    • Not great

      I bought the topper and it's really not great. I laid on it and sank into it. I was basically stuck. Trying to lay on my side was almost impossible. It caused me to get a lot of back pain. I was forced to remove it 2 days after use

    • Very cushy but still too hot

      This topper is very soft and comfortable. You sink way into it which makes it really hot. I was hoping the gel infusion would help with the heat, but it doesn't seem to make much difference. I love the comfort but had to take it off my bed last night because it is too hot to sleep in/on.

    • Do Not Bother To Buy This Mattress

      Way too soft and feel like a regular foam, not like a memory foam at all. I regret to buy this brand versus the brand, *****, that I used to buy. Huge different. I used to have really really bad back pain and ***** supports my body so well that I can sleep well but Beautyrest does not. If I can, I will return it and I am looking for way to return it. Hope it helps, Ken

    • Worse sleep of my life!

      After reading the reviews on this product I was convinced this mattress topper would be the answer to my prays... I was so very wrong! I have never experienced such discomfort while sleeping in my life! I can not accurately put into words how much I detest this product. The only way I can sleep at all is by putting small cushions under my body to help support and distribute my weight. The pain this product has caused my body is indescribable. DO NOT WASTE YOUR MONEY!

    • Excellent

      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

      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.

    • Back is now resting comfortably!!!

      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.

    • My order was estimated to be deliveried on May 12, 2015 and all the sudden I realized the tracking system said it was deliveried on May 04, 2015 but I never received it. It said it was left at the front floor but my place is a gate community and I was never called to wait for the package at home. Can Overstock pay me back as it was never deliveried to me.

    • 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.

      • better topper
