It is cotton, great zipper!
This cover is easy to use, has more than met my expectations. I am glad I ordered it. I am currently using it on my hospital bed with a mattress topper. Works great. Thanks, and it has decreased slipping of the additional mattress topper I have on top. This is what I was hoping for. Great value. Good fit. Washed up nicely. NO noise. I highely reccommend this cover.

My son uses this along with the Lucid Foam matress and he loves it. It is silky soft and eady to put on. It zips over his entire matress and foam matress togethet leaving eaverything tight and in place

Nice, soft material
Nice, soft material. Not plasticky or smelly. I have a natural latex mattress which I seem to have developed an allergy to. I was hoping that this would prevent me from itching at night, but it did not, so I returned it. After purchasing 3 different encasings, I finally found an encasing that does actually prevent me from itching without feeling hot and sweaty or plasticky: protect-a-bed.

I’m not sure I get what as advertised
They advertise “ Featuring a super-tight weave with a mean flow pore size diameter of 3.44 microns” on the website. This is the main reason I made this purchase. But I didn’t find any words on the sheet inside the package. I cannot believe they did this by negligence!

Dust mites aren't going anywhere
On the subject of reducing allergy symptoms, there isn't consistent evidence that dust-mite impenetrable barriers of any material reduce asthma or allergy symptoms over time. In the studies I've read they do reduce dust mite populations, but that doesn't make enough of a difference to affect allergic reactions in patients. Check out studies and reviews of the subject on PubMed to decide for yourself if that interests you. The review from the Cochrane Collaboration seems to be the most comprehensive (and contested). The Allersoft mattress coverings are well made, 100% cotton, and they wrinkle in the dryer, which (I hope) means no formaldehyde wrinkle-resistant coating. They'll keep your bedding clean, won't make your bed warmer, and are easily washed. I like them and I suggest them for those reasons, but I wouldn't expect any product of this kind to have a lasting effect on allergy symptoms.

no comlaints
Wasn't hard to put on twin extra long bed with help from 12 year old user. I think it might be harder to put on solo. No complaints from the 12 year old user nor parent.

Great product
Very happy with the difference in my dust mite allergies when using these mattress and pillow covers. They fit the mattress a bit loose, but not bad, just enough to make them easy to get on the mattress.

Zipper at Top, Impossible for Latext Mattress
This might work great if you have a regular mattress, but for my latex mattress, I couldn't get it on. You can't tip a latex mattress onto it's end like you can a spring mattress. But either way, why not put the zipper all the way around so you can lay it down, put the mattress on top and then zipper it closed? To me, this design cuts corners and there's no excuse. It's too bad because the fabric feels nice. There aren't too many covers that are plastic free. Bed wetting isn't an issue. This would have been perfect.
