    • mem-cool exceeds claims.
      Verified Purchase

      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

      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

      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

      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.

    Questions & Answers

    • 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?

      • Yes. It can be cut.

    • Does the topper come with a cover?

    • What would you consider to be thec"life" of the 4 inch topper?

    • Does this topper come with a cover?

    • I ordered this topper but the one I received was blue and has a FXI warranty certificate but no proof of purchase info. I think I was sent the wrong one

      • If you believe your order is in error, please contact us at 1-800-843-2446 for assistance.

      • Mine was blue, too, which was a surprise, but it has been as wonderful as the others we have purchased. Whenever we get a new one (about every 5 years), I use the old ones for my spare bed, or cut them down for my grandchildren's 'packnplays'. They sleep great, and my daughter takes them with her on vacation.
