UltraBlock® Cotton Waterproof Mattress Protector

Highest Quality

The UltraBlock® line of cotton waterproof mattress protectors are made using only the highest quality hypo allergenic materials. Protect your mattress from expensive spills while protecting your family from allergens and dust mites lurking in your mattress.

Sleep Cooler

Our breathable, super-flexible membrane with Micropore technology allows air to flow thru to keep you cool, but blocks out liquids, moisture, and spills. Allergens and dust mites can not penetrate the micropores, so your family can sleep safe. Our products feature an antimicrobial coating to protect fabric from deterioration, odors, bacteria, mildew, and microorganisms.

More Comfortable

Most other mattress protectors are made with a waterproof membrane that isn’t very flexible or comfortable. Our new UltraBlock™ Mattress Protectors are flexible and quiet and won’t change the feel of your mattress, perfect for memory foam beds. Backed by a full 20 year product replacement warranty.
