How is a Mattress Encasement different from a Mattress Protector?
Unlike a traditional Mattress Protector, which fits only over the top surface of your mattress, a Mattress Encasement fully encloses your mattress and securely zips shut, providing 360° protection.

The Mattress Encasement can fit over mattresses from 10-16 inches in height, providing 360° protection against spills, stains, and more!
Is the Waterproof Mattress Encasement machine washable?
Yes, the Mattress Encasement includes quick and easy care! We recommend machine washing your Mattress Encasement on a cold, gentle cycle with like colors. Please do not dry clean, bleach, or iron, as these can damage the waterproofing layer. For small spills, we recommend spot cleaning with cold water and a mild household detergent or diluted cleaner.
How do I arrange the Mattress Encasement on my mattress?
We recommend adding your Waterproof Mattress Encasement directly over the surface of your mattress and then adding your sheets and bedding on top. The Mattress Encasement will provide complete waterproof coverage beneath your bedding.
