Niagara Sleep Solution Waterproof Pillow Protectors — 4-Pack King Size White, Zippered & Breathable

Niagara Waterproof Pillow Protectors are zippered, feather-proof pillow encasements that keep king-size pillows dry, clean, and comfortable while preserving breathability and sleep feel.

These Niagara Sleep Solution pillow protectors come as a value 4-pack in king size (20" x 36") and combine a soft jersey-knit surface with a 100% waterproof polyurethane membrane to block liquids, stains, sweat, and dust while staying quiet and breathable. The covers are designed with an auto-lock zipper that seals fully and prevents accidental opening, and they are machine-washable for easy care. Built to extend the usable life of pillows, these protectors fit standard bedding and deliver a near-original pillow feel thanks to the smooth polyester knit top.

How do these protectors keep pillows dry without feeling plastic?

Niagara protectors use a microscopic-pored polyurethane membrane laminated beneath a jersey-knit polyester top. That membrane stops all liquids from passing through while microscopic pores allow vapor to move, preventing the clammy plastic sensation common with cheap covers.

• 100% waterproof polyurethane barrier for liquid protection
• Jersey-knit polyester surface for a soft, fabric-like touch
• Microporous membrane allows breathability and moisture vapor transfer
• Quiet construction that minimizes crinkling and noise during sleep

Will these pillow covers fit my king pillows and stay closed overnight?

Yes — the set includes four king-size pillow protectors (20" x 36") that fully encase a standard king pillow. Each cover is finished with a premium auto-lock zipper that seals the opening and prevents accidental unzipping during use or while laundering.

• King size dimensions 20" x 36" per protector
• Durable, auto-lock zipper prevents accidental opening
• Full zipper closure encloses the pillow for complete protection
• Careful stitching and reinforced seams for everyday use

How do I care for the Niagara Waterproof Pillow Protectors?

These covers are made for regular home laundering: machine wash with mild detergent and tumble dry low or line dry. The materials are chosen to retain the waterproof membrane performance after repeated washing, making maintenance simple and cost-effective.

• Machine washable with mild detergent
• Tumble dry low or line dry to preserve membrane longevity
• Avoid bleach and high-heat settings to protect the zipper and membrane
• Wash before first use to ensure fresh feel and hygiene

What problems do these protectors solve for pillow owners?

They protect pillows from spills, sweat, drool, allergens, and dust mites while maintaining comfort and appearance. Replacing stained or damp pillows is costly; these protectors add years of usable life to pillows and simplify mattress and pillow care routines.

• Prevents liquid damage, stains, and odor buildup
• Guards against feather escape and pillow wear
• Makes pillows easier to keep hygienic and allergen-controlled
• Cost-effective 4-pack replaces frequent pillow purchases
