    I changed from a traditional king size mattress with attached pillow top to this mattress. I did a lot of research about the history, lineage and current memory foam manufactures. As always, you pay for what you get, so going on the low end will likely result in problems. The uppermost tiers offer incremental refinements and perhaps some curb appeal and perhaps bragging rights about brand name. The incremental cost for those features however is very high relative to the features that I feel are important like quality, function and comfort - I figure I'm buying a bed, not a Ferrarri. This bed is like a BMW. I have had this mattress for 4 months. I am extremely pleased. Here is a short summary of my experience: My research indicated that common complaints of crossover folks like me would be the curing smell of the mattress, hot or cold retention and inherent differences of bounce behavior between traditional and memory foam mattresses. My findings are that most complaints (and I looked at thousands of blogs and reviews) are not due to the brand of memory foam mattresses per se, but more to due with the general transition from traditional to memory foam mattresses. THEY ARE DIFFERENT experiences! I break softness and hardness into 2 categories: Initial entry and sleep. Initial entry is experienced when you 'hop' into bed. Traditional mattresses are like hard dry golf greens where memory foams are more like soft golf greens. In traditionals, you get the bounce boost on your knee or behind to get you into the bed (especially if your bed frame is high). On memory foam, there is no initial bounce - instead your planted appendage sinks and you ungracefully tumble into bed. So it takes a while to adjust to. Sleep softness is the feeling once you are situated to go to sleep and again is different from traditional mattresses. Hard memory foam mattresses take a little longer to comply with your shape than medium or soft. Also hards won't comply as much to your body contours as with mediums or softs. People reviews take this to mean - the bed is as hard as a rock. For those that like to sleep on their stomachs or sides like my wife I suggest getting a medium or soft. Back sleepers will like medium or hard. I compromised with a medium which my wife and I are happy with. Also be aware that traditional mattresses, unless worn out, will bounce back immediately after you roll out of a position you have been in whereas memory foam will take a minute to 'forget' you. During that time there will be a body depression which some have commented that memory foam mattresses are lump or leave big sink holes. Smell. I have a high tolerance to smells. I grew up in the 50's and 60's when air pollution made the air acidic and nearly everybody smoked all of the time. I will say that the smell was noticeable and I can see how in this day and age of health-smart over achievers people comment that the smell is bad, to way bad, to I had to call 911. The smell took about a week or two to fully go away. In the meantime I had fond memories of my polluted America childhood. Lastly my comments on the hot and cold difference between traditional and memory foam mattresses. My wife sleeps cold and I sleep very hot. My wife says that the cold component is the same in both mattresses - net neutral. I think that this mattress sleeps cooler than a traditional - for me it's a great thing. After 4 months we are really satisfied with this mattress. It has not changed its behavior one bit which is good. Some less expensive memory foam brands had complaints by this time where soft spots were starting to form. Of course I have had high end traditional mattresses over the last 30 years that have started to have sag spots after 4 months. Conclusion: I would buy this again. Overstock offered a great value and great service.

  • I wwant to sleep more

    I'm writing this review at 6:00 in the morning. I usually get up at 5:00am. After hitting the snooze button several times I finally talked myself into getting up. This mattress took some getting used to. Originally I had a very old and worn spring mattress with a foam and feather topper. I thought sleeping on a foam mattress was going to be similar, but it's not. This mattress is very firm when you first lie ontop of it. The first couple of nights were so so, but I read that it would take some getting used to which I totally agree with now. There was no smell to the mattress and it expanded to it's full size quite quickly. After the third night I slept through the whole night and didn't wake once. I sleep so soundly and deeply that I crave more time in bed. I don't feel the mattress move at all and I don't adjust or turn very much at night either any more. I went out on a limb when I got this mattress and I am so glad that I did!

    • How did the color on site compare with the actual product? slightly different, but didn't matter
  • Excellent Choice after much research!

