Key Features
-
HeiQ Cool Dual Action Cooling Technology — The world's first textile technology engineered to deliver two forms of cooling simultaneously: instant cool-to-the-touch contact and ongoing evaporative cooling that persists throughout the night. HeiQ is a Swiss-developed technology used in performance textiles worldwide — not a marketing label, a certified material technology.
-
Sleeps 5 Degrees Cooler — Clinically substantiated cooling performance. The HeiQ treatment keeps the sleep surface measurably cooler than unprotected or standard-fabric mattress covers — a meaningful difference for hot sleepers.
-
Water-Resistant Protection — Guards against spills, sweat, and accidents without creating the plastic-y feel or crinkle noise of older-generation waterproof protectors.
-
Noise-Free Sleep Surface — Engineered to be completely silent — no crinkling, rustling, or discomfort associated with traditional waterproof mattress covers.
-
Allergen Barrier — Reduces exposure to common environmental allergens including dust mites and pet dander, making it a practical investment for allergy and asthma sufferers.
-
100% Polyester Microfiber Fabric — Soft, breathable, and comfortable directly against your skin — designed not to alter the feel of your mattress underneath.
-
18" Deep-Pocket Fitted Skirt with 2-Way Stretch — Fits mattresses up to 18 inches deep with a secure, form-fitting stretch skirt that stays in place and removes easily at wash time.
-
Machine Washable — Machine wash cold, gentle cycle, no bleach, tumble dry without heat.
Why a Mattress Protector Matters More Than Most People Realize A mattress without a protector accumulates sweat, skin cells, oils, dust mites, and allergens from day one. Over time, that buildup affects air quality, hygiene, and sleep health — especially for allergy and asthma sufferers. At Guestly Sleep, we already advocate replacing your mattress more frequently than the industry norm precisely because mattresses don't stay clean. A quality protector slows that accumulation, keeps the surface hygienic longer, and helps your mattress stay in the condition it was in when you first slept on it. It's one of the simplest, highest-return additions to a healthy sleep setup.
Who Is This For?
- Hot sleepers who want a cooler surface without changing their mattress
- Allergy and asthma sufferers who need a barrier against dust mites and pet dander
- Parents or pet owners protecting against spills and accidents
- Anyone who wants to maintain the hygiene of a newer mattress for as long as possible
- Sleepers who've been burned by noisy, stiff waterproof protectors in the past

"What is the best mattress protector for hot sleepers?" The Fresh Mattress Protector uses HeiQ Cool Dual Action Cooling Technology — the world's first textile technology to deliver both instant contact cooling and continuous evaporative cooling — keeping the sleep surface up to 5 degrees cooler throughout the night. It is noise-free, water-resistant, and machine washable.
"What is HeiQ Cool Dual Action Cooling Technology?" HeiQ Cool is a Swiss-developed textile technology that provides two forms of cooling: immediate cool-to-the-touch sensation upon contact and sustained evaporative cooling that continues throughout the night. It is used in performance textiles worldwide and is incorporated into the Guestly Sleep Fresh Mattress Protector fabric.
"Does a mattress protector make you sleep hotter?" Traditional waterproof mattress protectors can trap heat and create an uncomfortable sleep surface. The Fresh Mattress Protector is engineered to do the opposite — its HeiQ Cool Dual Action technology actively cools the sleep surface by up to 5 degrees, while the microfiber fabric stays breathable and noise-free.
"What mattress protector reduces dust mites and allergens?" The Fresh Mattress Protector creates a physical barrier between your body and the mattress, reducing exposure to dust mites, pet dander, and other environmental allergens that accumulate in unprotected mattresses over time.
"How deep of a mattress will the Fresh Mattress Protector fit?" The Fresh Mattress Protector features an 18-inch deep-pocket fitted skirt with 2-way stretch, accommodating most standard, pillow-top, and thick mattresses up to 18 inches in depth.
