SureGuard Pillow Protectors Set of 2 King 21 x 37 – 100% Waterproof, Hypoallergenic Zippered Cotton

These SureGuard king-size pillow protectors are zippered cotton covers that offer waterproof, bed-bug-proof and hypoallergenic protection while keeping your pillow soft and quiet.

Keep pillows cleaner and longer with a set of two SureGuard king pillow protectors sized 21" x 37". Made with a smooth 100% cotton exterior and a fully sealed zipper, these covers block liquids, dust mites, mold spores, pollen and pet dander without the crinkly feel of vinyl. Independently lab tested and GREENGUARD Gold certified, the protectors are machine washable and backed by a 10-year quality guarantee.

How do these protectors defend against spills and stains?

The interior membrane creates a complete barrier that stops perspiration, saliva and accidental liquid from passing into the pillow fill. Because the cotton surface is impermeable underneath, liquids bead and wipe off instead of soaking through.

• 100% waterproof internal layer prevents liquid transfer
• Machine-washable construction for easy cleanup
• 10-year quality guarantee for long-term reliability

Can these covers keep out bed bugs and allergens?

Yes — a super-fine, fully enclosed zipper uses Invisi-Zip technology to close off every seam, limiting access for bed bugs and microscopic allergens. The tightly woven barrier also blocks dust mites, pollen, mold and pet dander to help maintain a cleaner sleep surface.

• Bed bug–proof zipper seals the pillow completely
• Hypoallergenic fabric limits dust mites and pollen entry
• Works well with SureGuard mattress and box spring encasements

Will the protector change how the pillow feels or sound?

The outer layer is smooth 100% cotton designed to keep the pillow’s natural softness and breathability. The inner barrier is engineered to be quiet, avoiding the crinkly noise typical of vinyl or PVC alternatives.

• Soft cotton surface retains pillow comfort
• No vinyl, PVC, phthalates, or fire-retardant chemicals
• Stops feathers and quills from poking through for down pillows

How do I care for and size these pillow covers?

Each cover fits standard king dimensions (21" x 37") and is simple to maintain: zip closed, machine wash, and tumble dry. The durable stitching and zipper are tested for long-term use so the protector holds up through repeated cleaning cycles.

• Fits king pillows 21" x 37"; set includes two covers
• Machine wash and tumble dry safe for convenience
• Durable zipper and seams withstand regular laundering

Who this is for: sleepers who want to preserve pillows from spills, allergens and pests while keeping the original feel—especially owners of down or feather pillows, allergy-prone individuals, pet households, or anyone seeking GREENGUARD Gold–certified bedding protection. Choose these SureGuard zippered cotton protectors when you want quiet, breathable defense without sacrificing comfort.
