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

Great mattress topper. Good quality. Fits well. Stays in place. Right firmness and conforms to my body. Was afraid to order because of back pain but it supports my back and does not cause any pain

When I got the pad, it came in a small box. I opened it and thought…..”I hope this is the right size “ I really didn’t want to unpack it and find out it was the wrong size because I knew I’d never get it back in the box. So, if they want to improve anything, they should either enclose a packing slip or print the size on the packing. I had read all the reviews before buying it, so I knew it came shrink wrapped, so I opened it. I unfolded it,( saw it was right),and spread it out on the floor to “inflate”.It didn’t take long,I was very impressed after I put it on my bed, it looked great and it felt even better! I have a thick mattress, and I was glad I got a 2” but I was happy that the sheets fit and the 2” was perfect! It feels wonderful and I slept much better ! It really helps my back pain. Great product at a great price! Get one, you won’t be disappointed!

Review updated 10/2024 after great customer service interaction initiated by the seller.The pad, the cover and the straps are all well made. With our tall mattress (14+) the straps don't hold the pad in place as well as we would like. If all we did was lay there unmoving, it would be fine. We find it to be between plush and firm. As a fix for our issue I will attach straps under the mattress diagonally to hold the pad straps in place.

I’ve been having some neck and back pain so decided to try this after reading the reviews! One thing that was really important to me is there would be no smell and they’re absolutely wasn’t. I took this out of the box within a few hours. It was puffed up and perfect. It’s so comfortable and makes a huge difference. If you were thinking of getting one of these don’t hesitate this one is amazing! From someone who’s going to be sleeping a lot better from now on!

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!

Takes about 24h to inflate. Very comfortable sleeping since I got the topper, no back pain. Unfortunately it is a bit smaller than queen size and slides very little.

I received this item today, opened it and put it on the bed and put the bedsheet on the bed. It says it takes 48-72 hrs to fully expand as it is vacuum sealed. Well let me tell you, within less than 30min it was already fluffed up and feeling wonderful! If it keeps expanding it will just get better. I needed it for a twin size bed and I got a 4 inch mattress just guest coming this weekend and when I sat I could feel the bars of the frame, i didn’t want to buy a box spring. This arrived and it feels like heaven! I cannot feel the bars at all anymore if I sit on the bed, and it’s superComfortable overall! Buying one for my queen size bed! Arrived quick! Ordered yesterday evening was delivered by the time I got home from work today.

I live everything about it. It fits perfectly. The big straps makes it never shift and it feels heavenly.

Muy cómodo y fácil de usar

This products matches very well with the description. It’s also comfortable. BUT, every week or so, it shifts away and must be manually centred back on the mattress.Will add some velcro to try to solve this issue. The elastic straps in the corners help, but not strong enough and can’t be adjusted.

I have a problem about spring mattress because eventually it lowers and sinks in, resulting to q back paon. UNTIL I PURCHASE THIS. honestly, even this topper alone and a solid flat floor. My sleep was wonderful and less backache.

Me encantó! Nos regalaron un colchón King que estaba durísimo durísimo así viejito. Y con esta colchoneta se siente ahora como un colchón premium, súper cómodo, descansamos delicioso. Es la mejor calidad y precio que encontré en todo el mercado

عجبتني صراحة.. في البداية كان فيها ريحة خفيفة لكن اختفت خلاص ومريحة جدا
