      I was worried that the memory foam would not be awesome. I was wrong. It is awesome! It took a full 48 hours to expand. At first, it was like regular foam. It is a dream now! I highly recommend this item. I look forward to my king size order as well.

    • Nice Quality Mattress Topper
      Verified Purchase

      Very pleased with this purchase; I was on the fence because of the price but saw it had much better reviews than other similar ones; when I unwrapped it, it very quickly puffed up to full size, very little smell which dissipated quickly. Only problem I had is at 74 it was a struggle to get it up the stairs. I recommend not unwrapping it until it is placed where it will be used, as it is heavy and would be unwieldy to carry it, once it is unfolded. Slept on it last night and woke without my usual hip pain!! I recommend this product.

      I like the fact that the foam topper corrected the sag in my older mattress but it does make the overall mattress 4" thicker and although supportive, could have been a bit firmer for my preference. It does collect heat and get you hot at night. Next time I'll just spring for a new mattress!

      if you have a bad back...firm is not the answer! I bought the Casper bed and it was fine for a month then pressure points started to emerge. rather than send it back, which was an option, I bought this topper and all is great!

      I was skeptical because there were no reviews when I bought this topper, but I am so glad I did!! My foam mattress was very firm and only 8 inches deep so it looked strange on my bedframe. I was looking for something to add depth and make my bed a little softer. This topper is heaven. It is perfect for those that like the firmness of a foam mattress with the plushness of a pillowtop. However, it can be a little warm. It is not a problem for me, because I am naturally cold blooded, but even I have noticed it being somewhat hot especially on hot summer nights in Texas.

    • basically ok
      Verified Purchase

      I am overall happy with the product but with one issue. The product being "gel foam" and claiming to keep the user cool is overstated. It still retains body heat like memory foam is known for. This effect is somewhat lessoned with the gel technology but not eliminated. It is very comfortable otherwise. In the cooler months with probably be great. I would recommend it with the caveat that it will not stay cool in the warm months.

      Verified Purchase

      This is a great alternative to purchasing another new mattress. My current mattress is 1 year old and never "made the cut" of being comfortable for my back. My normally sore lower back is now resting comfortably. I would definitely recommend this product.

    • What is the shipping weight of this topper?

      • Hello mtdreams, the ship weight is approximately 14.6 pounds. Thank you for shopping with us!

    • When they say "cover" is it just around the topper or is it a skirt to tuck under the actually mattress so the topper does not move. Is the cover removable for washing?

      • Hello Allensia, this includes a cover that will enclose the mattress like a sheet, it is removable for washing. Thanks for shopping with us!

    • Why did you choose this product?

      • to relieve pain when I wake up. Please if no one home, leave at back door of house.

      • Topper for Posturpedic memory foam mattress. Will add layer of cooling and softness. Like prices here.

      • Recommendation of a friend who purchased this item from

      • I have tried other toppings and have not found one that is good. I have heard about the gel toppings and that they do not get warm.

      • Seemed like a nice addition to my bed.

      • We ordered a Serta Memory Foam Mattress several years ago and it said the dimensions would be 52" wide. It arrived and was comfortable but it was only 49" wide for a Full Size. This one claims to be 53"wide and hopefully it will be what it says. If it was for just one person it wouldn't be too bad but there are 2 of us and that makes it considerably smaller than a Full which is small already.

      • i have horrible back problems, spondylolisis, scoliosis, had spinal fusion surgery, and the mattress toppers are an affordable way to help me sleep comfortably. i also can not stand to be hot while i sleep, so i thought i would try out the cooling gel memory foam.

      • Because I need to not hurt and be able to sleep good

      • I have a California King Size bed that the foam that goes in the pillow top of the mattress... is old and I am trying to see if this Mattress topper will fix the problem. If not,,, OUT the back door the mattress goes.

      • Good reviews

      • Because of the name brand, and also from recommendations from relatives and friends.

      • Combination of features, reviews and pricing.

      • We had purchased one for a double bed in the guest room and our guests like it. However,that one came with a polisilk cover, so the waterproof cover is a new feature for us. We hope the cover is comfortable and that it is really waterproof.

      • My son has a Gel mattress topper and he strongly suggested I get one. After shopping around I decided on this one with waterproof cover. I wake up and in less than 2 hrs, my mid back hurts and I can only contribute that to the old mattress on the bed.

      • To put on top of a very firm mattress, to give it some softness on top of support.

      • Waterproof cover

      • I have one on my bed and love it so much I had to get one for my camper

      • Because my boyfriend is constantly complaining that he's hot and that my mattress is too firm for his taste, so I want him to be more comfortable. I really hope this works.
