This mattress topper feels like you are enveloped by a cloud or pillows.  After using it, I woke up with less back pain than before. It comes packed well and is easy to unfold.  My only issue is that it is a bit larger than my mattress, and the corners are square and do not round to match my mattress, so it does stick out a bit.  Luckily I was able to fit it under my mattress pad and sheet without too much difficulty.
