The word “hypoallergenic” can make bedding sound more certain than it is. It does not guarantee that a product will prevent symptoms. For a practical buying decision, look at the actual construction: how tightly the fabric is woven, whether it fully zips around the item, how it fits, and whether you can wash it as directed.
This list focuses on mattress and pillow encasements rather than comforters, sheets, or decorative covers. If you are comparing fills instead, the guides to duvets and allergies and down-alternative bedding for allergies cover a different part of the bed.
The four options below include two mattress encasements and two pillow protectors. None should replace personal medical guidance. Their useful differences are material, coverage, zipper design, depth, feel, and laundry care.

Our Four Picks
1 / 4
National Allergy Cotton Mattress Encasement
Material
Cotton
Size
Queen, 60 x 80 in
Depth
6 to 9 in
Coverage
Six-sided zipper encasement
This National Allergy encasement surrounds all six sides of a Queen mattress. The selected size is made for a 60-by-80-inch mattress from 6 to 9 inches deep. Its cotton fabric is listed with a tight 2.6-micron weave, and the zipper has an auto-lock slider plus an internal fabric flap. There is no laminated waterproof membrane.
Relevant owners often describe the fabric as soft, light, quiet, and more natural-feeling than plastic-backed covers. Fit and installation deserve care: some people find the zipper easy to use, while others report size problems or need a second person to lift the mattress. Measure the depth before ordering and do not expect this shallow variant to stretch over a thick pillow-top bed.
Why It Works
- Cotton gives shoppers an alternative to synthetic microfiber.
- Six-sided coverage encloses more than a fitted protector.
- The membrane-free design avoids a plastic-backed feel.
What To Keep In Mind
- The selected Queen variant fits only 6- to 9-inch mattresses.
- Installation may require help because the mattress must be lifted.
- It is not presented here as a waterproof protector.

Mission Allergy Premium Microfiber Mattress Encasement
Material
100% polyester microfiber
Size
Queen, 60 x 80 in
Depth
12 in
Closure
Extra-long zipper with inner flap
The Mission Allergy Premium encasement uses tightly woven polyester microfiber rather than cotton or a coated waterproof layer. The chosen Queen size measures 60 by 80 inches with a 12-inch depth. Its listing specifies a 2-micron mean pore size, bound seams, an interior zipper flap, and an extra-long opening that extends around much of the mattress.
Owners commonly mention a smooth, quiet feel and an opening that makes installation easier than covers with a short end zipper. Some have put it on a heavy mattress alone, though lifting any large mattress can still be awkward. The fabric is described as water repellent, which is not the same as waterproof; choose a separate supported barrier if liquid protection is required.
Why It Works
- The long zipper creates a wider opening for installation.
- Bound seams and an inner zipper flap address common closure gaps.
- Lightweight microfiber feels less bulky under a fitted sheet.
What To Keep In Mind
- Confirm that the 12-inch depth matches the full mattress profile.
- Water-repellent fabric should not be treated as waterproof.
- Avoid expecting a specific health result from the product label.
3 / 4
Mission Allergy Barrier II Pillow Encasement
Material
100% polyester microfiber
Size
Standard
Closure
Zipper with two fabric flaps
Care feature
Washable construction
Barrier II is a single Standard-size pillow encasement made from woven polyester microfiber. Its listing specifies a 6-micron mean pore size, bound edges, and both interior and exterior zipper flaps. The outer flap also keeps the zipper hardware from sitting directly against the sleeper's regular pillowcase.
Product-specific feedback often highlights the quality of the zipper, a comfortable fabric feel, and good results after washing. Fit comments vary by pillow size, so check the dimensions rather than assuming that every Standard or Queen pillow has the same loft. This is an encasement that goes under a normal pillowcase, not a decorative case or padded pillow shell.
For the rest of the bed, follow a practical bedding-washing routine that does not overload the machine.
Why It Works
- A full zipper encloses the pillow rather than covering one face.
- Inner and outer flaps add fabric around the zipper area.
- The smooth microfiber stays under a regular pillowcase.
What To Keep In Mind
- The selected product is a single Standard-size encasement.
- A thick or overfilled pillow may need a larger size.
- Do not rely on unrelated waterproof or pest-control reviews.

AllerEase Standard/Queen Pillow Protectors
Material
88% polyester, 12% nylon
Size
Standard/Queen
Quantity
2
Care
Machine wash warm, tumble dry low
This AllerEase package contains two zippered Standard/Queen pillow protectors. The fabric is listed as 88% polyester and 12% nylon. It is designed as a soft, breathable layer that fully covers each pillow, and the care directions allow a warm machine wash followed by low tumble drying.
Owners often say the covers feel quiet, fit fluffy pillows without changing their shape too much, and wash without obvious shrinking. The main weak point is zipper consistency: several buyers like the easy closure, while a smaller group reports a broken or rough zipper. The listing does not support using these as waterproof covers, so keep that job separate.
Why It Works
- The two-pack covers a common pair of bed pillows.
- Zippered construction encloses more than an open pillowcase.
- The fabric and care routine suit regular bedding laundry.
What To Keep In Mind
- Inspect both zippers before placing the protectors on the bed.
- Standard/Queen sizing may be loose on a small pillow or tight on a very full one.
- These protectors are not a supported waterproof solution.
How to Choose Hypoallergenic Bedding Protection
Choose full coverage when that is the goal
A fitted mattress protector covers the top and sides like a fitted sheet. A six-sided encasement closes around the whole mattress. The mattress encasement roundup compares more full-cover options, while the guide to choosing a mattress encasement explains depth, zipper, and installation details.
For pillows, compare the best pillow protectors and review what to look for in a pillow protector. A protector should fit without crushing the pillow or leaving so much extra fabric that it bunches under the pillowcase.
Read beyond the label
“Hypoallergenic” is a broad product term, not a promise that no one will react. Look for specific, useful facts: fiber content, construction, pore-size claims when supplied, zipper coverage, seams, membrane layers, mattress depth, and wash directions. Avoid treating a waterproof claim, pest claim, or customer health story as proof of a guaranteed outcome.
Plan installation and washing
Wash only as the product directs. The guide to washing an encasement before first use can help with setup, while the advice on machine-washing pillow protectors covers the smaller pieces.
Frequently Asked Questions
What does hypoallergenic bedding mean?
It generally means the product is designed to reduce common irritation concerns or limit places where particles collect. The term does not guarantee that a person will have no reaction, so check the construction and materials.
Is a mattress encasement the same as a mattress protector?
Not always. An encasement closes around all six sides with a zipper. A fitted protector usually covers the top and sides but leaves the bottom open.
Is cotton or microfiber better for a mattress encasement?
Cotton may feel more natural and familiar. Microfiber can be smoother, lighter, and easier to slide over a mattress. Fit, weave, zipper design, and care matter as much as the fiber name.
Should pillows also have zippered protectors?
They are useful when you want a washable layer that fully encloses the pillow. Put a regular pillowcase over the protector for everyday comfort and easier laundry.
Does hypoallergenic bedding need to be waterproof?
No. Particle-barrier construction and liquid protection are different jobs. Some waterproof membranes also change the feel, noise, or breathability of bedding.
How often should encasements and protectors be washed?
Follow the manufacturer’s care schedule and wash sooner after spills or visible soil. Washing too hot or drying incorrectly can damage fabric, elastic, or barrier layers.
How do I choose the correct encasement depth?
Measure from the bottom seam to the highest point of the mattress. Include any layer that will remain inside the encasement, then choose the listed depth that matches that total.
