    • Great Bed

      I received this bed yesterday and so far, it's great. It's definitely on the firm side but I usually don't like firm mattress and I found it very comfortable. The price is unbeatable and overstock customer service was really helpful. I debated returning the bed for a queen when the bed had already shipped and overstock offered a one-time free return. It would have cost hundreds to pay for returning the mattress so I was very impressed. The bed comes rolled up in a long piece of cardboard, and mine inflated immediately upon opening with no smell. Overall, I'd definitely recommend this mattress. I'm planning on using it with a platform bed without a boxspring.

    • Wow!

      This is a fantastic memory foam mattress! We couldn't be more pleased. We needed it for a 6 month vacation rental so we didn't want to spend too much. This is a great buy on a crazy comfortable mattress. I will lug this home to keep because we like it so well. Much more comfortable than the $2000 mattress we have at home! It is firm, but very comfortable!

    • Very comfortable

      We bought this for the bed on our boat. I intended to trim it to fit the rounded ends of the frame perfectly, but decided it wasn't worth the bother. This makes sleeping on our boat 100 percent more comfortable. We bought a second mattress for the forward cabin and got an upholsterer to cut and cover it to fit the beds in there. We had a friend and his son sleep there and they said it was much better than their beds at home.

    • Horrible!!

      If your looking for a mattress that will last do NOT buy this one. My boyfriend and I have had it for over 2 years and its has caved in on each side where we sleep, we are not big people. I have never had back problems and I wake up each morning in pain and dont feel rested. We cant take it anymore and are buying a new mattress.

    • Great Vaule!

      We had purchase the mattress to replace our current air mattress system. We highly advise "against" the use of an air mattress system. Never again. We did not want to use innerspring or waterbed options. We have looked into memory foam mattresses in stores but was taken aback by the $3000 price tag. Hard to look away from the values offered at Overstock. So we decided to try out the Overstock option. We were a bit concerned about a mail order/ sight unseen purchase. We are very happy with our purchase and we are sleeping very well on this new mattress. My wife and I both noticed we no longer get out of bed and hobble like we are crippled when we started to walk. My concern was that I would to too hot on it. That has not been an issue. We do use a pillow-top mattress cover so that may be a factor in comfort. Also it is very cozy on the winter nights. Somehow the memory foam keeps you body temps very well. Neither hot or cold. I have already highly recommended your product to my friends and have told them of our complete confidence in buying from Overstock. We most definitely will be making future purchases again through them. Thank you for a great product and great service. The shipping was quick. Very satisfying consumer experience!!!

    • Awesome Mattress!

      We are completely satisfied with our purchase. It's a little scary buying something sight unseen that you spend so much time on but after reading all the great reviews we felt it was worth the risk. We have not been disappointed. The mattress came in a timely manner and was easy to unpack and get in place. It didn't take too long to expand to it's full size and is super comfortable to sleep on. We bought an inexpensive regular king size mattress and put this on top so with the two of them it measures about 15-16" which is perfect for buying sheets. We feel like we have a luxury bed for a whole lot less!! Buy and enjoy.

    • Fantastic

      Had no idea how I was going to get king size mattress to third floor loft. I read all of the reviews & decided to try this. It comes rolled up like carpet, open & within hours is full size & so comfortable. Worked fantastic for me on a platform bed. Great value!!

    • 8" Memory Foam Mattress

      Love it! UPS delivered within a week, (we live in the boondocks) we opened it and allowed it to 'breathe'. It didn't smell bad, but I like to ' follow the directions '. Placed it on bed frame, placed previously purchased from Overstock 4 " topper on top of it and have been happily sleeping on it ever since. VERY NICE cover encloses the foam mattress. Would buy again! :)

    • I am very happy with this purchase

      The delivery time was much faster than I expected, the mattress took mere minutes to plump back to it's original shape with little detectable odor. My one complaint is that is it so comfortable I never want to get up! And all for under $*** - sweet!
