Niagara Sleep Solution Side-Shield Waterproof Mattress Protector King — 6-21 in Deep Pocket

Protect your king mattress with a protector designed to combine edge-to-edge defense with soft, cooling comfort. The Niagara Sleep Solution Side-Shield Waterproof Mattress Protector uses a breathable bamboo-viscose surface and a waterproof core to help keep nighttime spills and stains at bay without sacrificing sleep quality.

Edge-to-edge protection you can feel

The standout feature is the 4-inch side shields. These extended panels rise up the mattress sides, creating a barrier against spills, sweat, and accidents that often reach the edges. The result is a more confident setup for households with children, pets, or late-night snacks in bed.

• 4-inch side shields guard the most vulnerable edges
• Extended barrier works alongside the main fabric to block moisture
• Designed to fit a king with a 6-21 inch depth

Breathable, quiet, and cool

The fabric blends bamboo-derived viscose with a polyurethane backing. The surface stays smooth to the touch, offers a light cooling sensation, and supports airflow so you don't feel hot or damp while you sleep.

• Cooling pattern design for a more comfortable night
• Viscose bamboo is soft and breathable
• Polyurethane backing blocks liquids yet breathes

Simple, secure fit and care

The king protector features a deep pocket and extra-long stretchy sides for quick fitting on thick mattresses. It remains fluffy after machine washing, so you can refresh your setup without fuss.

• Deep pocket and stretchy sides for easy installation
• Machine washable; dries fluffy
• Noiseless layer minimizes rustling for a peaceful night

Real-world benefits and reassurance

Whether managing spills from kids, pet accidents, or sweaty nights, this protector provides a practical layer of defense that can help extend mattress life and preserve comfort. While experience varies, many users appreciate the cool, quiet feel and straightforward upkeep.

Niagara Sleep Solution stands behind its product with a satisfaction promise, offering a good value option for families seeking better sleep protection without compromising comfort.
