The product came wrapped just as it said, with very little odor of packing materials which some people had mentioned. It expanded VERY fast and was ready to lie on within 90 seconds. I have honesty had the best sleep of the last ten years on this mattress. Now, my ONLY gripe is something I was unaware of when I purchased this mattress: It is hot. I mean it retains body heat. I give off a lot of body heat and it all gets channeled into the mattress, so I constantly need to have a fan or the AC on to stay cool..I haven't had it through a winter yet, so maybe that's a plus, but in July/August, a fan is a must. All in all, great mattress and immensely comfortable for me. I chose the medium and it was pretty firm.
