Bests & Worsts Reviews from Amazon

Ok. so I read TONS of the reviews and was left more confused than when I started. Everything from 'too soft' to 'really firm'. So here is a review that I hope helps someone else. We had a tempurpedic which we hated...felt like sleeping in a lump of clay. Then we got a sleep number which we are pretty happy with. My sleep number is between 50-60, but usually 55. We bought this mattress for a full bed in our guest room. You need to put it on a box spring, IMO. The sides are fine...no problem 'slipping off the edge' as others have mentioned. If it is shorter than a 'normal' mattress, I couldn't tell...fit on top of our box spring from a regular mattress set just fine. I do not find it too soft or really firm. It is firm yet 'cushy' with a nice feel to it. Is it the greatest mattress ever? No, but I don't know how anyone could expect any more from a mattress for this price!! I love that it was shipped to my door in a box that we were able to manage up the stairs and it was cool how well it 'puffed up' and how quickly it did so. One word of caution...It is rolled and wrapped in plastic and then put in the cardboard box for shipping. Be REALLY careful when opening the end or you will accidentally cut the mattress. We used a box cutter and cut open a tiny corner, then pulled and tore the cardboard till we could see inside enough to avoid cutting the mattress.
