It is so comfortable for side sleepers, it's incredible. Definitely too soft and thick for stomach sleepers (it will give you back pain). Pretty nice for back sleepers, also. We bought this in the Spring and it's still holding up well. I can image with heavy use, however, that it may have to be replaced every couple of years for that "Oh my God this is Heaven" feeling, but this is what I would expect from a topper. We got this at a great price, there were no problems unfurling it, there were no bad spots, and smell was not an issue. We let it completely air out and decompress over a period of about two days in our finished basement. This was my first order from Great Offer Stock, and the product and Overstock's service has been top notch. I recommend this product and company without reservation.
