SINWEEK 2 Inch Gel Memory Foam Mattress Topper Twin Size, Ventilated High Density Pad for Back Pain, Bed Topper with Removable Soft Cover, CertiPUR-US CertifiedOEKO-TEX STANDARD 100

I bought this for my daughter to use on top of her dorm mattress but she hasn’t slept on it yet so I can’t really review the comfort yet but it seems very soft. I primarily wanted to address the comments that mentioned problems with it expanding. I just took it out of the packaging and laid it flat on the floor and the next day, it was fully expanded on its own. You just have to be patient and let it do its thing. You won’t be able to sleep on it immediately out of the box. Hopefully that helps.

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!

I was having big time back problems due to our mattress being too stiff. This pad seems to have fixed the problem as it contours around the spine not leaving any unsupported gaps. Right choice for us.

Very comfortable. Helped with my wife hip problems.

It’s incredibly comfortable. You sink right in, and it honestly didn’t take that long to expand. There’s no smell either. It’s even bigger than my full mattress size, just by a few inches.

Excellent product. It arrived perfectly and works very well. I recommend the seller.

Very comfortable. Easy to work with.

Good mattress topper, helped improve my sleep. It’s reasonably thick and made my mattress easier to sleep on, fairly comfortable.
