    Having slept on a more expensive foam mattress bought from a mattress retailer, I swore I would never go back to a conventional spring mattress again (as most foam mattress owners can attest). I found myself having to move and being short on cash, I purchased this item after doing quite a bit of looking around for the best deal. I have lower back issues so I really took my time with this and read everything I could find. To the best of what I learned about memory foam, the higher the weight of the foam per square foot, (ie: 4lb, 5lb) the thicker the density and therefore the firmer the mattress. Since it wasn't listed, if I had to venture a guess at the weight of this foam I would have to say maybe 4lb, since it's on the soft side. Now be forwarned, what you're buying here isn't exactly the same as a tempur mattress or one of the higher priced foam models. Those are built of layers of different density foam to create a certain feel. This, to the best of my knowledge, is one solid piece of foam. That being said, the experience and feel is slightly different. And the overall feel is a little softer than layered foam mattresses (which I anticipated, and is why I chose the 12" thickness vs. the 'thinner' models offered). But let's face it, the feel might be slightly different, but so is the price tag. I've owned this mattress for about two and a half weeks. And it is EXTREMELY comfortable. I followed the instructions and let it sit and off-gas in a room with the windows open for 48 hours. There was a slight odor but either it's gone, or I've grown accustomed. Either way, it wasn't that bad. I'm a bigger guy, and I sleep like a baby on this mattress. So at roughly 20% of the price of one bought at a retailer, how can you lose? I shipped site to store and picked it up. It came rolled in plastic, squished flat...which was slid into a long drawstring bag. It basically looked like a five foot sleeping bag that fit easily into a small suv. Hope this helps. Good luck!

    Firm Foam at a Great Price

    This 12 inch Queen Mattress was available at my local store much quicker than the shipping date suggested. It was rolled into a large tube and I was able to put it in my small Toyota along with my 3 year old daughter. After opening the package (tip: hold onto the outside sack and let gravity pull the mattress down and out rather than trying to roll it off) the mattress began to expand rapidly. I noticed no unusual smell as many reported and the mattress was full size within an hour. I still let it set for a few days (the instructions suggest 48 hours) and put it on the new box-spring I’d bought elsewhere. This mattress is HUGE. We practically have to jump up into our bed. The foam is very firm (possibly too firm for many) but as a therapist specializing in back pain, I recognize that firm bedding (contrary to popular belief) is actually much better for the health for the back than squishy over-soft mattresses. We feel supported across the entire body. Finally, the ultimate test, I have already recommended this mattress to others and would buy it again without hesitation.

    This bed is fantastic, and at an unbelievable price. I've been sleeping on it for a month now, and I can't begin to tell you how great it is. When you climb into bed, its just instant comfort. There's no pressure points like a regular mattress of course, and no need to flop around trying to get in the right spot. However you want to lay, your body just fits it. I fall asleep faster since I've had this memory foam mattress! And when I wake up, I feel good! I don't feel like I've strained or stretched or had something bent wrong or prodded all night. You can wake up feeling refreshed and agile. On the old spring mattress I had before, I slept on my stomach an awful lot because it was more comfortable than all that pressure on my hips or bum while on my side or back. And while sleeping on my stomach might still be nice, I never need to! Again I'll say, there's just no need to toss and turn. However you end up laying is how you'll fall asleep. I will say, though, that this is a firm memory foam. Not super squishy like you might get with just a mattress topper. But I have heard that this firmer style is better for your back (and having scoliosis, I'm thankful for it!) and while I was a tad worried I wouldn't like it at first, I now love it and am so glad I made this purchase. One should also know that the mattress comes in something like a giant duffel bag type thing, sort of long like the old military ones. Not the easiest thing to carry, but it does have a strap for, in my case, dragging. It was so much heavier than I expected, so if you're a lady or a bit older, you might want a friend to help you. (I had to drag mine up a twisty flight of stairs to my apartment, two steps at a time, in blazing +100F Texas weather!) And once you pull out the mattress, it starts fluffing up right away. Despite the recommended 2 day fluffing/airing out time, I slept on this baby 6 hours after setting it up. It was ready enough for me. And no smell! Perhaps the plastic wrap had a smell, but it wasn't in my beautiful mattress. I paired this mattress with a suggested bed frame- the "Premier Platform Bed Frame"- and they're terrific together. (Super easy set up, too!) I wouldn't suggest putting this mattress on a box spring. Being made of foam, it has different support needs. They work very well together and I'm confident in the sturdiness and comfort they'll be providing me for many years to come.
