    ITEM#: 13811864

    Enjoy a better night's sleep on the king-size memory foam mattress. Designed from memory foam, the therapeutic mattress distributes your body weight evenly and prevents discomfort. The box spring foam mattress provides stability and relives painful pressure points by improving circulation. With an eight-inch layer, this mattress guarantees stability and firmness while you are sleeping.

    • Assembled in the USA
    • 2-inch memory foam breathable comfort layer
    • 6-inch premium base layer for stability
    • Distributes body weight better than traditional inner spring
    • Relieves painful pressure points
    • Holds its shape, no flipping or rotating required
    • Foam made in the USA
    • Use with your existing box spring and frame, or platform bed (with no box spring)
    • Eliminates motion transfer between you and your partner
    • Improves circulation
    • Dimensions: 8 inches high x 76 inches wide x 80 inches long

    Memory Foam Tips:
    • Remove from packaging within 72 hours of receipt to maximize memory foam expansion
    • This product arrives tightly packed in a box sized to be portable; once you unwrap it, you can sleep on it the same night, although it may take 48 hours to return fully to its original shape.
    • Memory foam is inherently comfortable and supportive, no matter how firm it feels; similar items can vary in firmness due to the nature of the foam
    • Product is vacuum sealed at the factory for efficient shipping; vacuum sealing sometimes traps odors, but once opened, a few hours of airing will usually remove the odor
    • Due to machine-cutting manufacturing processes, there may be slight variances in the dimensions of this product.

    Due to the nature of Memory Foam the firmness level of every item is unique. Please be advised that even similar products may produce different firmness results.

    Once opened this product is non-returnable

      Owned it for over 2 yr's. Still in perfect shape. Sleeps like a dream, never know when each turn over during the night. Would recommend it to anyone. Still worth more than we paid for it.

      Great Mattress. I have owned the queen size for many years. Opens up right out of the box. Love it.

    • Great mattress, great value
      Verified Purchase

      The mattress came rolled up and vacuum sealed. We took it out of the box and it expanded to it's normal size pretty quickly. We let it expand and off-gas overnight, then swapped out the old mattress the next day. It is a bit firm, so if you prefer a soft mattress you would need to have a softer foam top / eggshell type of thing. I happen to like the firmness, I have not slept better!

    • Great bed, can't beat the price
      Verified Purchase

      We were looking at standard King mattresses but decided to see if we could find something cheaper on the internet to get by until we could get one of the fancy, expensive mattresses. I found this one and for the price, I couldn't pass on taking a gamble. I was worried because I never liked the memory foam I've tried in the stores. I was also worried about the quality because of the super low price. It's been about a month and we are in L O V E with this bed. Shipping said it would be 3 days but ended up taking about 5. Not a big deal. It is about 110lbs shipped but my girl friend and I had no troubles carrying up the stairs. Unpacking and setting up the bed was a breeze. Just cut open the plastic, position on the bed, and watch the mattress expand. It did have a slight odor as mentioned in all the other posts and it took a couple days to air out. We started sleeping on it the same night. I am so happy with this mattress. I'm in my early 30's and have chronic back and hip pain. It's amazing what a new mattress can do! My back feels great and I feel more energized in the mornings. My girl friend works odd hours and it is really nice not to wake each other up when we get up and down. Now we just have to see how this mattress stands the test of time. I am satisfied with the quality and don't anticipate that I will have to worry about a new mattress for years to come. I highly recommend this product!

    • Warning: Very Firm
      Verified Purchase

      While the matress seems pretty high quality (especially for the low price), it's just too firm for us. We gave it a week to make sure it had expanded to it's full thickness, etc. I can't imagine how so many people find it comfortable. I understand that different people with different bodies have different tastes, but it seems to go beyond that, this thing is hard!. We're pretty light, like 120 and 150 lbs. and maybe that makes a difference. We have a smaller inexpensive memory foam matress we bought a few years ago and we really like it. We were hoping to get something similar with this king size matress. I would have given it a higher rating but feel Overstock should have put that it's very firm. Since we can't return it, we're now trying out different matress toppers to suppliment.

    • The best mattress!
      Verified Purchase

      We took a risk by ordering a mattress online without testing it out first, but the reviews and the price were so great that we went for it. The bed is perfect! We wanted a memory foam mattress and this is just as good as the ones we've slept on at hotels. It's 8 inches thick, so it sits pretty level with the top of our platform bed (because we don't have a boxspring), so I may have wished we got a 10" version because it makes getting out of bed a little harder, but just measure and see if you'd have the same problem. It was delivered in a large box (it was vacuum sealed so it was easy to maneuver) and we just unfolded it on top of our bed. A few hours later it was fully expanded. We slept on it the next night and when you first lay down it's really firm, but then you sink into it ever so slightly. I would say this is the best bed if you like to sleep on a firmer surface, but you may not like it as much if you're into the plush thing.

    • Great bed
      Verified Purchase

      My wife and I bought this bed for Christmas and we love it!! It was very firm out of the box so my wife was unsure if she'd like it, but after about a week it began to break-in (soften) and now we are both getting better sleeps than we ever have. Our back pain is a thing of the past. FYI - there is a bit of an odor after opening it, which took about 1 day to dissipate. I'd suggest letting it air out in a garage if at all possible. The odor wasn't too overpowering that we couldn't sleep however. Also, I've read that some people feel the mattress is too hot, but my wife and I have not found this to be true. It's possible that because it is winter it doesn't "seem" hot, but I just thought I'd pass along our experience. In addition, in case anyone is wondering, we put this mattress directly on a new metal frame that we also purchased at Christmastime ($99), and the setup has been perfect. Without the bouncy box spring and mattress my wife and I can get in and out of bed without waking the other one up. It's been great!! I strongly recommend this bed to anyone looking for a comfortable, inexpensive, alternative to a "normal" setup or to the higher priced memory foam mattresses that are out there. For the price, comfort level, and ease of setup this mattress can't be beat!!

