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.
