My husband and I just bought a new bed yesterday -- after testing out countless variations on this theme. I kept making up lyrics to a song a friend from high school used to sing about a "Beautyrest tester." So this morning I Googled "Beautyrest tester" and this is THE ONLY PAGE WHICH CAME UP. I am, quite frankly, both grateful to you that I'm not the only one who remembers this ditty and disappointed that there isn't a YouTube video of someone singing some variant.

...and I'd have to say that I enjoyed virtually meeting folks with the same twisted sense of humor. Crestfallen. Tee hee!
