My loss is your gain!  Bought this last month to help "fix" a mattress that was too firm, but ultimately decided to buy a new mattress instead.  I figured I'd return this topper when it arrived, but it's not a returnable item. Whoops...

Retails for $469, score yourself an amazing deal on this brand new in box item!  I never opened the box; it's straight from Tempur-Pedic!
