What to Consider When Choosing the Best Pillow Protector 

Selecting the best pillow protector depends on a few factors, including price, type, and size. Also consider fabric: For allergy sufferers, hypoallergenic or antimicrobial pillow protectors may be the best solution. Before making a decision, learn about the properties of each type of fabric and decide if you need a cooling or breathable fabric. Design, color, and patterns also may influence the decision.

Pillow Type

Pillows are available to suit three basic sleeping positions. Those who usually sleep on their back or stomach may prefer thinner pillows with less loft (height), which are designed to align the neck with the spine. On the other hand, side sleepers may want a thicker pillow with higher loft to hold their head in a balanced position.

In addition to loft, pillows vary according to their filling. For those allergic to down, polyester fiberfill may be an option. Memory foam, a more expensive filling, doesn’t clump like polyester fiberfill but may emit a chemical odor when new. Natural down-feather pillows are soft, lightweight, and easy to shape, but the feathers can cause allergic reactions in some sleepers.


Bed pillows are available in three sizes: standard, which measures 20 by 26 inches; queen, at 20 by 30 inches; and king, which measures 20 by 36 inches. Manufacturers produce pillow protectors in all three sizes.


Pillow protectors are available in a variety of fabric choices as well.

  • Organic cotton, soft, durable, and breathable, is grown without the use of pesticides or synthetic fertilizers.
  • All-natural, 100 percent cotton is soft, breathable, and comfortable, and it can help regulate temperature.
  • Special cooling fibers make pillow protectors feel cool to the touch and offer a solution for hot sleepers.
  • Polyester microfiber fabric is soft and smooth, but it may not be as breathable as 100 percent cotton.
  • Some fabrics are treated with an antimicrobial finish to inhibit the growth of bacteria and buildup of allergens.
  • Hypoallergenic fabrics have an extra-small weave to block particles such as dust mites, pet dander, pollen, and bed bugs.
  • Waterproof pillow protectors incorporate an impermeable membrane into the fabric.

Thread Count

Thread count refers to the number of threads in a square inch of fabric. A higher thread count usually indicates higher-quality fabric with extra softness and durability. Thread count, however, isn’t always a reliable indicator of quality. For example, fabric made with a low-quality thin cotton thread results in a high number of threads per square inch, but not better quality.

Zipper vs. Slip Case

To protect pillows from moisture, sweat, dirt, dust, and tiny particles that may cause an allergic reaction, pillow protectors work best when they completely enclose the pillow.

  • Most pillow protectors feature a zipper on one end to fully encase the pillow and seal off outside elements.
  • Other pillow protectors feature a slip case design, which means they’re open on one end to make them easy to remove.

Colors and Patterns

Many manufacturers offer their pillow protectors in only one color option—solid white—which allows the user to choose a pillowcase in any color or pattern. However, colored protectors are available.
