Going to touch on several points so this may seem scatter brained. Several friends that have purchased the very expenseive Tempurpedic mattress have stated that they never have slept so well. Friends that have purchased the knock off versions from OverStock and other websites have stated the same. I would say that is a slight oversell. Don't get me wrong, this mattress is wonderful but not the best sleep I've ever had. I've had a few drunker stoopers that helped me sleep better. :) The smell is just as bad as the other reviewers have stated. It smells like fresh paint. After running the fan on high for 24 hours, all is well. We threw a mattress pad on it and is in use now. After a month, I sleep very well and I don't have pain in my shoulders anymore as I am a side sleeper and a convertional mattress was pressing on the the wrong spots. It was a Sealy Posturpedic (piece of junk). The cooling gel is great and I have not sweat while in bed. I've had friends that have stated that it can be difficult to be "intimate" with your wife as you tend to sink into these types of mattress. I can report that is not the case with me. :) This mattress was actually just the right amount of firmness and ended up being even more comfortable for my wife. Overall, very good product for the cost. You will sleep better but this isn't a life changer. Hope this helps.
