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.

This is the BEST memory foam mattress topper I've ever had. I bought a 2 inch in a twin for a cot we were using as an extra bed and everyone went crazy over how comfortable it was. I loved it so much I purchased this one for my full size bed, but in a 3 inch. It is a total game changer. I want one for every bed in the house. These toppers are excellent quality. They come rolled up, but take no time before they are to size. They do not have a bad odor like most others tend to. I have had improved sleep and it has helped my hip and back pain so much. I wake up feeling better. The 2 inch is great, but I'm loving the 3 inch thickness. It seems to support me a bit more. It's such a great value and worth every penny! I LOVE this topper!

I was hesitant that this would make the temporary use of a rock-hard mattress doable, but I needed a solution in a hurry. After giving it some time to poof up after being compressed in the box, it turned out to be quite a generous size and very thick, quality foam. Even better is discovering how comfy it is. Supportive, yet soft, I have had really good sleep since it arrived. Two thumbs up!

I bought this mattress topper as a surprise for my son who just returned home from being deployed in the Navy. I wanted him to have the most comfortable bed possible, and this topper delivered beyond my expectations! My son absolutely loves it. He told me he has never slept this well before - he doesn't even want to get up in the morning! After everything he's been through during deployment, seeing him sleep so peacefully means the world to me. The topper was incredibly easy to set up. It came well-packaged, was simple to unpack, and took only about 2 minutes to put on the bed. The 2-inch thickness is perfect - not too thick, not too thin - and the quality is excellent, especially for the price.No bad smell when we open it. We're so impressed that we're planning to buy another one for him to take back on the ship when he deploys again in November. If a product is good enough for a Navy sailor to want it on deployment, you know it's worth every penny! Highly recommend this mattress topper to anyone looking for affordable comfort and quality. It truly made a difference in my son's sleep and recovery. My son also said he is pain free.

My bed SO MUCH MORE COMFORTABLE now! Adding this mattress topper was the best decision to make for better sleep! it’s comfortable, easy to put down, and doesn’t really shift while you sleep! It doesn’t cause ANY pain whatsoever and it’s not too thick to the point where it’s really noticeable. I’m glad I chose the 2inch!

My son loves this mattress topper. For Christmas last year he said he wanted a hotel bed. I got him this topper along with other things and he was so excited. It is soft yet firm if that makes sense. It is super stable on his twin bed. There was no smell when it came out of the package. It does not make him feel hotter or colder. He just tells me all the time how comfortable his bed is. Im going to buy one for myself this year.

I LOVE this mattress topper! I had been uncomfortably sleeping on a dorm air-mattress and knew I needed a change. This was 100% worth the money and perfect for college students. My bed is super comfortable now. I used to wake up with neck and back pain, but I now feel relieved and energized waking up. I actually let it inflate for about 8 hours, then went ahead and put it on my mattress and let it finish inflating on my bed. I haven’t had any issues with it sliding off since I got the option with the straps.

Some of my reviews are quite severe when I'm disappointed with a product, but in this case, it's all praise. Absolutely no odor, true memory foam, superb comfort, does't make the bed hot, the physical appearance of the foam out of the box was perfect -- no nicks, tears, nothing. At this price point, I can't imagine doing better. (PS: Instructions recommend leaving it out to expand for 24-48 hours, but I found that unnecessary -- it plumps up almost immediately.)

After about 6 weeks: Nope😕 I thought this was great when I got it, it feels comfortable but my pain after a month really increased. I have fibromyalgia so I thought was in a flare, but then I realized the topper was making me sleep in ab unbalanced alignment. I took it off and started feeling bit less pain. I really wished this was gonna help, but sadly made me feel worse. It seems to relieve pressure points but it really just gets you settled into a poor sleep position and your still resting on a too hard surface. I had pain in new areas and ultimately figured out it was this topper. So money wasted, again. (First impression: his worked! It's dense so gives support, slow rebound foam. Conforming so no pressure points, but supports so easy to turn over in bed (not mushy at all) I weigh ~110lbs, got the two inch. If you are under 150lbs, do not get more than two inch. Got the 3 inch for my 100lb mom and it was very very firm. Obviously better for a heavier person, but 100lbs just wasn't enough weight to be able to sink comfortably into it. If you want firm, serious firm then 3 or 4 inch will work for you. Makes me slightly warm at night but no where as much as my old foam topper did. It had no smell and opened up on a spare bed to full in about 1 hour. Very happy with the 2 inch just do not think more is better with this one, I honestly think 1 inch would have been fine for me but did not want to bother to return it. I got the twin, and it was about inch wider than it should be, so I had trim it. ) Money wasted, can't return by the time I realized this thing was causing the increase in pain.
