    • Firm: 1-inch layer of 4 pound memory foam, 2-inch layer of 2.5 pound memory foam and 7-inch layer of 1.65 pound conventional foam base
    • Originally designed for NASA, this space age foam cradles the body, reducing pressure points that cause tossing and turning

      Verified Purchase

      Really wish I had gotten the soft version. I ordered the Medium because my husband really wanted something a bit firmer that you don't sink in but this is to hard causing both of us stiff necks and back pain. What a mistake! I had the same mattress in Soft in Queen size, but we needed a bigger bed and thought that since I loved the Queen version we would love the king just as much. Regret my purchase!!! Will be looking for another bed. $*wasted!

    • Wonderfully comfortable mattress is my favorite ev
      Verified Purchase

      This is the 2nd of these mattresses I have bought. I have had the first one for 5 years and it is still in perfect condition. It is the most comfortable mattress I have ever slept on. I have the firm and I highly recommend it. Guests also remark on how comfortable it is quite frequently. I think this is a great buy on all levels.

    • Great product for the price
      Verified Purchase

      I have bought this mattress in various sizes for five different bedrooms over the past few years. We have this King and two full sized in our beach rental and renters leave comments on how comfortable the beds are. That's a true review. I believe we bought the softest level, because I read how firm the others are but I don't think you can go wrong with any of them.

    • Too Good To Be True
      Verified Purchase

      Well, we took the plunge after reading how happy everyone else was with this mattress. And here we are, not even a full six months later, in the market for yet another new bed. We had such high hopes! And it was heavenly at first, this bed. Like a cloud! But my husband, all 6' 4" and 275 lbs of him, crushed down the foam on his side in less than three months. So we spun it around and the 120 lbs me slept in the sunken spot, as we figured I was lighter and therefore wouldn't sink as much. Now, there is a sunken spot on both sides and the once beloved mattress is headed for the trash. If it had just been the 120 lbs me, the bed probably would have lasted forever. But if you weigh in excess of 200 lbs, DO NOT BUY THIS MATTRESS! Unless, that is, you only need to use it for three months... And I must say, in all fairness, that the first three months, before the crushed down foam lost its memory, that was the best bed I ever slept in...... The BEST! Alas, ours was but a brief encounter, and doomed from the start it seems... Still, before it got all forgetful, I loved that bed passionately...

    • Select-A-Firmness Worth the Extra Money
      Verified Purchase

      Prior to this purchase, I had purchased an OVERSTOCK bulk pack of two 10" Queen sized mattresses for the guest rooms in our new weekend home. We also needed a bed for ourselves so we decided to try these before we purchased a King sized. We liked it! The MEMORY FOAM is very different from what we are used to (a number bed) - much harder but, still very comfortable. And it was not at all hot - a real concern for this 50+ woman. LOL. After the first weekend, we were hooked. I came back to OVERSTOCK to search for the King and found this SELECT-A-FIRMNESS. I ordered the MEDIUM and I have to say that it is worth the extra money - (about $70.00 if you are an Club O member.) There IS A NOTICEABLE difference in the firmness and both of us are glad I paid for the option. It was packed "tootsie roll style" - like the queens but, in a plastic sock instead of the canvas. It plumped up quickly- we slept on it the first night and, we didn't notice any smell at all, (and I know the smell others write about because I've ordered memory foam pads - they smelled for weeks - and were hot.) I recommend HIGHLY this mattress. (And my friend who purchased the name brand thinks that this one is just as comfortable as hers.) If you are at all concerned about the firmness, try the SOFT but, keep in mind that the closer the mattress molds to your body - the warmer the mattress will feel. Thank you OVERSTOCK. This mattress is a great value!

    • Does Not Stand the Test of Time
      Verified Purchase

      I tried the Comfort Dreams mattress in hopes of bypassing the higher cost of a Tempurpedic model. At first the mattress worked well. It did not have the same quality of overall comfort the Tempurpedic models had, but for a fraction of the price I was OK with that. Many of the reviews I read were very similar. The problem showed up a few months into ownership. I did not realize how many of the reviews were written in the first few weeks of receiving the mattress. The foam does not hold up very long without starting to collapse, or cave in, or whatever else you wish to call it. I tried turning it around (head to foot) which did not work either. Just for the record, the mattress never got wet or had any issues with being mistreated. Luckily I found a great deal on a nearly new Tempurpedic; I purchased it and have had none of the issues listed above. The Comfort Dreams mattress is now in our guest bedroom because we cannot sleep on it with any comfort.

    • had 3 years it needs relpaced

      We purchased this mattress 3 years ago. Both my husband and I are average weight. our mattress now sag's where we slept during the night and we both wake up with neck and back problems. It has no longevity. I would not recommend wasting your money on this mattress un less you want to replace it in a few years.

