    • The most comfortable mattress topper!
Size: Full Style: 3 Inch
Every time i sleep on this i have the best sleep. My boyfriend has scoliosis and it helps his back so much. I love the cooling effect, it wraps around your body so well for cooling back/neck support.

    • Great buy!
Size: King Style: 3 Inch
Excellent! Love it! I ordered a 3” gel mattress pad but actually received a 2” in error. I decided to just keep the 2” so Amazon credited me the price difference. But I just love the feel as I climb into bed. It just feels so comfy, firm but squishy! Very happy with my purchase.

    • Comfortable but maybe not cooling....
Size: Queen Style: 2 Inch
I bought the 2" queen topper. It came in a box and rolled up in plastic. I opened it up and laid it flat for the recommended 24 hours. It had absolutely zero smell, which I was pleased about. I added it top a firm mattress. It did make the mattress more comfortable! However, I definitely don't think its cooling advertisement is correct. I am never hot over night and found myself sweating twice! I'm hoping it's the new bedding I added instead of the topper and will try just a sheet tonight. I will update my review if that doesn't help. Overall, nice product. Fits on my queen mattress well. It was easy to lay out on the bed - though it does move a little when putting tight sheets over it. Definitely improved the softness of my very firm mattress! ... show more

    • So comfy I could cry
Size: California King Style: 3 Inch
This mattress topper is so comfortable, I bought it for our Cal King sized mattress that is unnecessarily firm. It fit perfectly, it was easy to put on the bed, doesn’t have an overwhelming odor, and it’s SO COMFORTABLE. Feels like a cloud. Definitely worth the money.

    • Excellent product!!!
Size: King Style: 3 Inch
Even better than described! I can’t even remember the last time I had a good night sleep like I do with this mattress topper! It is super thick and very comfy hubby and I have both had back surgeries and it is fantastic for back support!

Size: King Style: 3 Inch
The intent of this mattress topper was to help soften the firmness of my mattress as my mattress causes me lots of pain when I slept on my sides, mainly my hips . It has been about a week since I slept on this mattress topper. Not only the pain on my sides has not changed, but I have gained additional pain on my shoulders, which is excruciating. My neck is super stiff with a constant headache. Overall, I am in more pain now than I was 1 week ago. I tend to sleep in the middle of the bed. The mattress topper is slightly indented already. To seek a little comfort, I start out on one side of the bed and slowly moving across the bed in the last 3 nights. Tonight, within 4 hours I trekked across my bed and now I find my couch provides better comfort than my bed. This couch has been in the family since the 1980's. Sleeping on this mattress topper has been worse than sleeping on my firm mattress. I don't even know how to return this mattress topper. It's bulky. I will probably have to cut it up into smaller pieces to dispose it in the trash can over time. I guess it's better to spend the money to replace the entire mattress than to waste money seeking out different mattress toppers. I truly fail to understand why this mattress topper has so many high reviews. BTW, I am 5'4" and weigh 123 lbs. Therefore, I don't think my weight has anything to do with how the topper fails to support my weight and already has a slight indentation. ... show more

    • So comfy!!!!!
Size: Full Style: 3 Inch
The media could not be loaded. I don’t know about the cooling gel because of the fact that I use fleece sheets like those plush covers that are really fuzzy and furry my sheets are like that. So they’re meant to hold heat. I have a thing about fabrics and them touching my skin and so I’ve always had sheets like this. I can’t tell you that when I bought it I think it was only 80 bucks versus now it’s a lot more expensive but it is so comfortable. I’ve had it for about a year now and I just flipped it for the first time because it was getting a little flat. However, you’re supposed to flip them I did get a full size and it did not ever extend to the full size of my mattress. It’s about 2 inches short long ways and about a half an inch short from the side to side. They half an inch is easy to make it look like it fits because I can make it to where it’s a quarter inch on both sides but I hide the 2 inches that it is short long ways with my pillows so I guess it still works out, but I wish it would’ve been the size I ordered! Everybody said give it a day or two, but it’s been over a year and it’s still hasn’t got to the full size it’s supposed to be however i had a 2 inch one 40 buck memory foam mattress prior to this that got like 4.8 stars and this is 1 million times more comfortable! It did have a little smell to it when it came out of the package but that went away very fast. I should put in here I went through a depressive state from loosing my fiancé where I was constantly in bed for about four months out of the year, the only time I was out of bed was when I was at work so I would say this mattress has held up pretty good ! I have a lot of back problems! I’m 30 now, but when I was 17 years old, they said I had degenerative disc disease which runs in my family and I had three herniated discs from my car accident so I dealt with back pain for about a decade and a half now … this memory foam topper has helped so much!!!! ... show more
