    The bigger the bed, the better the sleep, right? Right.  Let this California King bring you on a direct trip to dreamland. Naturally antimicrobial, this mattress resists dust mites to provide a healthy spot to sleep. The memory foam mattress stops motion transfer so you won't wake up at night every time your partner moves, ensuring restful sleep.

    • Mattress is available in three firmness levels: soft, medium and firm
    • Eliminates motion transfer and uncomfortable pressure points common in most innerspring mattresses
    • Originally designed for NASA, this space age foam cradles the body, reducing pressure points that cause tossing and turning 
    • Can be used with existing box springs or platform bed
    • Base layer is conventional foam with a 2.5 pound foam layer for comfort. Resistant to dust mites and is naturally antimicrobial
    • Mattress measures 11 inches high x 72 inches wide x 84 inches long
         Memory Foam Tips:
    • Remove from packaging within 72 hours of receipt to maximize expansion.
    • Product arrives very tightly packed. Unwrap and allow 48 hours to return to its original shape.
    • Being sealed in plastic packaging sometimes traps odors. After unwrapping, allow product to air for a few hours.
    • 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.

    • Great bed for value
      Verified Purchase

      The medium mattress is pretty firm, with little give BUT this is exactly what my husband was looking for. The mattress doesn’t sleep hot and has a nice height to it.

    • Nice, but firm for a "soft" mattress
      Verified Purchase

      I personally do not like this mattress because it is so firm despite ordering the softest version. We placed a pillow top cover over it, but I still feel like I'm sleeping on a board. However, my husband loves the firm feel of this bed. Either he no longer tosses and turns, or I simply don't feel it because the bed has no bounce to it. If you prefer a firmer feel to your bed, then this might be the mattress to bring you sweet dreams.

      My husband swears he sleeps better, deeper and longer with this mattress! I think it is 100% better that that old pillow-top we were using. We got the medium firmness (even though my hubby wanted the firm) since I am hoping that as it "softens" over time the medium will go to soft and still be comfortable. BTW...have had this mattress about a year now with no evidence of any loss of firmness.

    • Unexpected, but great mattress
      Verified Purchase

      When the delivery guy came with this mattress, he thought it was a rug because of the way it was packaged--all rolled up tightly. It expanded to about 10 inches immediately after cutting through the tape. It also has an unexpected bamboo (anti-microbial) covering. First night was a little different from our spring coil, but since then, it has been great. I rarely wake up, or move, for that matter! It is firmer than I expected--I ordered a medium--I wish I ordered soft, but I was worried about it being too soft. I thought about ordering a mattress topper since this was so cheap, but the firmness really hasn't been an issue since I've been sleeping all night--same with husband who is 6'4" and 230 lb.:) Great buy!

    • Welcome back pain-free mornings!
      Verified Purchase

      The last bed we had only had a 2 inch memory foam topper on it which was great in its own. I decided to upgrade to this memory foam mattress and I'm so glad I did! The first couple of nights my husband and I slept on it, i was woken up numerous times with hugs and kisses and his voice thanking me for purchasing such an awesome mattress. And it looks as great as it feels. The cat, who usually jumps out of bed after lying in it for about ten minutes, spent about two hours 'sawing logs' in a deep sleep on this mattress. I would recommend (and have recommended it) to everyone... cats included.

    • Awesome Product! Comfort Dreams is really AMAZING!
      Verified Purchase

      I was contemplating getting the Contour Signature Memory Foam by TempurPedic, yet it was really expensive. I went to Overstock to see what they had in terms of memory foam beds. I saw that this mattress had great reviews and thought I would give it a try. I went online and found a coupon for 10% off the Overstock website and got this mattress for much less including shipping for a Cal-King firm mattress. I unwrapped it when it arrived and it did not really smell like everyone said. I set it outside for about 6 hours and then set it up. It was immediately impressed. This bed is really comfortable and the firm is perfect for my husband and myself. We are runners and in our 40's so having a firm mattress is really important to support our back and core. We slept like babies! This mattress is very comparable to the TempurPedic signature or TempurPedic Contour Select for so much less. I highly recommend this mattress!

    • 11 in Select-A-Firmness Mem Foam Cal Kng Mattress
      Verified Purchase

      I have found the above mattress to be a good product. I was a little apprehensive at first because coming from a worn out spring mattress to this was an adjustment for me and I did not get the type of sound sleep I expected. But after about 3-4 days, I had some of the best sleeps of my life since I stopped using my tubular waterbed 3 years ago. I think it takes a few days for your body and the foam to get acclimated to each after which the memory form gets accoustomed to your body weight. By that I mean it gets compressed in the same way and accomodates your weight and form. I bought the firm mattress because I like that type of matress and I'm a big guy (6ft 250 lbs). Also because mattress that is too soft gives me back pains. In the first 3-4 nights I did not get the total restfull sleep I'd anticipated but every night since then it has been sleeping bliss. I'd recommend this product to anyone whose in the same category as I described above. On a final note I was a bit disappointed by the Cal King Memory Foam Pillows that I also purchased. I had been shopping for this product for over 6 months during which I'd seen, tried out, and evaluated the designs of both the mattress and pillow. The other pillows I had seen/tried were either made of a composite of memory foam and some other denser foam in the core or had a sculptured shape that had a thickere portion at the widest side os the pillow to support your neck. These pillows were just a piece of memory foam cut into the shape of a standard shaped pillow (with the proper length for a king bed) that is thickest in the middle and tapers to a slimmer thickness at the edges. It wasn't very thick in the middle so when any weight was put on it, it compressed to thin profile that barely supported your head with any elevation. Though it sort of works for me since I prefer a flatter pillow, but I believe it might be an issue for other people as its barley supporting my head in the fashion I would have suspected, based on the other pillows I tried. Of course once you open the package you cannot return the item, so I'm stuck with it, but I would have wanted to exchange it for a different type of pillow if I knew ahead of time that was the type I'd get. So I'll just have to chalk it up to dealing with the prevailing policies when you purchase through the internet.
