    • We love it

      It took some getting used to as we had a waterbed for over 20 years. I had a horrible neck ache for a while because of the different surface my pillow was on. I had to buy a new pillow. I did not notice any odd smell.

    • Very Firm

      Overstock is great. Quick delivery. Arrived rolled, so easy to transport to upstairs. It is a firm bed. I wake up sore everyday. Looking to replace within a year.

    • Not consistent.

      I bought one years ago and still use it. It's 5star. I just ordered a new one for a different bed. First it was lost in the mail somewhere then I had to eventually order a replacement. When it eventually came I discovered it really dips on one side. You would roll off the bed. Like the foam layers were squished too much or something. It's too much of a pain so I tell my guests to try to sleep on the other half of the bed.

    • Best Deal in 30 years!

      When it came, it was rolled up. I thought I got ripped off! After letting it sit open for a few hours, it turned into, well, my heaven! Very responsive to my body weight (145lbs). In the mornings, I don't want to get out of it! That comfortable, it is! In the evenings, I prefer to surf on the laptop, laying on the bed, rather than lounge by my fireplace and do the same! Now, speaking objectively, in comparison to spring mattresses, this trumps them all. Pillow top and all..had them, no comparison. If you've had the thin version of the memory foam mattress and found yourself hitting a hard spot (ie. the platform of your bed frame), this I assure you, will not do that. If you've purchased a memory foam that ends up feeling like a hammock by the morning time, this again, does not do that. Truly identical to the memory foam mattresses I have slept in, at 5-6 star hotel suites over my travels around the, more affluent, countries. Excellent for side sleepers! If you prefer laying on your back, because I'm both, you will need a Goose feather or memory foam pillow of your liking. Final thought: The next level would be sleeping on a cloud of air with air jets pressing on your 5 pressure points.

    • About time

      I spent enough time studying this product to qualify for a college credit just because for me this was a lot of money and I wanted to be sure I was making the best decision. I read over 350 reviews on several sites including this one before making my decision. It was my first purchase on OS and will not be my last. I have never slept so good. The past few years I never slept more than an hour or 2 without waking up in pain in my shoulder, hip, back and neck. This mattress cradles your pressure points and eliminates almost all my pain. I sleep as much as 5 and 6 hours without waking up. Firmness is perfect and I cannot believe how easy it was to set up. It was a few nights before I realized there is absolutely no noise, no creaking, no sqeaking nothing. I told my sister and she ordered one the next day from OS. A co worker asked me if OS was paying me to be a spokesperson for this mattress because I can't stop talking about how amazing it is. Also, it was by far the best price for the quality, trust me, I did my research. When I save some more money I want to buy a platform bed to put the mattress on. I bought the metal frame from OS also and I'm very happy with that quality also. Treat yourself to the best nights sleep you will ever have.

    • Best night's sleep

      We've had this mattress for several weeks at least and had to leave it rolled up because we were moving in to our new house. Though we planned to paint our bedroom before we unrolled it, we got too far in setting up the bed frame and ran out of floor space in the room and had to put the mattress somewhere. So we unrolled it. A couple of hours later, we leaned on the bed to pick something up and we were amazed at how fantastically soft it was. We then decided we wouldn't spend another night sleeping in a bed that wasn't this one. It was the best night's sleep we've had in months. Not only was it soft and supportive, but I don't know how many times my husband rolled around in his sleep. That alone was worth buying the bed. We picked out a very simple platform bed, without a headboard or footboard, because we plan to make our own out of some old church doors. I also noticed that some people complained in reviews about how hot the mattress could get while sleeping. I purchased a mattress cover and that, I believe, helped keep it cooler. Though extra body heat isn't a bad thing since we live in a snowy state and are in the midst of winter. Hopefully it won't be bad in the summer.

    • Worth the money

      I was a little skeptical of buying a bed online that I could not actually lay on first to test, but after reading the reviews I took a shot and am glad I did. My ex-gf had a tempur-pedic mattress that was approximately the same weight and size but she paid around $2500 for, so I was hoping this mattress was similar to that. It was. At 1/5 the cost. First, the mattress comes rolled up lengthwise, like a carpet, but is shrink-wrapped. The UPS label had a weight (queen size) and it said 90 lbs. So make sure you have some help getting it into your place if you are not able-bodied. Second, make sure you have some kind of foundation for the thing, as it does not come with anything but the mattress. My ex had hers on a piece of plywood which was on a bedframe and it worked fine, I simply threw it on my existing boxspring. I read some reviews about the chemical smell, which there was some, but it was not pungent like some reviews I have read on here. I let it air out for about 4 hours and it seemed fine. Also, I bought a vinyl mattress protector from Bed, Bath & Beyond for about $20, and wrapped the mattress up in it so as to keep it new, plus put my existing mattress pad over that. Being 6'6" and close to 275 lbs, it is legitimately one of the most comfortable mattresses I have ever slept on, and although I haven't owned it that long, I will update my review if it starts to sag or dip. Google "overstock coupon code" and look for a discount before you buy it, I saved an additional 10% by typing a code in I found online. Anyways, for the money, I would suggest this to anyone looking for a great night's sleep at a bargain price.

