Review: Soft, effective allergy control mattress cover - 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 desertcart. 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.
Review: Nice and easy - 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.

### ⭐⭐⭐⭐⭐ Breathable and quiet
*by M***L on December 30, 2025*

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.
