It's probably early to write a review since there probably needs to be a few months of trial use to get an accurate review. But I'll give you my perception so far. It shipped quickly. We allowed it to expand/breath/whatever for a couple of days. There was a little bit of an odor. But that was expected. Then my wife and I both laid on it for a while just to see how it felt. Amazing. Both of us agreed that it was so much more comfortable for our backs. We expected it to be hot, but it actually had a cool feel to it. This was a gift to my son at college. He loves it. I can't see how you can go wrong with this. For this price, you could buy a new one every couple of years if you wanted and you still wouldn't come close to what you would pay for the more popular brand mattresses. I research everything. I review everything. This was a good buy.