    I researched a very long time and anywhere I could get information before finally moving forward with the purchase of this bed. The background for our story was my husband had been sleeping on an air mattress and eventually the couch because he has lipomas on his back that cause him great discomfort. We had been on top of the line plush, pillowtop and memory foam toppers but the springs still were an issue. Long story short; I was afraid being a stomach/side sleeper I would suffer back issues but was willing to try for his sake and I am grateful I too have had no issue. For the first night in over a year my husband and I were able to sleep in the same bed and he woke up with no back ache whatsoever! He fell alseep in minutes. Usually on any of our other beds 4 hrs was the longest he could stand. The quality of the bed was wonderful! The smell was minimal and did not last. It was full size within a few hours. Shipping was great! inexpensive and on time. I have already recommended this to others. I don't feel like there is a heat issue, my topper felt warmer to me. I read so many reviews but the one thing I am glad I read was the medium firmness. It's perfect. Too soft would have hurt my back. Having read the reviews of too firm being compared to a rock didn't sound appealing either. Not having a lot of money to hit or miss with made it a little scary to 'blindly order online' but I am SO grateful for the people who took the time to share and for those reviews to help me find the right bed for our family. It really is worth it! I do really love love love this mattress and have shown it off as well as tell everyone about it. The picture they use I believe is the next one up. (14 inch maybe?) but it is still beautiful and well made.

    I researched memory foam mattresses for several months before purchasing this one. After the first night of sleeping on this mattress I am extremely satisfied with my purchase. I own a Tempurpedic Cloud Supreme for my home bed but could not justify purchasing one for a vacation home. But after sleeping on a memory foam mattress for the last 5 years my husband and I couldn't sleep together on an inner spring mattress. I can honestly say this mattress compares to the expensive Tempurpedic brand. I just hope it will hold up as well.

  • Love it!

    Honestly, I purchased this mattress to change from a queen size to a King size bed because sharing our sleeping quarters with three dogs and 2 cats was disrupting our rest. Obviously this was a more logical choice than banishing the critters to the floor :). So glad I did! The mattress is very comfortable and doesn't require a box spring. It minimizes any movement from other sleepers, so no one's sleep is disrupted. The only possible drawback is that is seems to be a bit warmer than other mattresses (even without the critters or a husband). Not enough of an issue that I would lower the rating. I was surprised when it arrived all rolled up in a giant compressed bundle (and very quickly at that!). I wasn't sure I had made the right decision. But once opened, it puffed up and was completely normal. I will be getting another one for the living quarters in our horse trailer so I can really be a happy camper!

  • Best sleep ever!

    I bought this mattress for a guest bed. But I had to try it-and it is so comfortable that I switched it out with mine. Wow-I am a side sleeper-and it is nice to wake up without a nerve dead arm or shoulder pain. For the price-it is a great deal and I don't think you'll be disappointed!

  • Had potential

    we have owned this mattress for a year now. When we first received it, I loved it and found it to be very comfortable. I really liked how it contoured my body. I am a bodybuilder and often get very sore form workouts. I would look forward to lying down to get a good nights sleep. Rest is very important. After a year, my side of the bed has a divot. It no longer contours to my body it actually causes my pelvis to rotate downward. I am having pain in my lower back an hips because of it. I go to the chiropractor as well as get massages. The pain goes away. I will sleep on the floor even and the pain is gone. As soon as I sleep in the bed. The pain comes right back. I am not a "big" guy by any means. Short at 5'6" but I am a solid 195lbs. Still, it has been a year and the bed should have lasted longer. It is impossible to lay on my stomach as well due to the indent. The memory foam seems to have lost its memory.

  • Thankful for this purchase!

    This is my first memory foam mattress. It's also the first matress purchase I've made online. I was very nervous about buying this mattress without laying on it first, but I am extremely happy with my purchase. I took it out of the bag and let it lay in a spare bedroom for 4 days while waiting on my frame to arrive. Once I got everything together and set up in my room, I laid on the mattress and realized how comfortable it really is. It's firm enough to give you good support, but soft enough that you are comfortable. I would definitely suggest purchasing this mattress.