    • Good night sleep

      I bought this because of my back I'm 275lbs. and would wake up with a lower back pain all the time with my other name brand mattress. Now that I have tried this for two weeks my back pain is almost gone and I'm sleeping all night long, I would highly recommend this to anyone. I received this seven day's after I ordered it, there was no smell when I opened it but I let it sit out for a day before using it. For the money you just can't go wrong.

    • What do you put this mattress on? Doesn't it need a boxspring? Or some kind of platform so that it has proper support and so that isn't too short/close to the ground?

      • Hello kjinterior, this item does not include a box spring. This item can be used with a platform mattress with a box spring. Thank you for shopping with us.

    • What is the IDL --indentation load deflection units for this mattress?

      • Hi Gmench, thank you for your inquiry! The IDL for this mattress is 33 bottom, 25 middle, and 12 top. Hope this helps, have a great day!

    • Can you use an electric heated throw with this mattress?

      • Hi lsolrak, you would be ok if you used a heated throw with this mattress. This product does not have any resrtictions for heated blankets. Thanks for shopping with us.

      • Yes, I use a down bedcover. The foam will become the temperature of the room and at times its like sleeping in a water bed with no heat the mattress seems to suck heat from your body. You may want to create insulation between you and the mattress. Unless the electric cover is under your body you'll continue to have the same problem. Kelly

      • We are unable to disclose the manufacturer of some of our products; however, stands behind every product we sell. When necessary we can contact suppliers if a product issue arises.

    • Is this foam closed or open cell?

    • I am looking at this matresss and says meduim I am interested to see a soft matress in this product. Are there soft memory foam matresses

      • We have many soft memory foam matresses but not in that exact style. Please feel free to browse for them.

    • What are the shipping dimensions?

      • The shipping box dimensions are 22 inches high by 22 inches wide by 65 inches long.

    • Will regular queen sized sheets fit this mattress...or would I need to get deep pocket sheets? if so, what size

      • You would need 14-inch deep-pocket sheets for this mattress.

      • I have a 14-in sheet set for this bed, and a 15-in sheet set. The 15-in definitely fits better.

    • many of the reviews seem to say to get either the soft or the medium support and to stay away from the firm support version of this bed-- is there a difference in firmness between this 14 inch and the 11inch versions? I am looking for soft/medium support...

      • With memory foam mattresses, the firmness is determined by the foam density rather than the actual thickness of the mattress. Both the 11-inch and 14-inch versions of this mattress use a 3-pound density memory foam for medium firmness. The difference in the two is that the 14-inch mattress has an additional 3-inch memory foam topper that gives added comfort.

    • I'm very interested in purchasing this mattress, but i can't seem to find the dimensions.. i have the ikea malm queen bedframe which dimensions are as follows: Length: 83 7/8

      • Length: 83 7/8 " Width: 66 1/2 " got cut off ^^

      • please delete, i found the answer. apologies.

    • Is there a mattress cover like the one that came with this mattress (that fits fully around the mattress and zips up) in Full size?

      • Yes, we do have full size covers available; there are several different kinds to choose from. They can be found if you search "full size mattress cover".

    • Where is this bed made?

    • Do you need a box spring to set it on?

      • It does depend on the bed frame you are using.

      • If you are using a frame that does not offer sufficient support throughout the bottom part (such as the type of frame that a boxspring typically sits on) then, yes, you will need a box spring. However, if you have a platform bed or platform base with plenty of support you will not need a box spring. Keep in mind that if you live in an area with high humidity, you may want to put a simple rug mat (not an actual rug, but the mats that go underneath to prevent slippage) under the mattress to prevent mold on platform beds that do not have much ventilation where the mattress sits. If there is no room to breathe, moisture can get trapped between the platform and the mattress and cause mold. If you live in a dry climate you should be fine. I do not know if the cover that comes with this mattress is sufficient to prevent mold on a platform bed.

    • Is there an equivalent of this mattress in Full size?

      • Unfortunately, we were unable to locate the exact item in a full-size. We apologize for the inconvenience.

    • How much does this mattress weigh?

      • It weighs about 90lbs and comes rolled up in a cloth sack (similar to the kind a sleeping bag is put in) held tight with two strips of clear plastic, inside is another protective layer of some sort of white woven plastic material, and then a clear plastic bag around the mattress. The mattress is already placed inside of the mattress cover so you won't have to put it on yourself. If you have to get it through a narrow space I recommend rolling it end over end (while still in the sack) to get it in place. This method proved much faster and easier than trying to drag it in the sack (which had no handles and the sack fabric ripped).

    • Does this mattress have to be "flipped" from time to time?

    • What is the 3" of "zoned comfort support layer" between the memory foam & the base foam?

      • This middle layer has three sections, one to support the head, one to support the feet, and a firmer middle layer to support the middle of the body. This is a 1.75 pound to two pound density firmness and is a non-memory foam material.
