Sinking

The mattress, which I've only had less than 6 months, has a depression that has not recovered. It is right where my hips are. I am normal weight, (185 lbs), and there's no reason this should happen. I paid a lot of money for this mattress, and I'm going to seek a refund.

Not as firm as expected

We tried this mattress out in the store, loved the feel. When we got it delivered, my wife and I both said this ain’t as firm as the one in the store was. A little disappointing but decent mattress overall
