thought it would be better than last tempur-pedic

I have several herniated discs in my back and suffer through a good night's sleep. My old Tempur-Pedic was great except it would get hot and certain extra curricular activities were difficult due to the sinking. When it finally reached it's due age I decided to try something new. After only one year and in spite of several turns the Dormeo has developed a huge hump in the middle of the bed which makes it nearly impossible to roll over. I wake up in pain after only a few hours every night and can never seem to get comfortable. The Dormeo cost considerably more than its competitors and truly is piece of junk. The material has simply collapsed! At least I could get a full night's sleep in my Tempur-Pedic even if we did have to keep it cold in the room!
