My husband and I have a queen size Stearns and Foster mattress which we have had for a number of years now. It is a relatively comfortable mattress and firm without being too firm.
One feature I don't like about it, though, is that when my husband tosses and turns, I feel every move on my side of the bed. Maybe that's partly because I'm such a light sleeper and it doesn't take much to disturb my sleep. Also, this mattress is deep and standard sheets will not fit it. I have to get special mattress covers that are made for a deep mattress, otherwise they won't fit.
I gave bed frame quality a zero as this is a review solely on the mattress, so that category doesn't pertain to what I am reviewing.
All in all, this is a pretty decent mattress. But considering the drawbacks I have mentioned above, when my husband and I are in the market for another mattress, I think we might decide on something else. The deepness of the mattress is not that much of a problem, but I don't like the fact that my husband's tossing and turning are so readily felt by me on the opposite side of the bed. It has held up pretty well and is still in very good shape, but I think my next mattress will be something different.
