Bests & Worsts Reviews from Amazon

It seems that I am in the minority here about how I feel about this mattress. I ordered a queen size back in July and within just a few weeks of sleeping on it, there was a pretty big dip in it. I tried sleeping on the other side of the mattress and same thing. Dips appeared there within a couple of weeks. After that, I flipped the mattress and... same thing again, only this time faster. Dip appeared after one sole night of sleeping on it. It's fully supported underneath so that's not the problem. I waited the recommended amount of time - and then some - before sleeping on it. And I am a 5'6" tall, 130 lb female, so I don't believe my weight is the problem for causing a dip in this mattress either. But since everyone else seems to love it, I'm thinking that maybe I just ended up with a dud? Possible. But either way, I'm not pleased with this mattress, and I wouldn't buy again. Nor would I recommend it to anyone.
