Serta Power Chill Cooling Waterproof Mattress Protector — King, Cool-Hex Cooling & Waterproof, Fits to 15"

The Serta Power Chill Cooling Waterproof Mattress Protector (King) is a cool-to-touch, waterproof mattress cover that uses Cool-Hex fabric and breathable TPU lamination to keep your mattress cooler, cleaner, and protected from spills.

Combine cooling comfort with reliable mattress protection: this King-size Serta protector blends a glacier-knit top made of 90% nylon and 10% spandex with Cool-Hex technology, a breathable TPU barrier, and a soft polyester backing. It’s designed to resist stains and odors, fit mattresses up to 15" deep, and be machine washable for straightforward care. The result is a sleep surface that preserves your mattress while helping manage surface heat for a more comfortable night.

How does the Power Chill protector reduce surface heat?

The protector’s Cool-Hex technology and cool-to-touch glacier knit draw and dissipate surface warmth so you feel less trapped heat while lying down. The knit combines nylon and spandex for stretch and breathability, while the TPU lamination remains thin enough to allow airflow.

• Cool-Hex knit top (90% nylon, 10% spandex) for a cool feel
• 25gsm breathable TPU lamination to manage moisture and airflow
• Thin, flexible barrier layer to minimize heat retention

Will this protector keep liquids and stains away from my mattress?

Yes — the protector includes a waterproof TPU barrier that prevents spills and accidents from reaching the mattress core. Additionally, stain- and odor-resistant treatment helps reduce lingering smells and simplifies cleaning.

• Waterproof barrier stops liquids from penetrating the mattress
• 3M Scotchgard treatment resists stains and inhibits odor-causing growth
• Machine washable for stain removal and routine maintenance

Does it stay secure on deep mattresses and different mattress types?

The Serta Power Chill features an extra-wide elastic skirt that wraps around the mattress to keep the protector snug without shifting. It fits standard innersprings, foam, and hybrid mattresses up to 15" deep, making it versatile for most modern beds.

• Deep-pocket elastic skirt fits mattresses up to 15" deep
• Full-coverage design prevents slipping and bunching during sleep
• King size measures approximately 78" x 80" for wide compatibility

How should I care for and clean the mattress protector?

Care is simple: machine wash cold on a gentle cycle and tumble dry low to maintain the fabric and waterproof layer. Avoid chlorine bleach, ironing, and dry cleaning to preserve the Cool-Hex knit and the TPU membrane.

• Machine wash cold, gentle cycle with like colors
• Use non-chlorine bleach only when necessary; tumble dry low
• Do not iron or dry clean to protect materials and coatings

Who is this for? The Serta Power Chill Cooling Waterproof Mattress Protector (King) is well suited for sleepers who want a cooler sleep surface without sacrificing waterproof protection. It fits those with deep mattresses, parents and pet owners seeking spill protection, and anyone looking to extend mattress life with a breathable, easy-care cover from an established bedding brand.
