SINWEEK3 Inch Gel Memory Foam Mattress Topper Full Size, Ventilated High Density Pad for Back Pain, Bed Topper with Removable Soft Cover, CertiPUR-US Certified

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!

The only negative I have is that it’s not the same as my last one and that’s a positive and negative. My last one came from Walmart but wasn’t their mainstays brand I think it was ‘Allswell 4in’ whereas this one is 3 inches which I can feel. It’s also firmer and softens as you lay down, it really does feel like your sinking in at first. I do like that this has the straps unlike my Allswell, and has the protective cover already on it instead of fitting over it like a fitted sheet like Allswell. Overall I’m satisfied, it still turned this 7 year old hard mattress into a mattress that is actually comfortable. It’s a great alternative until I purchase my house and buy a sleep number or something lol.

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

Very comfortable. Helped with my wife hip problems.

My mom is on Hospice & the bed they brought to my sisters place where mom is.....was a hospital bed with a thin plastic mattress. After this came I played on it & was fantastically comfortable!!! Mom has been sleeping very well. So this nite my sister & I got mom into the bed the first thing she said was it feels good. She slept all nite & longer into the morning without body pain.

Nice fit well made took about 12 hours to fully rise.I find it pretty comfortable to sleep on.Arrived on time.

These mattress toppers go perfectly on College dorm mattresses as most people know the dorm mattresses leave little to be desired. We have a college athlete who really needs to take care of her body and this mattress topper has helped her rest well while she’s at college!

It’s a little wider than a hospital bed but we can manage that.Very comfortable over air mattress with baffles.
