Promising review: "Nothing helps you sleep better than this mattress. Nothing. Night one it was comfortable, firm, cool to the touch, and felt like a hug. Night two I realized that the edge was not as firm as a standard mattress, but then again it was not hard on the edge. I realized that I have been sleeping on the edge of my mattress and it was not doing me any favors. The Casper changed my body alignment in the bed and I am glad it did. After a week we both agreed it was a good mattress. After a month we decided to keep it and discarded our original mattress. It has been over a year now and I would not trade the Casper for anything. I played college football, weigh over 300 pounds, have bad knees, hips, shoulders, and back, but this mattress allows me to get out of bed without any pain.
Now lets discuss the cooling effect. I used to sweat every night in my old bed. The Casper breathes, period. I do not sweat at night any more. It is cool in the summer and adjust perfectly to your temp in winter. And then there is the motion of the mattress. Ask my wife and she would tell you that I never get up in the middle of the night anymore. It is not true, but she just does not feel it. I don't feel her get up in the mornings either. If you took the time to read this review, then do yourself a favor and try this mattress." —David Lopshire
