The product description that accompanies this item is inaccurate. More specifically the word mattress.  Nowhere in the numerous paragraphs describing the item does it say mattress topper. Time and time again it mentions mattress and although it was confusing I chose to go with the word mattress hoping that there was no way that the company wouldn't notice the description mistake and that it was actually a mattress like they said.  It is really a mattress topper.
