We bought a new firm-top mattress because our old pillowtop sagged too much, but we found the new mattress too firm- especially me, because my hips would dig into the mattress and hurt after a while. We had a 4 inch topper before, which I loved but my husband found to soft (he's a stomach sleeper), so we compromised with this 2 inch topper. Be aware that this does have a very minor minty-ish scent, which I wasn't expecting. We let it open up and breathe overnight, and neither of us noticed any scent, so that was good. It is just soft enough that my hips sink in, but my back is supported, and my husband says he likes it, too.
