Allersoft Square Cotton Dust Mite and Allergy Control Pillow Protector, 20 by 20-Inch

We use feather pillows and these covers are great in cutting cost of laundering. They keep in the feathers, preserve the pillows and I love that the zippers on these cases are well made.

Throw pillow protectors are hard to find. 100% cotton throw pillow protectors are nigh impossible. We need them to keep the down feathers from poking through and more importantly to alleviate allergies and asthma triggers. We use these National Allergy Premium 100% Cotton encasements on all our bed pillows, mattresses and comforters. They’re brilliant. These are NOT INTENDED TO BE WATERPROOF. The tight weave will actually give you some stain protection and extra time to grab a towel if someone spills, but they are not intended to keep pillows dry. Pure cotton, smooth, crisp, work flawlessly for our allergen purposes. Workmanship and zippers are quality. I buy one size smaller than my throw pillow for hotel-like plumpness (20x20 protector on 22x22 down pillow and 20x20 case). But you may want to buy the actual matching size if your insert is very firm or very full. Tips: I always wash before use to soften and remove any smells or dust from manufacturing. To avoid shrinkage and wrinkles — wash in warm on delicate, dry on low temp and take out ever so slightly damp, smooth with your hands, and finish drying on a rack (or over a chair). They wash beautifully like this, no ironing. Yes, they are definitely more expensive than the 100% polyester, polyurethane-lined versions. But they last forever with reasonable care (don’t overstuff or yank on the zippers 😊). And your pillows won’t shrinkwrap into pancakes, fill up like balloons, crinkle like plastic grocery bags or fire up like heating pads under your head. Try both types (like I have) — unless you need water resistance, betting you’ll choose the all-cotton.

Bought these to keep feathers inside of a throw pillow on our couch. Works great! Have had this for months now and no more feathers. Sizing data is accurate fit my pillows perfectly.

These pillow protectors seem are exactly what I was looking for. They fit my 20" x 20" pillow inserts perfectly. I love that they protect by making a tight weave with the cotton rather than using chemicals. The tag says "Made in U.S.A." and "100% Cotton" and "Machine Wash Warm. Tumble Dry Low." My only complaint is that if you turn it inside out and look at the ends of the seams, they didn't tie off the thread. I hope the company reads this and does a better job so they help make "Made in U.S.A." keep meaning something positive.

I bought these to prevent feathers from shedding from my throw pillows. They are working like a charm. No more feathers all over the couch.
