  • 11-inch memory foam mattress with coolmax cover
    Verified Purchase

    We've slept on this mattress for a month now - on the first night we got the best sleep we've had in a long time. It is a very comfortable mattress. Neither my husband or I have the aches and pains we used to get from sleeping on our Sealy memory foam mattress (which was less than a year old). I hope this one lasts a long time -

  • Good buy but rather FIRM
    Verified Purchase

    For the money this is a great product. It is our first memory foam bed and it is nice because i don't bother my husband when I toss and turn at night. This mattress does come with a mattress cover free(I recieved several days later). It is very firm and takes some getting used to, but I feel rested after sleeping on it. There is no smell problem as some people say with the foam. I let it stretch out for several days before I slept on it and I am fairly happy with it. If u like the plush sinky kinda mattress, this is not for you! It also shipped sooner than expected so don't let the ship time scare u off! zzzZZZzzzZZ

  • the price is right
    Verified Purchase

    needed to replace old mattress and wanted to try a memory foam but didn't want to spend a fortune. This mattress is excellent for the price. My husband and I both are sleeping better and do not wake if the other has to get up in the night. For me the mattress is a little warm (I'm mid 50's so probably anything would be warm). The husband has not complained a bit about it being hot. It has not taken away the little aches and pains as some are advertised but they haven't gotten any worse either. We are very pleased with this mattress and I have already recommended to friends.

    Well after sleeping on a soft side water bed that I must say I truely loved and did not want another bed. This bed is very nice it did take me about a week and a half to get use to it now I sleep like a baby! I recommend taking the warrantee its worth the peace of mind and they send you a water proof cover. Love it Love it!!

  • great buy
    Verified Purchase

    couldn't be happier with this purchase. extremely comfortable, and just the right amount of firmness vs. comfort. was skeptical about buying a mattress on-line, but am really pleased. i'm a good sized guy, and it provides great support/comfort.

  • Amazing...what a value
    Verified Purchase

    I was skeptical purchasing this on-line without trying it out first. I saw this same mattress at a wholesale club for $1100 and then decided to give it a try. The mattress is life changing! It is not a "fall into a cloud of memory foam" mattress. This mattress stays very cool (a big problem with most foam). My old (much more expensive) mattress used to make my arms fall asleep and my lower back hurt...I thought that I was just getting old! My back pain is gone and I sleep soundly. The mattress was shipped promptly and the quality of finish and construction is top notch. Buy with confidence!

    We like a firm mattress, and, after reading the reviews on all of Overstock's king memory foam mattresses, we chose this one. Before ordering, I called Overstock's customer service to find out more information on the memory foam. Customer Service informed me that both the inner & outer foam was a 5lb foam. We have slept on the mattress for about 2-1/2 months & really like this mattress (we previously had a Stearns & Foster firm mattress, which we liked a lot - but it failed after 5 yrs). It is a good looking mattress - you wouldn't know that it is memory foam. The Cool Max cover is nice & helps make the mattress look more mattress-y. We still use a mattress pad cover on the mattress so we don't have to take the Cool Max cover off as often for washing. The mattress is firm, but not rock hard. If you normally like a firm mattress, this one will be a good choice for you.

  • Dreamy...
    Verified Purchase

    I've had this mattress for a little over a month and I don't know why I waited so long to buy a foam mattress! After shopping locally and getting a good idea about what I wanted, I began my internet search and found this one. I saved several hundred dollars over the local dealers and it was delivered right to my door for FREE! I love the coolmax cover, it makes it almost feel like a pillow top and it cuts down on the body heat retention problem. I would deffinately recommend this product!

    Verified Purchase

    Lead by the good reviews and after re-searching for months i decided to order. Heaving constantly back problems, I was hoping that would resolve my problems. The opposite happened, my back seem to hurt more. Pros: no smell Cons.: not firm at all as expected, cool pad seems not to work, still sweating
