Key Features of Our Mattress Encasements for Bed Bugs

Six-Sided Coverage

Wraps the top, sides, and underside of your mattress, not just the sleep surface.

Zips Fully Closed

A three-sided invisible zipper closes the encasement all the way around your mattress.

An Extra Layer of Defense

Can help protect your mattress as one part of a complete bed bug plan.

Waterproof Barrier

Reinforced seams and a waterproof layer help guard against spills and stains too.

Fits Up to 18" Deep

Stretchwick 3.0 stretches for a snug fit while keeping your mattress's original feel.

Machine Washable

Machine wash cold and tumble dry low to keep your encasement fresh.

How a Mattress Encasement Can Help With Bed Bugs

Bed bugs like to hide in mattress seams and box spring corners. A fitted protector leaves the underside open, while a zippered encasement covers all six sides. The EPA's bed bug guidance includes encasements as one step in a broader plan, alongside inspection and professional treatment.

Our Stretchwick® Mattress Encasement adds that six-sided layer with a waterproof barrier and a frictionless feel. It isn't a treatment, so if you already have bed bugs, work with a licensed pest professional and use your encasement as part of the plan.
