This is finally the quality dog bed I've been looking for.  The memory foam base seems to be the real deal, and the construction is impressive.  The other dog beds I've bought (which weren't cheap!) seemed to have been made with the intent of ripping off pet owners by cutting corners, resulting in the support going flat and seams separating within mere weeks of use.  I'm impressed with this bed, and will be buying another one for our other dog, as well as an extra for our living area.
