Likely not the best quality topper you'll find, but quite adequate.   Directions suggest you allow 72 hours to fully fluff.  After  4 days I still have areas that are not as fluffy as others.  I have doubts this would fit with much room in my large capacity  dryer, let alone give it any space to fluff.   It does fit my king mattress well, the straps do keep it in place and it is very comfortable.  There is no crinkling or noise.   It's obvious that there is additional height to the mattress and I believe it may be a bit cooler than the mattress has proven to be in the past.  It had a slight chemical odor upon opening, but that dissipated pretty quickly.  All in all, not a bad purchase.
