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

So let me just say, I never write reviews… I bought a brand new mattress a few years back and I got a firm mattress. Thinking that was the best option. I have had years of back pain and sleepless nights since. So I was thinking about buying a new mattress. I really didn’t think a mattress topper would help my problem. BUT IT DID!!!!! I cannot even believe it!I really really really didn’t think it was gonna work. But with Amazon… I know I can always return. So I figured I’d give it a shot. I decided to purchase this one based off the reviews. There were so many positive reviews. And it was the first one I looked at! So I got really lucky.When you get it, and you take it out of the box… You have to lay it out. It expands immediately. On the edges of the top and bottom of the mattress topper, they needed a little help. I just carefully and slowly pulled the edges. As soon as air is able to get in there… It does the rest.But be careful! It will rip easily… I cannot even believe how comfortable and cozy my bed is. And no more back pain! Wow. If you’re thinking about getting a topper… I’m telling you, get this one! I’m seriously shocked. Because so much stuff you buy these days just doesn’t do the job it says.

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!

Bought this during pregnancy for more support and cushion. I slept amazing the first few weeks with this product. It’s easy to assemble on the bed with the straps to hold it in place on the mattress. This product has more cushion than support and tends to sink in when laying down. Overall this is a good alternative for an affordable mattress topper if you’re looking for something not too hot, minimal support, and average cushion.

We bought this for our travel trailer and it worked perfectly. Nice cover, and expanded quickly. Very comfy.

Arrived rapidly, and in a small box, I unpacked it and laid it on my queen size bed and I thought oh no this is never gonna work?I went back a couple hours later and it was completely puffed out more than covering all of the edges of my queen size bed. This topper has made a wonderful difference in my sleeping. I love this product. . It comes with a zip cover that you can wash and it has beautiful elastic bands that stretch all the way below my mattress to keep the product on my bed had never slipped off. I think it was a fantastic investment , I am sleeping so much better. The product arrived with no smell whatsoever, and within a couple hours was the wonderful topper that it is completely filled out. I have the 3 inch depth. I don’t think I would want more or less. One of my best purchases. Very cool sleeping on it at night. It has added no heat to my bed gives me Wonderful support and zero smell.
