Features

  • Nylon
  • GEL MEMORY FOAM MATERIAL: Our memory foam mattress topper readily conforms to the curves and shape of your body, distributes weight evenly to alleviate pressure points for better sleep.
  • MORE COMFORTABLE SLEEP: The gel memory foam material used in our mattresses reduces heat and improves the airflow to refresh the gas permeability; add to the mattress for custom comfort.
  • SOFT BUT NOT FOLDABLE: our mattress is soft, do not roll up and store too long after opening, and do not put items on top, which will increase the risk of tearing.
  • CertiPUR-US CERTIFIED: Our Gel Swirl memory foam topper is made of CertiPUR-US certified materials. The Gel Swirl memory foam topper meets or exceeds standards for content, emissions, and durability.
  • BEFORE FIRST USE: leave the memory foam flatly in a well ventilated area for 48-72 hours until it's fully expanded. In addition, we offer a three-year warranty and 24-hour manual customer service to ensure your after-sales service.

  • Great product!
Color: 3 Inch Size: Queen
I bought this because of my husbands back pain when he wakes up in the mornings. It has worked pretty well but there is still some back pain. I can say it was comfortable but hard to move around. I have to raise up my body in the bed just to move in another sleeping position. It is comfortable but hard to move around on. ... show more

  • Makes my bed SUPER comfortable!
Color: 4 Inch Size: Full
I am SO GLAD that I purchased this memory foam mattress pad! It has added a much-needed layer of cushiony comfort to my bed. The first time I slept on it, I don't think I moved all night! I love how I "sink in" to the memory foam, but the limited depth probably makes it easier to change positions than a full memory foam mattress would-- and this is much more affordable! I also appreciate that it doesn't make me any sweatier than I already get at night (I'm a "hot sleeper"). This is one of the best purchases I have ever made for a bed, and I am very glad to have it. ... show more

  • Great topper
Color: 2 Inch Size: Full
I bought the 2inch topper and gave it three days to plump back up. I was a little concerned because some reviews said that they received toppers that were too small or weren’t cut straight. The topper I received is about 1/2 inch larger on each side than the bed, so I was happy with the size. And as I said, I gave it three days to plump and it came out great. It makes the bed much more comfortable. ... show more

  • great topper and makes a super firm matress feel great.
Color: 1.5 Inch Size: Queen
Great topper for a super firm Linus mattres. Provides great comfort. I suspect it might be warm in the hot summer but i have a bad back and this provides great cushion for an amazingly firm mattress that I need. It comes compressed but mine fully expanded in just about 10 minutes.

  • Great topper for sofa bed at a reasonable price
Color: 2 Inch Size: Twin
We have a twin sofa bed which has a really uncomfortable thin mattress and universally hated middle bar. This mattress topper was the perfect solution for our occasional guests using the sofa bed. It actually made for a very comfortable sleep.

  • SUPER COMFORTABLE!
Color: 2 Inch Size: Twin
This mattress topper is so soft and comfortable. I purchased this to put on the floor in between my twins boys beds. My back was always hurting when I would get up because the floor is hard, this has made a huge difference.

  • So comfortable, great value
Color: 4 Inch Size: Twin
I really like this twin sized mattress topper. When I first bought it, I was worried it was too small for my twin bed. However, after 24 hours, it fully expanded to the correct size. It turned my hard memory foam mattress into a soft cloud, and I really love it. I got the 4 inch kind, which I was hesitant about because I thought it might be too cushy, however, I’m very happy with it. It did take a couple of days for the chemical smell to dissipate, but now it’s fine, and I absolutely love it. It makes sleeping on my side easier. I also bought a softer memory foam pillow to complement the softer mattress topper. Others in the reviews have mentioned that the topper can rip easily, and this is true— it is heavy but delicate, so when you lift it to place it on the bed, be careful not to let it tear. However, now that it is on the bed, it is fine. This was a great and relatively cheap investment. I have had the topper now for several weeks, and still love it. ... show more

  • Disintegrated
Color: 3 Inch Size: King
This looks and feels nice out of the package, however it has no structural integrity and will completely start to fall apart within a couple months. update: I changed my rating from 2 to 3 stars based on the seller being nice enough to reach out and offer a partial refund.
