Frequently Asked Questions

What’s the difference between a mattress protector and an encasement?

A standard mattress protector covers just the sleep surface and sides, while a full 360° encasement seals all around—including the bottom—creating a complete barrier. This level of protection is especially effective against allergens, dust mites, bed bugs, and moisture.

Can an encasement really keep out bed bugs and dust mites?

Yes. When properly fitted and fully zipped closed, a high-quality encasement like Encase HD traps and prevents bed bugs and dust mites from entering or escaping the mattress. This containment helps interrupt infestations and reduces allergen exposure.

Will the encasement change how my mattress feels or sleep on it?

Not with our smooth polyester top panel. It remains breathable and soft under your sheets while staying quiet and wrinkle-free—unlike cheaper plastic-style encasements that often rustle or feel stiff.

How do I clean the Encase HD Protector?

Simply unzip and remove the top panel—no need to take off the entire encasement. Machine wash on cold, tumble dry on low. Do not bleach or dry clean. This makes regular use and deep cleaning hassle-free.

Will using an encasement void my mattress warranty?

No—in many cases, using a waterproof encasement actually protects your mattress warranty. Avoiding stains or damage from spills helps preserve your mattress and keeps warranty claims valid.

Where can I buy an encased mattress protector near me?

The Encase HD 360 fully encased mattress protector is available in store across Oklahoma with same-day delivery. You can also order online for next-day delivery to most Oklahoma addresses. Financing is available through Affirm, Snap, and Synchrony.

Is this a heavy duty mattress protector?

Yes. The Encase HD 360 is designed for heavy duty everyday use. The Micro Tite zipper, H2Pro waterproof membrane and fully enclosed six-sided construction make it one of the more durable encased mattress protectors available, suitable for mattresses up to 22 inches tall.

What is the H2Pro liquid-proof membrane?

H2Pro is a waterproof membrane built into the mattress protector that blocks liquid from reaching your mattress while still allowing airflow. It protects against spills, accidents, sweat and other liquids without the plastic crinkle sound of traditional waterproof covers.

Is this mattress protector compatible with an adjustable bed?

Yes. The Universal Fit sides and flexible encasement design make the Encase HD 360 compatible with adjustable bases. The fully enclosed construction stays securely in place even when the head or foot of the base is raised.

What sizes does the Encase HD 360 mattress protector come in?

The Encase HD 360 fully encased mattress protector is available in twin, twin XL, full, queen, king, and California king. All sizes feature the same six-sided protection, Micro Tite zipper, and H2Pro waterproof membrane.
