We've had it for four nights and so far so good. I've been sleeping on the couch for so long that it's hard to get used to a bed again.  It's a little firmer than I expected but my back isn't sore in the mornings anymore.  Hopefully, it will continue to be so.  It's not hot, even my husband says so and he's usually burning up.  Opened easily, no smell. Only reason I did 4 stars is because we've only had it a short period of time.
