Quick Summary: Bed Bug Mattress Encasements

A certified, lab-tested mattress encasement is the single most critical defense line in bed bug eradication. By completely sealing your mattress and box spring in heavy-duty, bite-proof polyurethane-backed fabric with micro-zipper locks, you trap existing bugs inside to starve and prevent new colonies from establishing.


Standard fitted sheets leave your mattress exposed on all sides, allowing bed bugs free access to inner padding and stitching tufts. Installing a certified, bite-proof encasement creates an impenetrable physical barrier that simplifies daily inspections and protects your investment. Pair your encasement installation with regulating indoor humidity and sealing bedroom baseboards for complete home defense.

Below is an overview of encasement selection criteria, a product comparison matrix, and installation guidelines.

Why Certified Encasements Are Essential for Bed Bug Control

Bed bugs cannot bite through thick polyurethane and tightly woven micro-fibers. Encasements serve two vital purposes: trapping any bugs and unhatched eggs already inside the mattress so they eventually die of starvation (taking up to 400 days for adults), and providing a smooth, white surface where new hitchhiking bugs are instantly spotted during visual inspections.

Top 4 Mattress Encasement Features to Evaluate

Verify these four essential criteria before purchasing:

  1. Micro-Zipper Lock Design: Specialized tooth-locking zippers that prevent bugs from crawling out through the zipper pull opening.
  2. Six-Sided Protection: Full enclosure covering top, bottom, and all four sidewalls rather than a top-only fitted sheet style.
  3. Breathable Waterproof Membrane: Polyurethane backing that blocks liquid spills and sweat while allowing air circulation to prevent heat buildup.
  4. Lab-Tested Bed Bug Certification: Independent laboratory verification proving fabric pore size is too small for nymphs to penetrate.

Step-by-Step Installation and Sealing Protocol

Pro Tip: Never Remove the Encasement for at Least One Year

Once you zip your mattress inside the SafeRest Encasement, leave it sealed for a minimum of 12 to 18 months. Bed bugs can survive extended periods without feeding, and opening the cover prematurely risks letting surviving adults escape.

  1. Strip and Treat the Mattress: Vacuum and steam all mattress surfaces to eliminate surface bugs before encasing.
  2. Enlist a Second Person for Lifting: Stand the mattress on its side to make slipping the cover over the corners much easier without tearing fabric.
  3. Pull the Cover Down Gradually: Work the SafeRest Encasement downward over all four corners like a giant pillowcase.
  4. Zip Completely and Seal Velcro Flap: Pull the micro-zipper shut, ensuring the locking mechanism clicks into place, and press the protective Velcro flap firmly over the zipper pull.
  5. Inspect Box Springs Separately: Repeat the exact same encasement process for your box spring foundation to eliminate dual hiding spots.
