Love it.. I have a king pillow top.. I learned my lesson I will never ever buy a pillow top again..They sink in the middle.. I bought this to help with the problems with the mattress.. I did have to put the pillow top on the bottom..For more firmness. Everyone that comes over freaks on this .. They love my bed..LOL.. Any way It is thick. I wish I had went down in thickness. But it is wonderful..
