I have bought two of these twin Niagara cooling mattress toppers (one for me and one for my son) and highly recomend buying them as they are fantastic over a Zinus 3inch Green Tea Memory Foam Mattress topper especially since our beds are shot: like feeling some coil instead of buying a new mattress. Fits perfect for twin beds and the Bamboo Niagara topper is so comfy and fluffy. It is cooling. Slept the best after getting these together ❤️

We couldn't be happier with this Niagara Sleep Solution Ultra Soft & Cooling Mattress Topper! We already had a 4-inch gel memory foam mattress topper on our bed, and we added this on top of it. The combination is incredibly comfortable and feels like sleeping on a cloud. The mattress topper adds an extra layer of plush softness without trapping heat. It stays cool throughout the night, which has made a noticeable difference for us as hot sleepers. The deep pockets fit our mattress securely, and it doesn't shift or bunch up. Since adding it, we've both been sleeping more comfortably and waking up feeling more rested. If you're looking to make your bed feel more luxurious while staying cool and comfortable, I highly recommend this mattress topper. It has exceeded our expectations and was absolutely worth the purchase!

All I can say is OMGAWD!!! Thank You~!~!! We got a new mattress after the previous "The Cloud" Serta pillow top (I'll never have another one) lasted for less than 8 years and I totally despised not being able to flip it models failed.. The new model is also a hybrid mattress, but is flippable and was just a bit too firm. I was feeling progressively more and more uncomfortable as the nights wore on, and with my serious back problems.. this just wouldn't do.. So I began searching "Our Beloved Amazon - heh" for an alternative, and after quite some time and research finally landed on this wonderful topper. It's like sleeping on top of well stuffed Ida Down on top of piles of silk. So very comfortable and my back pain is virtually completely gone now -such a relief! Be sure you follow the instructions on care and initial setup. You Do have to let it fluff out because of the vacuum packing (it wasn't really heavy btw). Mine decompacted fine, but I still want to run it through the dryer when we next venture to the laundromat. Shake it a little here and there when you take it out and at least let it sit for a few hours. It was just as easy to put on the bed as a regular mattress protector, and I also put my regular protector on top of it for added security and waterproofing. The materials feel like they are of good quality.. Viscose is also called Rayon and can be made from a number of different materials, so take good care of it and follow the washing instructions carefully. Delicate only, and cool only, and use only a horizontal washer that does not have a central agitator or you will tear it up. Only dry on low temperatures (preferably in a very larger laundromat dryer so it has plenty of room to loosely toss about. Drying it in the sun is alright as well, but it won't fluff like you want it to. I recommend using a waterproof and bug proof protector on top of this just to be sure you take care of it properly. Now I want to buy one for both my Mother and my Aunt HAHAHHA! TG it is in my price range.. barely. (Addendum: I have run it through the big dryer at the laundromat.. The dryer was cold so I gave it a quick warm on medium for anout 2 minutes and then tumbled on low for quite some time. The topper was fully ready in about 25 minutes, but I decided to elt it go on low while I did the rest of my laundry. It did perfectly and is just like the manufacturer photos.. I was so tired when I arrived home that I just flaked out on top of everything.. It was so comfortable that I was out liek a light in very short order and slept beautifully. I can attest that if you use this below your sheets instead of covering it with an additional mattress protector, that it does have better cooling effect. I will of course keep my waterproof/bugproof protector on top just for safety. The cat is nutz about the new topper as well.) Namaste.

I have to say, I’m genuinely impressed with this mattress pad. I wasn’t expecting much because it was so inexpensive, but this just goes to show that a higher price tag doesn’t always mean a better product. 3 months ago, I bought a $450 mattress pad from a high-end retailer, and within 2 weeks I returned it because it was uncomfortable and trapped heat. When I saw this one on Prime Day deals for only $35 and good reviews, I figured I had nothing to lose. If it was terrible, I’d just toss it. I’m so glad I took a chance. It isn’t super thick, so if you’re looking for something you can really sink into, this may not be the one for you. Personally, I like that it isn’t overly bulky. It’s incredibly soft and plush with a light, cloud-like feel, and my sheets still fit over it. It definitely has that “I don’t wanna get out of bed” vibe. It’s also surprisingly great at dispersing heat. I’m a very hot sleeper and I’ll usually wake up sweaty whenever the heat gets trapped underneath me. Since I put this on my bed, I haven’t woken up sweaty at all. I don’t know how it does it because it’s not really “cool to the touch,” but Bamboo is a naturally cooling material, so I guess that’s how it keeps the heat from building up. I have bamboo sheets and I absolutely love them. I’m very picky when it comes to my bedding, so I’m honestly shocked that this $35 mattress pad is the one I ended up loving. I would absolutely recommend giving it a try. The only reason I’m giving it four stars instead of five is because I’ve only had it for two weeks, so I can’t speak to how well it holds up over time. So far, though, I’m extremely happy with it.

YES!!!!!! I absolutely love this mattress topper! Before using it for the first time, I put it in the dryer to fluff it up, and it made all the difference. It became incredibly plush while still providing the perfect amount of support. It honestly feels like sleeping on a soft pillow, but with enough firmness to keep you comfortable all night. This is actually the second Niagara Sleep Solution mattress topper I've purchased because I upgraded to a larger mattress. I didn't even consider another brand because the first one was so amazing. If you're looking for a luxurious, hotel-quality sleep experience that stays comfortable and cozy, I highly recommend this topper. It's well worth it!

This topper was on sale and had free returns so I decided to give it a try. My mattress is on the firm side and I've been looking for a topper that would provide support along with softness without that sinking feeling that happens with foam. This is it!!! The fill in the topper is distributed just right, there's no bunching. It is not hot. So very comfortable.

This pad is the best mattress pad I’ve ever slept on. It gives a firm mattress just the right amount of softness to look forward to bed time. The pad kind of cuddles you a bit, but never do I get hot. The sheets don’t slip or bunch on this pad either, which is a big bonus for me.

I was getting worried reading the one star reviews after I bought it. Last night was the first night that I slept on it. It was honestly the best night's sleep I have had in a long time. It is definitely the way it is described. I have a disability and this helped so much with pressure points, aches and pains, it does have support to it. I will be honest, it is very fluffy and soft, but your not going to sink into it, if that's what you're looking for then this isn't for you. This makes it feel like your mattress has a pillow top on it. It is VERY comfortable and supportive. Please make sure you follow the directions and let it fluff up. The directions say you can put it in the dryer on low heat for 20 minutes to help it fluff, which was super easy! The reason I am giving this 4 stars instead of five is because it says it's cooling (and it is, to the touch) but it is not going to make you feel like it's been in the freezer, it's more of distributing your heat evenly, I was warm but like a comfortable warm. If you're looking for something that feels like the freezer, this probably won't be the one for you. It was very breathable as well. The size was kind of snug for our queen size bed, but it definitely fit, and still worked perfectly fine, especially when you get your fitted sheet on top of it. Other than that, this topper is excellent!
