This is a very nice mattress, it had no smell, shipped fast and expanded to the correct and full size right away, but we do feel it's a bit soft. So many reviews said this mattress is firm. I would not call this firm in any way, it's more like a marshmallow with some support--and we agree the edges are not super supportive. We may trade this in for the firm model of the same mattress. Overall the quality and mattress are very good and we could probably learn to love the softness, but if you want firm support this is def not it.
