Give your mattress natural, breathable allergy protection with the Bargoose AllergyCare® Cotton Zippered Mattress Encasement. Made from the same 100% cotton allergen-barrier fabric as our AllergyCare® pillow protectors, this fully zippered encasement seals the entire mattress in soft, breathable cotton that helps block dust mites without plastic film, crinkle, or trapped heat.

Why 100% cotton? Most dust-mite mattress covers use a laminated membrane or plastic backing that feels stiff and sleeps hot. AllergyCare® blocks allergens through the tight weave of the cotton itself, so you get a proven barrier with the natural softness and airflow of pure cotton, and nothing laminated to the fabric.

Key features

  • Dust mite barrier: Tightly woven 100% cotton helps block dust mites and their allergens from the mattress.
  • Quiet and breathable: No plastic film or crinkle, and no added heat retention.
  • Complete 360° encasement: Fully zippered on all sides to seal the entire mattress.
  • Durable closure: Heavy-gauge nylon zipper with reinforced seams.
  • Custom fit: Multiple mattress sizes and depths for a snug fit.
  • Machine washable cotton construction.

Independent pore-size testing

This encasement uses the same 100% cotton fabric independently analyzed by Porous Measurement Int'l Group (August 2025), which measured a mean flow pore diameter of 4.62 microns. That tight weave forms the physical barrier that helps block dust mite particles while keeping the cotton breathable. View the pore size analysis report (PDF).

Specifications

  • Type: Zippered cotton mattress encasement (allergen barrier)
  • Material: 100% cotton
  • Mean pore size: 4.62 microns (independently tested)
  • Construction: Tightly woven cotton, no coatings or laminates
  • Closure: Heavy-gauge nylon zipper, 360° encasement, reinforced seams
  • Protection: Dust mites and dust mite allergens

  • Pack: Sold individually (one encasement)

Sizes and depths

Available in Twin, Full, Queen, and King, with mattress depths of 9", 12", 16", and 18" for a custom fit. Measure your mattress height and choose the matching depth.

Who it's for

Ideal for allergy and asthma sufferers who prefer a natural cotton encasement over synthetic, laminated, or plastic protectors, and for hotels, healthcare, and institutional programs that want a breathable, launderable cotton barrier.

Care and cleaning

  • Machine wash warm; tumble dry low
  • Do not bleach
  • Wash before first use to set the fit

Complete the protection

Frequently asked questions

Is it dust mite proof?
The tightly woven 100% cotton creates a physical barrier that helps block dust mites and their allergens, verified at a 4.62-micron mean pore size.

Is it waterproof?
No. This encasement is breathable cotton with no membrane, so it is not waterproof. For spill and moisture protection, see our waterproof protectors and encasements.

Which depth should I choose?
Measure the height of your mattress and pick the closest depth: 9", 12", 16", or 18".

Is it machine washable?
Yes. Machine wash warm and tumble dry low. Wash it before first use to set the fit.

Very nice cotton

Very nice cotton. It is nice to have this encashment for my boxsprings.
Laundered very well. I love that it is OEXO certified foe such a reasonable price.
Love that the weave is so tight that no dust mites can go in or come out of the encashment!

Hi there! So glad you're happy with it! 😊 The soft cotton, tight weave, and OEKO-TEX certification are some of our favorite features too. Thanks for sharing your experience!

Helped with Allergies, but completely unusable

I purchased a queen cotton mattress encasing and 4 pillowcases. It absolutely helped with my allergies, but I ultimately had to remove them from my bed because they made me so hot and sweaty! I am not usually a hot sleeper but this product made me so hot and uncomfortable that it actually woke me up out of deep sleep in the middle of the night. It felt like the heat was building up directly under me so I had to constantly toss and turn. I am unable to return it because it is is out of its original packaging. This was a costly mistake and now I am stuck with expensive sheets that I can't use. I absolutely do not recommend this product!

Seems great

I don't have allergies but I bought as a precaution. So I can't say it works but it's made well and now I have them on the guest mattresss as well as mine.

Thanks for your review! We're glad to hear you're happy with the quality and construction of the encasements. 😊

Good purchase

Tightly woven soft cotton. Good zipper quality. It doesn't make mattress or pillows hot or noisy. Much better than synthetic materials.

No detergent smell

If your allergies are due to MCS, like mine, you know how awful it is to buy something ostensibly for people with allergies only to find it unusable because it was washed in smelly laundry detergent. That smell is toxic chemicals! This mattress cover does not cause reactions for me and hopefully not for anyone else.

Hi Lona,

Thank you for your comments. We are glad to hear the mattress protector is working well for you. Please let us know if there is anything else we can do for you.

Haven't bought anything from an allergy site before, but my allergy doctor said to make some changes. I just put the mattress and pillow encasements on the bed, and so far, so good! I have saved your site and may purchase more in the future!

Great Products

We bought the cotton mattress encasings in the long twin size (we have an adjustable bed which has two xl twins), as well as the pillow covers. The mattress covers were a bit large, but not a problem. These are well made products and help with my allergy to dust mites. Would recommend these great products.

Good morning Mollie,

We just wanted to follow up and see how it is going with you new mattress covers. Please let us know if there is anything else we can do.

Thanks,
Mike

Great cover

This is the second of these covers that I’ve ordered after being impressed with the quality of the 1st one. They fit very well over my deep mattresses. Would recommend.

Noisy

I will not be using this. It is too loud and crinkly when you toss/turn. In addition, the size I purchased, which should have fit my mattress, is way oversized. Will it form a barrier? I’m sure it will, but other things matter to me, too.

We bought one of these a few years ago for our mattress when my husband was having allergy issues with dust mites. Now our daughter is also allergic to dust mites and we thought we should try this again. So at the same time she was getting a new mattress we got her this mattress cover and it really does help. Thanks for a great product. *Verified purchase, originally submitted on the AllergyStore storefront.

Quality of material was excellent. However I measured per the instructions on the website prior to ordering. The item received was much too large for my mattress Despite following those specific measuring instructions. Had to return the product which was not the easiest process. *Verified purchase, originally submitted on the AllergyStore storefront.

Years ago I bought a cover from this company and immediately stopped itching every night when I went to bed. We recently bought a new bed. The mattress was a little thicker so we needed a new mattress protector. My big problem is dust mites. So I bought a new cover to protect our new mattress and also covers for the boxsprings. I spent years just itching when I went to bed and not understanding why. It’s such a pleasure to go to sleep. *Verified purchase, originally submitted on the AllergyStore storefront.

I looked at several different mattress covers before purchasing this queen size allergy care cotton mattress encasing from the Allergy Store and I'm happy to say I'm very pleased with it. I noticed right away that I was sneezing less when in my bed. The fabric is tightly woven but not noisy. It fit perfectly over my pillow top mattress and best of all I got the encasement on the mattress without much trouble. I don't know why some of the Reviewers complained about it being difficult to get on and saying it is a two person job I'm an 80-year-old woman and I did it by myself. *Verified purchase, originally submitted on the AllergyStore storefront.
