This is a great topper.  I received as scheduled with no problems.  I opened it and let it set out for about 48 hours.  We put it in on top of the mattress in our RV because the mattress isn't of the best quality and it made a world of difference.  I also ordered a nice, padded waterproof mattress pad to put over the top of it, then the sheets, and now the bed is amazing and protected in case one of my grandchildren has an accident!
