I have had a tempur-pedic for 13 years and over the past few months I noticed I wasn't sleeping well and thought it was due to stress. Long story short at I read that tempur-pedic's are good for 10 - 12 years, which made me wonder if that was the issue. I am now 60 days into the new tempur-pedic that we bought and I sleep great! They are a lot of money but you can't get back the night you don't sleep. Highly recommended.
