I've been considering purchasing a Tempur-Pedic bed/mattress, but I would like to get some opinions before spending the money. The price is pretty expensive, at $2,600 for the Deluxe mattress and another $500 for the foundation (king size). If you have a Tempur Pedic, I'd be curious if you bought the foundation or just used your old box spring. Also, if you would give your opinion on the quality of sleep you found with the TP bed. I'm a side sleeper, so I get sore throughout the night and have to change sides frequently. It's a steep price, but when you consider the amount of time you spend in bed, and the effect that the quality of your sleep is. I have a newer bed, which is only 1.5 yrs, but I'm just not happy with it any longer. Thanks for any feedback.
