I purchased a Tempur Pedic Cloud mattress 16 months ago. The first 5 months or so I found it quite comfortable.
Since then, it has gotten progressively less comfortable. So much so that it has caused a buldging disc in my back. I have also found that I can only sleep on my side. Any other position causes extreme pain in my back, even if I am just in the position for a few minutes.
Although I have the recommended amount of supports on my bed frame, I am going to try additional supports as well as a back board to see if anything helps before I start trying to make a warranty claim.
STAY AWAY FROM THIS EXPENSIVE MISTATKE!!
