I love this mattress. It's heavy and well made. It fits and looks nice on the bed. The sheets fit good. I don't find it too be hot. There was no odor at all. It expanded to full size within 2 or 3 hours. It is very firm which is what I needed. No more tossing and turning. Thanks to the reviews I found this great deal. You can't go wrong with this one unless you like a soft mattress.
