I've been a long time Tempurpedic client and huge fan. My first tempur pedic mattress was purchased in 2009, and eleven years later, I was still happy with it. It was time for a king size mattress, and the quality is not the same. After a year, we were sinking in the mattress, to the point you couldn't roll over. We returned the mattress and upgraded to the luxbreeze firm...a year later we are finding the same problem. It has softened so much in the middle that it is difficult to roll over. We have rotated the mattress, but still having the same problem. Hugely disappointed in the decrease in quality. After many years of recommending tempur pedic, will no longer do so. I can't emphasize enough my disappointment. After such a large investment, we are stuck with a mattress that does not aid in a good nights sleep, and causes back and shoulder pain.
