GREAT mattress at an unbelievable price, but it's definitely more of a medium firmness with a plush top.  I like super firm, so this would definitely not work for me, but my son loves it, and he is going to be the one sleeping on it.  The mattress decompressed in no time, with minimal smell.  It appears to be VERY well made, and I can't see any points at which the construction would fail.  The quilted top is really nice, and it has detailing on it that makes it look far more expensive than it was.  I'm really impressed with this mattress and I can't believe I found a full size, 11-inch mattress for under $300.  If you like firm or super firm, this would NOT be the mattress for you, but if you like it a little more plush and more of a medium firmness, you will be hard pressed to find a mattress that looks and feels this nice for this kind of price. We are very happy with it.
