" a bit into the topper. Was it psychological? Maybe. I then put a thin cotton topper I had onto the foam topper. This made the bed a bit firmer (I didn't sink into the foam) and I felt cooler. I definitely slept better. Was it worth it? Yes. My bed is now super comfortable. It is especially worth it if you feel cold or want a softer bed. It is definitely comfortable even just by itself. I, however, felt odd being directly on top of the foam. I needed the cotton topper as an extra layer. If the foam had been in a (washable!) cloth covering, it would have been perfect.
