What you get

Top: polyester fabric.
Closure: locking zipper.
Covers all six sides of the mattress or box spring.
Waterproof, as the maker states.

How to use it

Measure the mattress from the bottom seam to the top, pillow-top included.
Zip the cover shut all round, and close the end of the zipper the way the maker shows.
Leave it on: bed bugs zipped inside die there in time.
Check the cover for holes and tears when you change the sheets.
Pair it with interceptor cups: a cover does not stop a bug from climbing onto the bed.

Will it fit?

Sizes: Twin, Full, Queen, King. The maker prints no depth for this cover: measure your mattress and check the size label before you open the package.

Find the cover for your bed size and depth.

Double zipper encasement with a sealed end

Two zippers meet at a sealed end on this encasement, a layout the maker uses to close the gap a single zipper can leave. Once you zip it shut, bugs already inside the mattress stay inside. The top is smooth and waterproof against spills and sweat. Sizes are Twin, Full, Queen and King.

The body is a stretchy fabric that takes up differences in mattress depth and stays taut instead of bunching as you sleep. The maker suggests pairing it with its own box spring encasement and ClimbUp interceptors under the legs, so your whole bed is closed off from the floor up.

JT Eaton Lock-Up Total Encasement is part of the Bed Bug Blocker collection, on the mattress encasements shelf.

How to use the JT Eaton Lock-Up Total Encasement follows the EPA and the University of Kentucky: zip it shut, leave it on for a year, and stand the bed legs in cups.

This is general information about keeping bed bugs out of a bed, not pest control or medical advice. A licensed pest professional, your doctor and the maker's own instructions come first.

What the public sources say

U.S. EPA, "Do-it-yourself Bed Bug Control". Says to set interceptors under each leg of infested furniture, move it a few inches off the walls with no linens touching the floor, check and clean the interceptors every week, keep inspecting at least every 7 days, and use covers that seal mattresses and box springs so bed bugs inside die. Read October 30, 2026.
University of Kentucky Entomology, ENTFACT-636 "Bed Bugs". Says bed bugs zipped inside an encasement eventually die, that an encasement does not stop a bug from climbing onto the bed, that a trap under each leg with the bed pulled off the wall makes the bed an island, and that a dryer at medium-to-high heat for 10 to 20 minutes kills all life stages.
