  • Good matress, but a couple things not as expected

    Overall, this is a great memory foam mattress for the money: Pros - High quality, resilient memory foam - Cool top layer really does help it from overheating like traditional memory foam - Great price on Overstock, at least half off retail prices for similar quality - Shipping was fast and easy Cons - Not actually 15 inches thick after shipping. Even after unpackaging the mattress and leaving it out for 48 hours before using it (as many memory foam products recommend), the mattress only expanded to just under 14 inches thick. I even waited an extra day (72 hours total) before using to see if that would make a difference. It didn't. However, only about 1 inch of difference in thickness isn't a big deal to me, so I decided to keep it. The other dimensions were accurate. - Slightly less firm than I expected. Admittedly, it's hard to gauge firmness without trying firsthand because the scale isn't standardized across manufacturers. However, the description noted that the mattress is made of layers of both 5lbs/cubic ft and 4lbs/cubic ft foam. This is considered very high density by most. I expected this would also give an extra firm feel. Instead, I would say the mattress is firm to medium-firm. Nonetheless, the memory foam seems of high quality and is very resilient. Overall, I am happy with the purchase and think it was good deal. The mattress is much better than most "bargain" memory foams I've tried out in person and nearly as good as the top of the line brands. Definitely worth the money, but note the thickness when buying sheets and keep in mind it may feel softer than a traditional mattress.

    • How did the color on site compare with the actual product? The color was accurate (but unimportant as it's covered by a sheet).
    • Please tell us about the quality of the product. The quality seems high, certainly for the price.
    • How accurate was the on site description of the product? There were a couple inaccuracies
  • Best purchase I have ever made online!!!

    I have never made a purchase from overstock before let alone such a large one online. Buying a mattress from overstock was easy, fast, and reliable. This mattress has almost reduced my morning back pain by 100%. there was no weird smell when I opened it. the matress stays cool at night and is soft but has the perfect amount of support. I was also able to purchase ans extended warnty through overstock. the papers were sent a week after I recieved my mattress. friends have told me it feels like a 1400 dollar mattress ( but i didnt even pay half that!!!) WORTH EVERY PENNY!!!

    • How did the color on site compare with the actual product? same
    • Please tell us about the quality of the product. excellent
    • How accurate was the on site description of the product? 100%
  • Sleep Like a Baby

    I have been wanting a new mattress for a long time and did quite a bit of research. My previous mattress was a pillow top and did not hold up well. This mattress has exceeded all of my expectations. Soft but supportive and comfortable. I actually enjoy going to bed now and wake up without the back aches and head aches that i had with my old mattress. I just love it!

    • How did the color on site compare with the actual product? Exact match
    • Please tell us about the quality of the product. Exceptional
    • How accurate was the on site description of the product? Very accurate.
  • exceeded my expectations!

    let me start by saying that I am by no means a memory foam aficionado. Prior to owning this mattress I had slept on one other memory foam mattress a handful of times - I loved it (hence my purchase) but found it to be very hot once I woke up. With this mattress I don't have that problem! I'm enjoying the best sleep I've had in years and waking up totally refreshed ( and not sweaty!) I've had this mattress over a month, and haven't noticed it losing elasticity yet. Being a large girl too, I've found it's incredibly supportive. All in all, I'm sure better products exist - but this is a great buy!

    • How did the color on site compare with the actual product? perfect match
    • Please tell us about the quality of the product. high quality
    • How accurate was the on site description of the product? very accurate
  • LOVE this mattress!

    This bed is like sleeping on a cloud. I needed a bed that did not compress nerves or other pressure points and provided great support. I'm both a back and a side sleeper. This bed is the most amazing's like being cushioned in a cloud. It keeps me from sweating at night. It is wonderful. I bought a 3" gel foam topper for it, as well, as I wasn't certain how firm it might be. It is truly med/firm. The 3" topper was a great addition (i was worried my sheets wouldn't fit over both, but they better than ever) took the bed from awesome to REALLY AWESOME. Also, for anyone concerned their bed will smell funny when first doesn't I let it breath for one day and by nightfall she was ready to go. No strange smells, super comfy. LOVE IT.

    • How did the color on site compare with the actual product? just dandy
    • Please tell us about the quality of the product. wow...amazing
    • How accurate was the on site description of the product? didn't even give it justice

    This bed is the most comfortable bed I have ever slept in. No odor (as reported by others) upon opening package and bed was in perfect condition. It was ready to sleep on in less than 48 houses. Great purchase.

  • Piece of junk

    I'll preface this review by saying that I've NEVER had a problem in particular with a bed. I also have to give you insight that my husband and I are healthy, fit, lean athletes who take care of their bodies. Those two things being said, this bed is positively HORRIBLE!!! We've given it time (purchased in September 2015) to try to 'get used' to it, and we've had only PROBLEMS ensue!! I researched like crazy in trying to make the best choice, and this seemed like it. I wanted a firm, QUALITY memory foam bed that did not break the bank. Well, where this one was significantly cheaper than what you will get in a mattress store, it is also JUNK!! It is NOT firm---the foam is extremely mushy and NON-SUPPORTIVE!!! It has already sunken deeply in the spots where we sleep!!! I own a pillow by the best memory foam bed maker out there (whose name begins with a T), and I can promise you that the material of my pillow is ENTIRELY different than the swill they used to make this bed! I have also slept on beds by the same brand (that begins with a T), and they ARE AWESOME!! This bed is SOOOOO entirely NOT quality memory foam!!! I have appendages that go numb due to the total lack of support of this bed!!! All I can do is warn you against purchasing this. I can promise you that we will be looking into buying the REAL thing (by the brand that starts with a *), because quality of sleep is important to your health! This thing needs to go into the dumpster....

Our product details list this as a firm mattress. overstockcustomercare1 on Feb 24, 2012
It's difficult to explain, but the mattress gives on the top (several inches) but is firm and supportive under that. You won't sink too low but it gives just enough for the natural curves of the body. I have lower back issues and this is the best thing for it. ryetyme on Oct 30, 2012