    • Great Buy
      Verified Purchase

      I'm actually in the mattress industry. Definately needed a memory foam mattress. At this price, for a king size, it was a no brainer. Down side is, ther's no warranty, but for $****, i'm fine with it. I weigh about 225 so I opted for the soft. I actually find it comparable to the Tempur-Pedic cloud but thicker. The smell isn't a plus either but i know it goes away after a couple of days. Great feel. Great price! if you're heavier than 260, get a medium, more than 300 get the firm. Looking forward to buying more of these for my family if need be. Memory foam isn't for everyone but if you need better pressure relief, this is the way to go. Just remember this, the bed should conform to you. Not the other way around

    • I bought this 3 years ago and the extended warranty but it's not showing in my purchase history. I am guessing because of that I am stuck dealing with the stock 5 year warranty? Can you provide the link for it?

      • Please contact Customer Care at this link

    • How much does this mattress weigh? Also what is the shipping size?

      • Hello cookin4life, the package dimensions are approximately 81 inches x 16 inches x 15 inches and weighs approximately 91 pounds. Thank you for shopping with us.

    • Why did you choose this product?

      • Reviews

      • I purchase three of these. This will be our fourth mattress of the same brand. I like the "firm" option. Our guests say this is the best mattress they have ever slept on.

      • Referral from a friend!

      • highly recommended by a friend with one

      • If I like it and the quality is great, I'll buy another one. The 10 year guarantee is a joke upon most mattresses and you will never get your money back.

      • Referred by daughter

      • We already have one of these (medium) for 7 years and love it.

      • Previous purchase.

      • Have queen size already and needed more space

      • i have another one of these and absolutely love it! needed a new king mattress for an extra guest room1

      • previously slept on a similar Queen size that provided my husband and I great nights of sleep. very hopeful that this will as well.

      • I have the same mattress in a queen size and really like it.

      • Very comfortable mattress. This is our third one.

      • Third time owning this bed (we've moved for work the previous two times and had to sell it prematurely). Amazing and consistent.

      • A friend referred me to it.

      • bought this Queen size last 4 years ago.

    • I see the mattress comes with a 5 year warranty. What is not covered?

      • Hi jenimari, after reviewing with our support staff we found that the 5 year warranty does not cover normal wear which includes the additional increase of foam softness or a decrease of the foam recovery. The warranty does cover deteriorating foam with a visible indentation of one and one-half(1.5) inch. The warranty will not cover mattresses that are used on inappropriate foundations, box springs, or adjustable beds that are creating a sag in the surface. All warranties will not apply if the mattress, foundation, or cover has been physically abused, damaged, burned, stained, cut, or torn. I hope this helps, thanks for shopping with us.

    • Do you have information from the manufacturer on the chemical content of this mattress? I just bought one and it seems fine (odorless) but I have been reading up on chemicals in foam mattresses and have some concerns.

      • Hello swimmy44 The manufacture states that they do not release the specific info about the make up of our foam,but they pass all of the Cal 117 and US Laws regarding manufacturing of foam. I hope you find this information helpful.

    • can this matress be cut to fit an odd size platform? does the cover come off, so I can cut like 4 inches off the width? then replace the cover? Knowing of course the cover will be a bit sloppy

      • Hello jeddar, We don't recommend cutting the mattress, it would void the warranty. Thank you for shopping with us.

      • I would say don't do this - my platform is odd size and my old mattress overlapped about an inch on each side and it was just fine. These foam mattresses are not easy to cut without the proper equipment unless you are talking a very thin foam like 4 inches. Plus if there is a mattress cover already sewn on it would be a very big production.

    • Does this mattress contain latex?

      • Hello vluna10, This mattress looks so comfortable! This mattress does not contain any latex. I hope this helps. Thanks for shopping with us.

    • Which mattress is firmer: 11" select a firmness in firm or Coolmax 10"

      • Hello laurie4861, 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. Please feel free to contact us again with any further questions. Thank you for shopping with us!

      • I just bought the 11" Comfort Dream and it is very firm but not board hard - which is what I wanted. The foam top sinks in a bit, much less than my 8-10 year old one which was just described as "memory foam" no specific firmness.

      • I bought the 10" size and it was comfortable, but I also got a fluffy mattress cover. I sleep great.

    • Is the king firm safe for babies to sleep on?

      • Thank you for your interest in the Comfort Dreams Select-A-Firmness 11-inch King-size Memory Foam Mattress. This should be safe for a baby to sleep on.

    • For a king firm - How many pounds per cubic foot?

      • Hello jle127! The firm has the following: 2-inch layer of 4-pound memory foam, 2-inch layer of 3.0-pound memory foam, 7-inch layer of 1.5-pound urethane foam. Thanks for shopping with us.

      • I don't know, but it's heavy! Good mattress, but our UPS delivery man hates us!

    • Can the mattress be put on a bed with 12 slats support directly?

    • Is there a warranty against sagging? For instance with some other memory foam mattresses if it dips more than 3/4 inch there is a warranty against that.

    • How do you wash the protective cover of the mattress or can you even wash it?

    • what size and weight of the mattress in the plastic box. How long can this mattress is stored in the plastic box

      • We don’t recommend to have the mattress stored more that 2 months. The size of the mattress is 76 x 80 and the weight is 91 lbs. The package dimensions are 81 x 16 x 15.
