The only thing Plush about this mattress is the first 3/4 of an inch, after that this mattress (at least mine is) should be rated as firm.  We let it expand as directed for 72 hours before use and my wife really hates it.  I find it very firm as well.  There is no cheap way to return this so this it expanded over 6 times its original shipping size. We then spent more money and bought a 3 inch mattress top from Wayfair, but haven't received it yet.  If this doesn't do the trick it's going in the garbage.  I never bought a mattress on line before and never will again.  A few reviews stated it was firmer than a plush but we wanted a mattress slightly firmer than a plush but not as firm as a sheet of plywood as ours seems to be.  I am 6 feet tall and 230lbs and only make a slight dent in the mattress.  Buyer be ware, I blew this purchase.
