Features

  • 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 its fully expanded. In addition, we offer a three-year warranty and 24-hour manual customer service to ensure your after-sales service.
  • NOTE: The softness of the Mattress Topper is influenced by the temperature. In the cold winter Mattress Topper will become harder.

  • 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

  • Love it!
Color: 2 Inch Size: Twin
I bought the 2” topper and its been amazing! I was waking up throughout the night with achey hips but now with this topper that has completely gone away. Very soft! Take care of it by keeping it covered because i noticed it can start to tear.

  • 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.

  • 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.