    • The best mattress ever

      This mattress is the best ever! I had been looking for a memory foam mattress for months, even testing out the expensive mattresses in various stores. I found this one on Overstock for thousands less than those I had tested. I must say, I couldn't be happier. I was a little hesitant not knowing if it would fully expand coming out of the box. However, it came out of the box easily and fully expanded within minutes. I was never a great sleeper, waking up often throughout the night. I also suffered from aches and pains after waking. Since receiving this mattress, I've never slept better & my pain is gone. I literally sleep like a baby. My husband (who was never a great sleeper either) also can't get over how comfortable this mattress is. He too is getting his best sleep ever. I really can't say enough about how much we love this mattress. I would highly recommend it to anyone looking for a great memory foam mattress & a fantastic price.

    Questions & Answers

    • Why did you choose this product?

      Read more Read less
    • Hi I live where the winters are cold and use an electric blanket, will this bed stay cool even with the electric blanket?

      • Probably not. I use a down comforter with it during cooler months....and the temperature is just fine; an electric blanket may be too warm.

      • Hello nancy177! It is not recommend using an electric blanket or heating pad with this mattress. Due to the temperature-sensitivity of the material, adding high heat can hinder its ability to react to your body temperature and conform to your body shape. Thanks for shopping with us! -Amanda P

    • Can I put the bodipedic 3 inch topper on top of the 8 inch mattress?

      • Don't think you would need it. It's great as is. You could of course, perhaps if looking for more softness.

    • Are there any harmful chemicals used to make this mattress? Such as Formaldehyde (sometimes present in glue), triclosan (antibacterial), pentaBDE (flame retardant)?

      • Hello sd0yle, thank you for your inquiry! we were able to confirm that this item does not have any harmful chemicals. There is no Formaldehyde, triclosan or pentaBDE present in this mattresses. The only flame retardant is in the mattress cover – which is a Modacrylic Flame retardant or an inherent fiber that is naturally Fire resistant. I hope this helps. Happy shopping!

    • If I get this mattress with the "recommended" DuraBed Steel Foldable Platform can I simply just place mattress on the Platform? Or do I need a box spring?

      • Hello oregondaddy, you will not need a box spring. You are going to love this! I just got my first memory foam mattress and they are so comfortable! Have a great day!

    • If this is placed directly on a platform bed, will the memory foam sink into the slats? How can this be best optimized with a platform bed? Can I place a bed rug under the memory foam on a platform bed?

      • Hello ariedulan, Thank you for your inquiry! You can either put it on a platform bed by itself or if your would like you can use a box spring or a bed rug. Any of these options would work with this mattress. I hope this helps. Happy shopping.

      • We have ours on a conventional bed with slats, but then we put two pieces of plywood over the slats so that it wouldn't "sink" between them. It's perfect!

    • what is the size package? including box size and weight when shipping?Is this item in a box?

      • Hello chucknorrisjamaica, The box size is Height: 39 Width: 19 Length: 23 . The weight is 90 pounds. Have a great day!

    • it it a firmer bed

      • Thank you for shopping with us timeout01. Reading the first 20 review on our page, there were quite a few comments about the firmness of the mattress. We do post that your mattress will be unique. I have this company’s mattress pad and it has lasted over 3 years and really enhanced my bed. Have a good day!

    • Can this be used with a box spring?

    • Can you put it on top of a sleep number bed?

      • Why would you want to? Do you just mean the sleep-number frame that adjusts? Don't see why not. It's pretty flexible. But on top of other mattresses - excessive - it's 8in tall!

      • It is pretty flexible and should work on a sleep number frame.

      Read more Read less
    • is the cover removable?

      • You can use an additional mattress pad or sheet if desired; this will not affect the performance of the foam and will protect the original cover from being soiled. Please make sure the additional cover or pad is a breathable material. We recommend this because taking off the cover of the mattress or washing the cover will void the warranty

      • The cover is removable, but difficult to put back on. I did it as a one man job when I moved to a different city. I had to wash it, but it was really difficult to get on. Not impossible, but difficult.

    • Are there any issues with the memory foam getting dips, on it where you lay? (I had this issues with an off brand one before.)

      • You shouldn't have any issues with this, it is a very good product and it has 5 stars.

    • What is the warranty on this mattress?

      • There is no Manufacture Warranty. However, you can purchase the 10 year Extended Warranty for $49.99.

    • Does this Bed support a very large person (350#)?

      • Yes, but we do not recommend putting more than 275 pounds on either side of the mattress.

    • Is this a firm or medium firm foam mattress?

    • What is the warranty on this product?

      • I can only tell you that I bought one of these a few years ago. The warranty promised everything but after 6 months the bed developed divots you could get lost in. All my requests for replacement were returned with copies of the warranty which said things like "discomfort is not a reason for return," and "some settling is to be expected." Basically they leave themselves every possible out. Don't buy it unless you can get a copy. It may have changed but I found it totally frustration. I threw it out.

    • I want to go from Queen size to King, but I am concerned about getting a King into bedroom. What is the pre-inflation size of this matress?

    • Can this mattress be used directly on floor without any bed, for sometime?

      • For best sleeping comfort, we would suggest using a box-frame, or platform bed.

    • Can this mattress be used directly on floor without any bed for sometime?

      • It is not recommended that you use this item on the floor as it is meant for use with a boxspring or platform bed. However, it can be used on the floor if needed.

    • can this be used on a platform bed or do i need a boxspring?

      • This mattress can be used on a platform bed that has enough slats to support it.
