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 purchased the 3” mattress topper and I was pleasantly surprised after one night. I am caregiving for my father and found the bed I sleep in very uncomfortable and would toss and turn all night due to my hips aching. The first night with this mattress topper made a huge difference! I slept all through the night and didn’t wake up with sore hips. The mattress topper seems to be made of high quality material and the firmness and thickness of it is perfect (I am used to sleeping on a tempurpedic). I am a warm sleeper and did not get hot. But it is still winter. I did not notice any bad odors when unpacking it or sleeping on it. I would definitely recommend this topper if you are not looking for a soft squishy bed.

Took a chance on a cheaper off market topper, and it paid off. I have a very bad back, and this topper has been amazing, it seems very stiff when you first lay on it, then you slowly melt into it and it conforms spectacularly to you. Also I am a furnace when I sleep and it stays cool enough that I don't wake up in a pool if sweat. Not sure if it works for a side sleepers but if you have spine issues it definately does the job and at a very reasonable price point. Pros: Conforms amazing for back sleepers Very cool temperature wise to sleep 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 :P It'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 bought this 3" topper for my king size original TempurPedic mattress (on a platform frame) which is getting up there in age, just as I am. With a bad hip it can be a challenge even on my trusty Tempur to get comfortable. Before shelling out big bucks and going shopping to find a "perfect" replacement mattress, I thought I would try a topper first. It's providing me with a nice, comfortable bed. Just the right amount of softness and support. There is no difference between my Tempur mattress with or without the topper, when it comes to heat retention. It's the perfect thickness for me. Out of the packaging, it expanded just fine. Out in the morning and slept on that night. There was some gassing but it dissipated within a day or two. My suggestions for improvement are related to the cover: 1. It comes with a zipper - but only on ONE SIDE. Try and get the cover off to launder it and then back on - on a KING SIZE topper... Not happening. So I will have to figure out how to keep it clean. Maybe steam cleaning. 2. The corner straps to keep it in place aren't set back (away from the corner) far enough to securely hug the corners of the mattress. So far it's been OK, not much movement but I think it will need adjustment from time to time. 3. The cover material is prone to get caught on jewelry or even fingernails which can create a run similar to what you get with a panty hose. I recommend taking off your jewelry and checking your nails before handling the topper. Beyond that, you really can't beat the price, especially with new & used offers typically around $100 for the King size 3".

I would give this product 10 stars if I could. I’ve purchased about 3 mattress toppers including this one and none of them have been as comfortable as this one. Thereabouts ones I purchased break easily since it doesn’t have a cover but none the less cost about just as much. This one is true memory foam. Some others reported that it doesn’t rise but mines rose to 2 inches within an hour. I love the straps as it doesn’t move around like others and love that the cover makes it easy to wash. Highly recommend at this amazing price point.

The quality is really good, the only thing i didn’t like is the size is not really standard, 78x80 inches (198x203 cm ) it comes like a square l, so needs to be cut somehow to be fit for 180x200 mattress

Very good topper, i bought it for my truck and very comfortable not too soft or hard take your body shape to relax your joints. No heat issue.

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.

Works perfectly for our needs. We use it in the guest bed

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
