I was hoping to love this mattress as my husband bought the same one -- medium firm -- in the full size and his is a dream. His mattress is plush and cozy, just what I was looking for from a gel memory foam mattress. Mine is FIRM, without any of the plushness his has. We opened it up 1 day after it arrived, and it quickly puffed up to almost 14". But the memory foam is unforgiving in my mattress and now I'm stuck with it unless my husband decides he wants to swap (he finds his a tad too soft). It is only the third day of use, but I'm not hopeful it will get any softer or more forgiving. Beware buyer -- there is a bit of italics (smallish print) at the end of purchase page which indicates that this type (or their brand) of mattress "can vary in firmness'. I guess I just got unlucky.
