National Allergy 100% Cotton Twin Mattress Encasement 39x75x9, Hypoallergenic, Dust Proof Zippered 6-Sided Cover, Breathable, Noiseless Natural Cotton, AAFA Certified

Got this a few weeks ago after first trying the Allersoft pillow cover made from the same material. I have a dust mite allergy and was constantly suffering with a very stuffy nose all night long. OTC medication (Zyrtec) did not help it. The only thing that helped was prescription Flonase. But after using it 2+ years, my nasal cavities became irritated. So I tried this mattress cover, and switched to Allegra OTC. My allergy symptoms are much better. Not 100% gone, but 80-90%. I only have occasional stuffy nose while sleeping now, and suspect it is due to dust mites in the room (carpet) and not from the mattress. My next step will be to eliminate the carpet and go to hardwood floors. Oh, I also use an Eco Living Friendly (ELF) box spring protector purchased from Amazon. I can't say for sure that either the mattress covers or the Allegra have provided the biggest benefit. But the cost for the mattress cover is only equal to a few months of allergy medication, so it is money well spent if it adds another layer of control. I can say that there have been no negative effects from the mattress cover. The best thing about it is it is very soft and cool. It was easy to put on a regular twin. All I did was raise up the mattress from the foot of the bed until it was vertical. Then slid the cover over the top (head) and pulled it down to the bottom. Then laid the mattress head back down, lifted the mattress foot slightly, and pulled the cover over the foot of the mattress and zipped it up. It fits quite loose on my regular 7" deep mattress, so I just tucked the extra material underneath. For anything larger than a regular twin, this is probably a 2 person job to put on.

These were easy to install onto my mattress although when zipping it up I had to be extra careful as it reluctantly zipped but I won’t be taking it off again for what I hope will be at least a couple years so that was not much of a problem. There’s not much noise to be heard when you lay on it, I just hear my sheets whispering which isn’t near as loud as my previous mattress cover was so I’m very pleased with this one. It had a bit of that new smell but it’s already gone a few days later too.

Exactly what I wanted! No heavy plastic backing so it's super breathable and quiet. I keep forgetting it's even on the mattress. I ordered a size up for the depth of bed I have. I just tucked the extra material under the mattress.

I can't believe I wasted $75 on this thing, I could have made a better one myself with a couple of bedsheets. Where to start? First I washed it because it smelled chemically when I opened the package. Putting it on was a pain, I had to shift my mattress onto the end and shimmy this down side to side, it barely squeezed on and busted a seam on one side of the zipper. When I finally got it on, the zipper foot came off because there's no stopper to prevent that, so I had to re-atrach it, then hand sew up the end of the zipper and the few inches where the seam broke. It was so tight that it ruined the plush feel of my euro top, I feel like I'm sleeping on a tightly pulled cot. Now if I want to take it off, I'm out $75 and a ton of effort for what's essentially a couple of thin sheets sewn together with too long of a stitch with a low quality zipper, and no velcro to properly seal the zipper opening. If I ever wanted to wash it again, the whole point of a washable mattress cover, it would be in shreds just taking it off and back on again.

Good quality at an acceptable price. Item is well packed and at good condition. Comfortable mattress and the size fits as what the description says. It takes time to see if it really works to prevent allergy.

Highly recommend these for dust mite allergy! My partner would wake up every morning with a sinus headache so we decided to try this. We first tried a few cheaper plastic based alternatives but they made the bed so hot. This one though slips on and you don't even realize it's there. Her headaches have completely disappeared. Definitely buy the matching pillow cases as well.

I bought this waterproof mattress protector with zipper and it has been an excellent purchase. It fits perfectly to the mattress and covers it completely, which provides great protection against spills, sweat, dust and mites. The material feels soft to the touch and makes no noise when moving during the night, something that worried me at first.

This allergy-proof, dust-proof mattress cover has been a total lifesaver for me! I'm severely allergic to dust mites, get styes and bad eye allergies, and I also have cats, so keeping my bed allergen-free has always been a challenge. Since using this cover, my nights have been so much more comfortable, and my allergies are finally under control. The cover fits my mattress perfectly, creating a snug, impenetrable barrier. The material feels durable yet soft and breathable—| was worried it might feel plasticky or noisy, but it doesn't at all. It's also super easy to clean, which is a must with cats around. What I love most is that it doesn't just keep out dust mites; it also keeps cat hair and dander from settling into my mattress. Now I can cuddle with my cats without worrying about allergens building up where I sleep. If you're someone with allergies and pets, this is an ansolute must-have. My quality of sleep and overall comfort have improved so much, and I couldn't be happier with this purchase!
