Me and my wife both suffer from a lot of pain in our backs , she has more in her knees and so, every mattress that we've tried has not lived up to their promises. But this one has blown us away, it's so soft and cool to the touch. Our bodies seem to adjust to this one the best we've ever had. We use to toss and turn and hardly get any sleep, but now we get plenty of sleep. We absolutely love this new mattress, we had our families lay down on them when visiting and they said that's the best feeling mattress they've seen and now want one lol.
