This is the 5th mattress topper that I have purchased from Overstock.com. I was a little disappointed that it was not all memory foam but am finally getting used to it. It did not have the strong odor of the other toppers we have had. We received it very quickly using the standard shipping and were able to use it that night! I love the fact that the separate eggcrate top can be turned over if we should like to do so. Would definitely reccomend it!
