    • Sleeping never felt to good

      After months of searching for a memory foam bed, I noticed they all had 1" to 2.5"s of memory foam on top of regular foam. That was a bummer. Then I came across this 4" topper. I purchased a 6" spring mattress, which was great and then added this topper. I did the best thing possible for my body. It's Nirvana. My mother took a luxury cruise and said the beds were the same as this one. not to firm but not to soft. (I prefer firm). So, if you want to sleep without reading before bed, as I used to do, get this topper, you will love it. Better yet, treat yourself to it, you deserve it!

    • Not as firm as I thought

      I did lots of research and unfortunately this mattress isn't firm. Which is what I wanted. But it does mold to your body. So I'm not sure if I misread the description.

    • Not Cool or Firm

      This is my third topper - bought it to replace a 3 inch older topper thinking a newer thicker topper would be more firm and since its 'Mem-Cool' thought it would be cooler --- and its neither. Not Cool- hotter than my previous. Not firm at all. Very disappointed. .

    • mem-cool exceeds claims.

      I have 4 inch memory foam on every bed in my home and I have recommended to all my friends. However,although memory foam gives you a better sleep it can tend to make you warm even with a bed pad on top. Since I like to sleep in a cool environment I decided to try the Mem- Cool. What a difference! This product lives up to all it's claims. Although it cost a little more it is well worth the price . After I opened the package it only took 12 hours for the slight odor to dissipate .From now on I will only recommend 4 inch Mem-Cool Memory Foam Mattress Topper.

    • Dreaming in Comfort

      For years I had been anticipating getting a tempurpedic mattress and sleeping within blissful comfort. After getting one I was so very disappointed. I would wake up with my entire backside slightly damp from sweating. It also truly was not very comfortable. I ended up sending it back within the 90 day guarantee. My husband and I then ordered a sleep number bed and it is ok but not wonderful. I hemmed and hawed about ordering this mattress topper for about a year and am so extremely glad that I did. It is amazingly comfortable and does not make me sweat. This addition to our bed is nearly as comfortable to sleep on as the best mattress I have ever owned. I am thrilled with my purchase of this product!

    • Finally Free of Back Pain

      I have been suffering from severe lower back pain almost from the minute I lay down at night on my 22 year old pillow top EXPENSIVE mattress. I would wake and get up several times each night or just toss and turn and rearrange pillows every night. I even placed soft pillows below my lower spine with no help. This has gone on for nearly 2 years now. I was even going to have a doctor check me out for the beginnings of problems with my sciatic area. I finally invested in this memory foam mattress topper because of the "Cool Max" feature. From the very first night I used this, the pain in my lower back and hip completely stopped. I have slept comfortably all through the night (except if the cats jump on ME) I don't even feel them jumping up on the bed anymore! I look forward to many more restful nights of sleep in the future. There was NO smell when I unwrapped it. The box with the king size sleeper WAS heavy..... about 50 pounds. So it was a bit of a struggle to do this myself but once on the bed and unwrapped, I was able to put a deep pocket fitted sheet over it immediately and make up the bed. There really was no waitinig time for a smell to subside or for the mattress to full lay flat. All in all, lifitng it up two flights of steps and getting it on the bed and the bed made up took me about half an hour. THANK YOU THANK YOU THANK YOU for offering this wonderful product.

    • Unbelievable Sleep

      I LOVE this product! It's made sleeping so wonderful that I never want to get out of bed. I actually think about it when I'm out. I have arthritis and bursitis in my hips so I tossed and turned all night before buying this. I was really worried because I am such a hot sleeper and sometimes sweat in my sleep. Not a problem at all with this mattress. So glad I bought it. Worth every penny. I wake up rested and refreshed for a change.

    • 4 Lbs.? I don't think so

      Bought this topper to replace a too soft 3 lbs topper. It is softer than the 3 lb.No support at all- you "touch bottom" right away. Also tended to remain compressed after I got up and got lumpy and misshapen after a few weeks. I freecycled it. Maybe someone will use it for a pet. As others have mentioned, these are nigh-on impossible to return because it is difficult/impossible to re-compress and repack. When you are talking queen size, you are talking about considerable weight as well. Wish there was a way to try these out first.

    • Once again, there is a discrepancy in the information listed in the product details section and the information provided here by Overstock's customer care. The Overstock answer below reports that this item is not made in the USA, while the product details section is clearly capped off by a big red, white, and blue "Made in USA" seal right at the bottom. Soooo? Which answer is right this time?

    • Is there a warranty on this product? How long should it last?

      • Wonder if no answer means there isn't a warranty?

      • We''re sorry, but this mattress topper does not come with a warranty.

    • Does it matter which side is placed down/up?

    • I just received by topper and it's upwrapped. But because I have to sleep in the day and work at night, do I really have to wait until tomorrow before I can use it....I would love to rest on it in an hour or so?

    • I am looking for something that is soft, can you tell me what is the firmness number?

    • Does this memory foam mattress pad come with a cover? Hopefully that is washable?

    • Does it have a (possibly toxic) flame retardant? If so which one?
