These 100% bed bug proof zippered box spring encasings are lab-tested and certified to *completely* block bed bugs. While bed bugs can quickly bite through normal bedding, they will not bite through these box spring encasings. In addition to bed bugs, absolutely no dust, dust mites, dust mite allergens, or any other danders or allergens can pass through the fabric.
Bed Bug Proof Encasings fit box springs as well as mattresses and are available in standard 9 inch depth or low profile 7 inch depth sizes. If you are unsure which depth encasing you need, it is always best to get the deeper encasing, as you can always tuck in any extra material underneath the mattress. Bed bug encasings may tear during installation if the box spring is slightly too deep. Please carefully measure the depth of your box spring to determine which depth encasing you should order.
