Did this topic, by any chance, come about by that new "Ask me about my tempur-pedic" ad?
I just saw this commercial last night, and then I recalled seeing this thread in passing a few days ago; it seems both this topic and the ad's aim are the same, detailing what the commercial was bartering to me: find out about tempur-pedic from your (rich, comfy, loafer-wearing) friends' experience with their own.
