      Sure wish I could find it for the price I bought it for a few years ago. It was excellent, so comfy and held up well. I carried it to my costa rica home and loved sleeping on it. It was repurposed for chair pillows and is still being used in smaller pieces.

      I purchased this item 6 or so years ago and it was time for a replacement. I went into my order history and purchased the same option again since we were so pleased with the original, but this wasn't the same topper. The quality wasn't the same, it began to easily tear and we finally just pulled it off the bed altogether. We won't be purchasing again.

    • mem-cool exceeds claims.
      Verified Purchase
      Option: Queen

      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
      Verified Purchase
      Option: Queen

      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
      Verified Purchase
      Option: King

      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
      Verified Purchase
      Option: Queen

      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.

    • Q:

      "is the topper CertiPUR certified?"

      • A:

    • Q:

      "Can this product be returned if it is not suitable?"

      • A:

        Once open this product cannot be returned.

    • Q:

      "Could you tell me if this is as firm as the same brand one that is not "Mem-Cool"? The wording on the description of the composition is totally different. This one says, "99 open cell configuration for maximum heat dissipation 10 times the air flow of other memory foam" The other one states it is a "Made from high density 3-pound solid viscoelastic memory foam". So this is confusing to me... I want to order two of these right away... but want to be sure the "Mem cool" one isn't going to be the kind that you sink to the bottom of it either immediately or even a couple of years. I have had the other one for over 10 years and it is just now getting spongyish!"

      • A:

        This topper was the first one I ever got but it also will be the last one. It is so heavy and easily damaged. It is way too soft, to the point it makes to hard to move around or to get of the bed. It did make me hot and sweaty to the point that I went out a purchased all new mattress so I would not have to deal with it. Total waste of money.

    • Q:

      "We have a sleep number bed where each side at the head of the bed can be raised independently. Can this type of topper be cut into to allow the top third of the bed to move?"

      • A:

        Yes. It can be cut.

    • Q:

      "Does the topper come with a cover?"

      • A:

        The topper does not include a cover.
