Experience the Comfort & Protection of Our #1 Selling Mattress Protector
There’s are several reasons this is our top-rated mattress protector. If is made from luxuriously soft 100% GOTS-certified organic jersey cotton that is breathable, eco-friendly & waterproof. It also protects all five sides of your mattress, not just the top, the sides are protected too. Thousands have made it their go-to choice for everyday comfort and dependable eco-friendly protection.
Why Our Organic Cotton Mattress Protector Stands Out:
-
Five-Sided Coverage: Unlike most protectors that only guard the surface, ours goes the extra mile—shielding the top and all four sides from spills, allergens, and bacteria.
-
Double-Layer Design: A dual layer of ultra-soft organic jersey cotton combined with our exclusive, biodegradable Thermoplastic Polyurethane (TPU) barrier provides flexible, quiet protection that never compromises comfort.
-
Effortless Care: Just toss it in the wash. Our protector is machine-washable and designed to maintain performance over time.
Designed for a Better Fit, Naturally
We’ve refined our production process to account for the natural tendencies of organic cotton. That’s why our protectors are made a bit roomier—about 2–3 inches wider than standard sizes—to ensure a perfect fit after the first few washes. We don’t use harsh chemical treatments to control shrinkage, so you can enjoy bedding that’s as pure as it is practical.
Tip: For best results, wash your protector before first use. You may notice some shrinkage within the first 2–5 washes, but it will never shrink below standard mattress dimensions.
Eco-Conscious, Inside and Out
Our signature waterproof layer is made from a non-GMO, corn-starch-based TPU. It’s not only biodegradable but also gentle on both your skin and the planet.
For Split King or Split Cal King Setups
Have a split mattress setup? Be sure to order two protectors to cover each side individually.
Why You'll Love It
If you or a loved one deals with allergies, asthma, or sensitivities to chemicals, this protector was made with you in mind. It’s 100% hypoallergenic, free from harsh substances, and offers five-sided, fully waterproof protection against spills, pet messes, and little accidents.
Sleep soundly without the sticky, sweaty feeling—our breathable, organic jersey cotton stays cool and comfy all night. And with a silent, crinkle-free design, you’ll barely notice it’s there.
