I was very nervous about this purchase. Needing a low profile mattress for my mother who is in assisted living. After reading, and reading, and reading reviews of a number of mattresses, I finally decided upon this particular mattress. The hardest part then became deciding on medium firm or firm. I was afraid of it being too soft and causing her back pain with not enough support. I finally decided upon the firm. It is just that. Very firm. When you first lay on it, it is extremely firm, but then you can feel the softness of the memory foam giving and it is quite comfortable. If I had it to do over, I would probably order the medium firm, but I am still happy with the purchase. We removed the mattress from the packaging and let it expand for about 36 hours before we placed it on the bed. Don't be alarmed when you first see it. It looks a bit flat and the case that cover it looks big. But, when we came back to the mattress after the 36 hours, it was completely filled out and we were amazed. There is a little bit of a smell, but it is nothing that you wouldn't expect any time you open something new. The smell was gone by the time we placed the mattress on the bed....so don't let others' comments about that deter you from this. We were very happy with the purchase.
