ZINUS 1.5 Inch Swirl Gel Cooling Memory Foam Mattress Topper, Cooling Airflow Design, CertiPUR-US Certified, Twin

I bought this for my son's bed in our camper. It seems a good quality, had very little odor that disappeared quickly. But, if I were to do it again, I would go a half inch thicker. Purchased the 1.5 and with the peaks and dips, the dipped portion is very thin. He said it did add a smidgen of comfort.

My golden retriever really likes it as he sleeping all night long and snoring. So i guess it's a success. I needed 1.5 " at most for pullout couch. makes a world of difference in comfort.As for the "cooling memory foam" I would say it probably is cooler than flat foam toppers but it can be warmer than just a mattress. it's not a problem as i just use less covering.

I've had the 2 inch for about a week now. Before you open the box decide where you'll be laying it down to fully de-compress which takes roughly 24hrs. You need to be gentle with it when you take it out of the box and begin to unroll it while it is still in the plastic sheeting. It comes folded in half and then rolled up so it looks small. I gently cut the bottom of the sheeting and it started to expand a little. I slit it open along the edge of one side to let it expand. When I tried to separate the foam (it is folded in half) I found it sticks together. If you're not careful it can rip. I did it a little at a time every 10 minutes or so as it was expanding. Eventually I cut along the other side of the plastic sheeting and unfolded the plastic which made a large sheet of plastic that was protecting it from my living-room floor. You need to let it lay somewhere to fully expand so plan in advance where you will do that...best to have a spare room away from kids or pets. You could put it on top of an old blanket or a drop cloth if you don't want to take the time to open the plastic the way I did though.When I put it on the bed the next day, I was surprised how the 2 inches made it actually harder for me to get into my bed so BEWARE of that if you have thick mattresses or are buying it for an older person. I really can't sit on the edge of the bed anymore like to put on socks without a struggle. I'm 5'3"It seems pretty comfortable compared to having the mattress poking me....but then again, I finally got around to rotating the mattress and that could have helped too. I put this foam pad over my regular mattress pad. I knew there wasn't going to be enough room to put it underneath and I saw some questions about the product where people wondered that. There are no instructions on the subject in the box but there are 3 blank greeting cards in there? One is a thankyou card you write your own message and two Hello you blank cards. They seem very high quality for cards but without envelopes they are pretty useless....and who really sends out those cards anymore? I felt a little guilty throwing them out but I am trying to fight my clutter habits. Although I guess it was a nice gesture, it seems wasteful to include them.Laying on the bed feels nice. I do sink in after a few minutes but it is still comfortable UNTIL I start tossing and turning which I do often. My problem is it somehow makes it a little harder to support myself with my arm to flip myself. I've been having some shoulder pain in the mornings and it could be that or many other things but the truth is every night I start off saying this is really nice and every time I get out of bed I say I don't like it. It is a cheap fix to an uncomfortable mattress. Because it's hard for me to dig my heels in or my arm into the mattress to turn myself, I can only guess that is why some people say their pad ripped. Just wanted to give a review because I find reviews very helpful when shopping. Something to consider if you are buying this for an older person or someone with a disability.

I purchased this mattress topper to replace another one that made me so hot that I basically wasn't sleeping. I thought it was just perimenopause, but thought I'd blame my topper before I blamed my hormones, and as it turns out, I was correct.After reading a ton of reviews, I opted for this product because of the lack of mention of people sleeping hot. I saw several reviews mentioning that the topper didn't fully expand, but I figured I'd take my chances. Note that I've used memory foam toppers for every mattress I've owned over the last 20+ years, so I'm not inexperienced with how they feel and behave.When it arrived, I was impressed by how compact it was, but surprised by its light weight. I removed it from the box and bag and allowed it to expand over a period of about a week in my guest room because I was too tired and lazy from lack of sleep to strip the bed.Once I did finally get it on the bed, I was again surprised that the feel of this topper was much firmer than any others I'd previously owned. The only way I can describe it is that lying down on it initially feels like you're resting on top of a block of floral foam. If you've ever felt that substance before, it's quite firm - almost hard - but then gives way to gentle pressure. The difference is that floral foam will stay indented, and this topper returns to its original shape......or at least, it's supposed to. I've found that this pad tends to stay very compressed and flat in any areas where there is a significant amount of pressure (so for me, as a back and side sleeper, under my bottom/back, or under my hips/shoulders) for significantly longer, meaning that if I sleep in one area on my back for a while, then roll over onto my side, the divot from my back sleeping makes my body want to roll back into it. It's very strange, and I've never seen memory foam react so slowly before. It does a decent job at cushioning pressure points, but the area under my butt gets so compressed (like compressed to the point that it feels like it's fresh out of the package) that I might as well just be lying directly on the mattress itself. The other issue is that there is a portion of one side of the topper that has a bulge between 2 slopes, as well as a pointy part that sticks out away from the edge of the topper. It's difficult to explain, but it's definitely a manufacturing defect. It took me several days to notice it because I initially thought it was just a depression where I'd rested my knee near the edge of the bed, but when it persisted, I took a closer look and realized that it was an issue with the topper itself. And now the thing essentially can't be returned because it will never fit back inside the box it came in.On the plus side, I sleep SO much cooler than I did with the last traditional memory foam topper. Once upon a time I had a wonderful topper from Costco that didn't make me sweat like a wh*re in church, but every one since then has increased my sleep temperature to some degree (degree...get it? Get it?) so in that regard, it's...comfortable?Would I buy it again? Uh, no. Manufacturing and performance are questionably low, but if I ever need a piece of foam to mold to the shape of something, never to return to its original form for shipping or something, this would be my first choice.

It is very comfortable to sleep on. The temperature and firmness help myself and my husband stay asleep. The size fits my bed and I have a king sized bed.

Me sorprendío el cambio despues de ponerla en mi colchón, muy cómodo y excelente para descansar

For the physically impaired such as myself, it provides enough hip support to not wake up in pain. My partner has been accepting his creaky spring mattress and didn't even realize toppers were a thing. He doesn't wake up sore and grumpy anymore. Best $40 I ever spent.

Product was delivered very late and product was stained. Not enough return time for damaged product. Was expensive . Unable to use the product. Like to return get credit or exchange product

Arrived on time great to sleep on

Too hot
