My Greatest Ever Feat of Strength!

So I guess technically it was a combined greatest ever feat of both strength and stupidity... I just moved my new king size mattress up 3 flights of stairs!  The closest I can think the relate the experience to is if I was a firefighter rescuing the Guinness Book of World Records Fattest Man from eminent danger.  There were times when I am sure passersby thought I was being eaten by it.  No sliding that bad boy, it molded right to every step and crack in the wall I hit, but I was determined; success was mine!  Now it sits conquered, sulking and taking up the majority of my living room.  The truck driver who left it on the driveway stayed around a few minutes, I think long enough to be sure I wouldn't become trapped under it 'with only a cell phone, a lighter and 90 minutes of oxygen';)  Anyway, I need to get sails, I mean sheets, for it and I'll let you know how it is!  I hope over the next 30 years (warranty) it will pay back some of the life that was certainly sucked out of me by moving it.
