We received our bed quickly, and the price for a cal king was unreal. I admit my husband and I were skeptical, but so far we have been very pleased. It was packaged well, and it is very rolled up and sealed tightly. But once opened, it does expand quickly to almost it's original size, then continues to expand over the next day. The smell was not that bad. I mean if you put your nose right up to it, yes it does have a chemical odor, but once the sheets were on, could not smell it, And it certainly did not stink up the whole room. As for comfort, we have also been impressed. We have it on the floor now, because we had to take down our old bed (that was a queen) to let this one open up and expand. And we plan on building a platform bed for it in the next day. So we have had the mattress on the floor, sleeping on it. And even on the floor, it is still very comfortable, The quality seems to be good also. We ended up ordering a 2inch memory foam topper for it. The top is soft, but we personally want just a little more cushion on top. But honestly, could of done without it for now. We did get the ultimate approval after the first night when my 10 yr old yorkie got on it and slept all night, she hardly moved! That was unusual for her. We also noticed we tossed and turned a lot less. This mattress is still new to us, so cannot speak for holding up, but so far we are happy with our decision!
