This is my second pad that I have bought. Although this is a different model than the first, but still as happy. These pads usually last about 3 to 4 years and that is with me rotating and/or flipping it every six months. I will rotate it clockwise and then when i make a full rotation I will flip it over and do the same thing. This model was a little softer than the first, which is my ONLY thumbs down on this product. The pad still formed so wonderfully around your body. It was great, but still a little softer to start off with than I would have liked. I can't sleep on my stomach on this on because I feel I am bending too much, and that causes pain. Usually once they start to break down this is my problem, but to start out with makes me not happy. The support isn't super on my stomach, but I did NOT have any more pain when I slept on my back and on my sides. So that in itself is a wonderful thing. I slept the whole night and did not flip flop. I will keep buying these products because I am continually pleased. I love these pads! I can learn not to sleep on my stomach to not have pain anywhere else.
