Memory Foam Do's and Don'ts:
  1. To maximize memory foam expansion; remove from packaging within 72 hours of receipt.
  2. This product arrives very tightly packed. Please unwrap and allow 48 hours for this product to return to its original shape.
  3. Being sealed in plastic packaging sometimes traps odors. A few hours of airing usually removes the odor.
  4. Due to machine cutting manufacturing processes, 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

  • Good for the first 6 months...

    This topper is great for a short term fix. It worked great for the first 6 months but fell short thereafter. Purchased it to replace the pillow top on our air mattress (air mattress was 12 years old). I ripped the old pillow top off of the air mattress and placed this pillow top directly on top of the air mattress. What a charm at first but then after approximately six months I starting to feel a depression on my side our of king size bed (the "w" syndrome) again and was awakened with hip and back pains. I purchased this topper back in June 2008 and wanted to wait a fair amount of time to provide a meaningful review (kick the tires so to speak) as most reviews provided on this site are provided within the first 1-2 months of purchase. Feel the price paid for the topper was fair given the short term fix it provided. I now know its time to replace the existing topper or consider purchasing a new bed (perhaps the latex toppers would last longer??). As for how hot or cold the topper makes you feel toasty warm in the winter and comfortable in summer (with central a/c). I am 5'3" weighing in @ 130lb and sleep predominately on my side and stomach. Hope you find this review helpful.

  • Not the best memory foam ...

    This is not the best memory foam we've owned to date. It doesn't seem to have the same support and comfort levels of previous (non-blue) mattress toppers. In addition, it has a "chemical" odor that seems to really bother my wife, even with a mattress pad and sheets over the pad. Not bad for the price, and still better than the mattress itself ... but, I wouldn't purchase this item again ... I'd go back to the traditional memory foam.

  • memory foam mattress topper

    this mattress topper is very comfortable to lay on,however the reason I purchased it from Overstock.com is,the way it was advertised on their website as being very different from the other "memory foam "mattresses on the market,in that,it was "not "supposed to heat up from your bodyheat overnite as brands like Tempur-Pedic has been known to do.But,it does!! it was supposed to sleep Cool because of its' different type of foam.But its'the same as 3 other brands of memory foam mattresses I've tried .I still wake up some mornings hot & sometimes sweaty and it's still winter,it's going to be more difficult when Spring & Summer arrive!


    As an ex-gymnast, I have more joint and back problems than I can list and woke up with tears most mornings from pain. This topper made sleeping enjoyable again and virtually pain free!! The only negative, you will hate when you have to sleep in a bed without it and will wish it was portable. The only thing I will say is the color is a bit ugly and can discolor but who cares when it is topped with sheets. Just make sure to let it unroll and sit out for a few days to air before putting on your bed.

  • 3-inch "Cool" Memory Foam Mattress Topper

    Nice concept, but this foam is not comfortable to me. It is much too firm and did not do away with the "hot spots" that were causing joint pain. Also, the material is very fragile. It tore while unrolling the packing. Overall - it's only "OK" at a premium price. The cheaper foam toppers are better.

  • So comfortable!

    Would recommend this to anyone for comfort. This has been the best thing for my back pain. It does sleep hot. But it's a trade off I will live with, considering my back hasn't gone out on me once since I bought this.

  • Mattress topper

    Pros: Exactly as described; seems to be high quality foam; softened the very firm mattress just right. Cons: Easily 10 days of off-gassing (I should have waited until 2 weeks went by before putting it on the bed); comes JUST as a sheet of foam; no coverlet of any kind.

  • mattress topper

    we are happy with this mattress topper. It is comfortable to sleep on

  • Great quality!

    This was worth the investment.

I did a lot of searching on your site and shortlisted two memory foams: Slumber Solutions Gel Memory foam 3 inch mattress topper and Comfort dreams Mem-Cool 3 inch memory foam topper. When I read the product specifications, i found Comfort dreams to be better (as it had temperature adjustment, allergy prevention features etc), but when i read the product reviews, i found them to be totally opposite (most reviews say that it does not last for long and heats up!). I need a high quality brand for a +70 year old patient. We were already using a topper (do not know its brand name) that lasted for many years. Please guide on best available option? basim on May 30, 2014

I can't answer for the Comfort, but I have purchased and love the Gel Memory Foam topper. I have severe spine issues (4 surgeries,etc.) and heat up quickly! I have used this topper for over a year now and love it! It is still keeping it's form/fluff and still keeping me cool..and not cold! My husband has fallen in love with it too! As he was very skeptical...also...he is not a little man..(200+ lbs..) and the foam still plumps up, night after night.... kiimgg on Jun 10, 2014

With information provided and simple math, I calculate the density to 2.38 lb. to 2.48 lb per cubic feet for the various sizes. That does not match the description on 4.0 lb? jemindal on Feb 1, 2014

we own the 3" memory cool topper for two of our beds. I would call them a medium firm but not a firm. muffinhowland on Mar 21, 2013

Subscribe to Answers
Answer This Question

A general answer to this question is that many manufacturers make product for companies that private label them. These products you are speaking of may not have been labeled. overstockcustomercare1 on Jan 10, 2013
I wouldn't call this a generic form of the product just because it does not have a label. It is packaged with information on it and is exactly as you see it on Overstock. We own two of these for king sized beds and have had them for quite some time now. They are still in like new condition and hold up very nicely. The description provided by Overstock is right on the mark for this product. I for one appreciate the excellent prices that Overstock offers on quality goods like this. Have you priced this on other sites? I think you would be surprised at how reasonable Overstock is. muffinhowland on Mar 21, 2013
