    Customer review by fytnirshman

    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

    Customer review by DocereCraft

    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.

    Customer review by Ray1997

    Ok so I had to give myself a good amount of use time before I gave this mattress any kind of review. (I purchased this mattress in October of 2012) Buying before trying is indeed a blind gamble but this model exceeded my expectations. To start when I looked to buy a new mattress I was coming off being impressed with having slept on the high end brand we all know (TP). Before taking the plunge I literally took about a month in researching, reading reviews and learning about memory foam. After that I made probably one of the best purchases ever. I am 5'11 about 290. Heavy but not flabby heavy. I lift and have broad shoulders and do indeed have heavy bones. So that said after about a year I could not be any happier and pleased with this mattress. If you're looking for a firm bed this is what you want, with a catch. Given that the memory foam is true viscoelastic memory foam it is governed by the air temp. Meaning it will be firmer or softer based on your room temp. the colder the room the much firmer it is, the warmer the more soft. It does not however feel plush even when the room is warm. I would honestly say it could compare with the Allura. After a year of use as a daily sleeper the bed still has it's comfort and support with no apparent sinking in (I rotate every 45-60 days) As far as heat it is a tad hot but it's nothing a ceiling fan or ac can't help with. I'd recommend a mattress cover for moisture if you do sweat. I sleep all over the place #side, back, stomach) and it's been good no matter the position. The best sleep I had was last night as the bed was really firm since it was a cool night and breeze coming in to the room put it at it's peak firmness. It slowly softened as I laid in it and fell asleep. If you're in the market for a good mattress at a really good price then look no further. This has the firmness and comfort one would need if back issues are a problem. Delivery was as advertised and set up was easy. I will say smell was not noticeable and dissipated after a day or so in a well ventilated room Tip: even though it expands to its 12" height after about an hour give it the 48 hour wait period. This allows the memory foam to develop and expand evenly.
