I ordered this a week ago. It weighs 115 pounds so it definitely takes two people to bring it inside and set up. It is vacuum packed and rolled into a bag making it hard to believe that it's actually a king size mattress but it is. You can remove the outer bag but then get it on the bed before you remove the outer plastic. There are two sets of plastic, the first one is what keeps it rolled up, once it's removed it will start to expand a little but you have time to get it adjusted and in the correct position before removing the second/final plastic bag/wrap. Once it's removed there is no moving it, too heavy. It expands quickly and we only waited 8 hours before sleeping on it and it was fully expanded. Now, about the smell, yes there is a chemical smell, however I feel that some of the other reviewers were a bit dramatic. It's not that bad and with each passing hour it lessens in intensity. By the end of two days it was no longer noticeable at all. This mattress is excellent quality, and solid. I have laid on *********** beds before and I have to say this one feels just as good. I can't speak to the longevity yet since I've only had it a week, maybe that's the difference in price? Don't know. I will tell you that we purchased a "soft" mattress and it is still quite firm, it has softened a bit each night but it is still very firm. I only weigh 120 so that may have something to do with it my husband weighs 175 and says it's fine for him. It was a little too firm for my liking so I purchased a ********** 3-inch Sculpted Gel Memory Foam Mattress Topper also from Great Offer Stock and man oh man does that make a difference! It gives me the cushion and support I need for my lower back. This mattress and topper is unreal! I will tell you that with the 14 inch mattress and 3 inch topper plus mattress protector and sheets it's a good 18 inches. Make sure you have deep pocket sheets and big comforter. I'm short so I practically need a ladder to climb into bed LOL! My husband has back problems and this mattress seems to be helping. When one person moves or gets up there is very little transference of motion/movement which is nice, I'm a light sleeper. It's not bouncy at all like a spring mattress, it's solid and absorbs all impact. I can't say enough how impressed I am with this mattress and topper, best $$$ I've ever spent. I still can't believe I got it at Great Offer Stock. Who buys a mattress from Great Offer Stock.com??? I do!!! You will be pleased. I figure the mattress topper will give my mattress longer life and even if I have to buy a new topper each year, that's still way cheaper than spending $$$$ on a bed with those other guys that advertise on TV all the time. I couldn't be happier, and I am considering buying another one for our guest room.
