SINWEEK 3 Inch Gel Memory Foam Mattress Topper King Size, Ventilated High Density Pad for Back Pain, Bed Topper with Removable Soft Cover, CertiPUR-US Certified

I was surprised at the smudgy comfort (for lack of a more distinguished word) of this topper. We were visiting our daughter and I have a shoulder injury and her bed was stiffer than ours at home. It set for 4 days before we arrived. Just couldn’t believe how nice and cushy it was. Definitely recommend. Worth the money and better sleep quality.

I've seen reviews that this thing won't expand to it's intended 2 inches, or at all for that matter. I witnessed that as well. But I really didn't want to return this item. So I dinked with it.You gotta stretch it a bit- GENTLY- bc it will rip between the holes on the surface. Not it's fault, I was over zealous :PIt's really separating itself from itsself so it can let in the air. It's a bit like moon sand when it's that compressed. After it takes it's air, it doesn't stick to itself anymore. I had mine in sleeping order within an hour and it. is. so. COMFY!I don't even like memory foam because when it first came out years ago, it would hold the shape of my body indent. This does NOT do that! I have a bad back and huge bo@bs, so I can't sleep on my back, or my tummy, but when I laid down on my bed with this topper before bedtime, to check how it felt, just on my back... I was so comfortable I feel asleep right away! The lights were still on and everything 🤣. I only woke up because my daughter was like, "mom, what are you doing?!" I didn't put her to bed yet lol. I just wanted to try the topper after I made the bed. And I don't like the idea of a 'cooling' topper, but it's not what I thought..... I always wake up sweaty, always. And today, I didn't!!!! My bed was warm and snuggly comfy right when I got in and throughout the night but I didn't sweat like I usually do!!! AMAZING!!! And I usually wake up several times through the night, but I don't remember waking up once!!! I just realized that!! I am excited to go to the bed now... How awesome. Don't give up on it right away. This'd is an excellent deal! No weird smells either! Usually there's some kind of chemical smell with these kind of things, not this one. I didn't smell anything at all.You can stretch it but standing on one end and pulling gently on the other end. Just enough to separate itself from itself inside (I took the cover off). The corners need you to use your fingertips and pull the back away from the front, kinda thing. Gently and slowly. You can even hear it letting go of itself, then watch as it does that moonsand thing... You can see it expand right then. Looks cool. I didn't measure mine, just let it litter there a few minutes after releasing all the wrinkles and creases. Comfy!!! My daughter wanted me to order another one just for her to play on in the living room :p I actually rolled across it to avoid crawling when I was putting the cover back on (the zipper is missing the dangly part on all of them I think, on purpose. Just grab it with two fingers on front and back to zip/unzip) and also to make my daughter laugh) My big body did not hurt a bit doing those rolls. I anticipated my spine grinding on the floor underneath the topper since I'd just finished releasing the wrinkles, and I'd only had the thing in possession for an hour (I opened it immediately to give it the anticipated time of 48 hours to expand). After a half hour I checked on it, and it hadn't changed a bit. That's when I decided to dink with it.I recorded some video but don't know if I'll use it since I was huffing and puffing because I'm a fat 🤣. Jk. But I am 😁I just realized!!! I didn't struggle to get out of bed either!!! I usually wake up wracked with pain!! (Bad back/prev surgeries and procedures). I'll have to pay attention better tomorrow, because that's A HUGE deal!! I'll update if I remember... Wow. So cool!

This is a super thick mattress topper for a twin bed that greatly increases your comfort level. Love the soft quilted top cover that can be zipped off for cleaning. There are also wide elastic straps that help to hold it firmly in place on the mattress. The cover also helps to decrease the heat retention of the foam, making it more comfortable on hot nights. There was some plastic smell when it was removed from the package, but that quickly went away when aired out and allowed to decompress from the box. If a too firm mattress is hard on your back, you will love this thick topper.

I bought the 3 inch pad for my standard mattress. It takes quite a bit of getting used to. At first I had a struggle turning over, as though it were holding me in place with its extreme softness. Gradually I adjusted to that new experience. The wonderful thing is that I am now waking up almost pain free. I am 89 years old, have severe osteoporosis and am wracked with painful arthritis. I had reached the state where it took a couple of hours in the morning to work the kinks out, and staggering to the bathroom in the night was difficult. Now after three weeks with the memory foam pad, I am so much more mobile. One problem that can't seek to be resolved is that I become very hot and sweaty because the pad holds the body heat. Heating up beneath me may be a good thing in the winter, but not welcome in the summer. However, any negative features are negligible in light of it's gentlenessto my bones.

This mattress topper was just what my lower back needed. I recently bought a new mattress for our bedroom downstairs, which I sleep in when I just need a night of undisturbed sleep. The mattress was making my lower back hurt, so I decided to get a topper for it. This topper worked like magic - no more lower back pain when sleeping on that mattress! It expanded nicely after releasing it from the packaging, and fit nicely on top of the mattress. It did not smell at all after letting it expand for 48 hours. While you do sink a bit into the foam, it doesn't let you sleep hot like the original foam mattresses/toppers used to. Would highly recommend this mattress topper!

This is very comfortable. I wish I would have ordered it sooner! Just what I wanted for my over firm mattress.

It is already 48 hours and the foam is not a proper rectangle. It "bulges" on the side (imagine an oval with the top and bottom cut off).It is comfortable otherwise.I think I might return this. It is only worth less than half of what I paid if it doesn't fit properly.

Very comfortable. No more low back ache. Fits the bed well and does not slide off edge as others have.
