The reviews were correct. Unrolling this baby was a challenge. It does have a smell, but after a week, it goes away. Very comfortable. I wanted to postpone the purchase of a new mattress, and this is doing the trick for the time being. I've had it a month and I'm satisfied. My only gripe is that there are two spots where it didn't expand to full size. It's still mushed, and I fear that it will always be that way in those spots. For a single sleeper, it's not a big deal, but if you have to share your bed, the person on the mushed sided gets the short end of the stick.
