Well...I got this for my guest bedroom and after opening it, waiting the 48 hours for it to expand, and testing it -- I took it for my own bed!  Packaged very well and easy to open.  Expanded well after waiting as directed.  Decided to test on my own bed and it was a great sleep.  Just enough to cushion my body without being too soft and it didn't feel hot during the night.  My cat loves it too.  I haven't used the mattress pad that long yet so far it's remained fluffy and hasn't conformed or smashed to a shape.  No odor or unpleasant smell.  Very pleased.
