Very timely post---I just bought a really wonderful mattress pad/topper from AMZ----but I ordered the wrong size!!! I need a full and ordered a queen, so it hangs over by a few inches. It was packaged in a hermetically sealed bag so no way could I get it back into the shape. I requested a return---would have cost me $11, not bad, but I decided to keep it as the length is fine just a few inches over hang on one side. It would have been free to return to an Amz store however that was not anywhere near where I live.
