I bought my Tempurpedic bed from Brookstone. I was greeted warmly at the door by one of their salespeople, and I was allowed to lay down on the beds and try out which one suited by taste (and back problems). I was asked questions, and the woman wasn't pushy in making me buy a bed right then and there.
I'm so used to my bed now, that when I go on vacation, I really miss my bed. Even those sleep number beds are dogs compared to this thing. Really great.
