10 Best Bed Bug Mattress Encasements 2025 in the United States

The Utopia Bedding Zippered Mattress Encasement for cribs is designed to protect your baby’s mattress from bed bugs, dust mites, and spills. It fits crib mattresses measuring 28 by 52 inches with a 7-inch deep pocket, ensuring a snug fit. Made from stretchable knitted polyester fabric, it offers a comfortable sleeping surface while adapting well to the mattress shape. The zipper fully encloses the mattress, providing 360-degree protection to keep pests and liquids out.

Its TPU backing guarantees 100% waterproofing, helping prevent any leaks from reaching the mattress. The encasement is also easy to care for, as it can be machine washed and tumble dried, which is convenient for busy parents. While the polyester material is durable and waterproof, it may not be as breathable as natural fabrics, so some airflow might be limited.

This encasement is a practical choice for crib owners looking for reliable bed bug and waterproof mattress protection that’s easy to maintain and fits well.

The King SureGuard Mattress Encasement is designed to fully protect your mattress from bed bugs, liquids, and allergens, making it a solid choice for anyone looking to safeguard their sleep environment. Its six-sided zippered design with a super fine zipper and SureSeal technology ensures a tight seal against bed bugs, which is crucial for effective protection. The material is a soft cotton terry fabric, which feels comfortable and helps wick away moisture, avoiding that plastic-like feel some encasements have. It also blocks dust, dirt, and allergens, which can be a big help if you suffer from allergies.

The waterproof feature is robust, protecting against spills or accidents, though for heavy or frequent wetness, adding a separate mattress protector on top is recommended. The zipper quality is premium and designed to avoid gaps, but some care is needed to ensure the zipper stays smooth over time. With a size fit for mattresses 13 to 16 inches deep, it suits thicker mattresses well. Cleaning is easy since it’s machine washable and dryable, which is convenient for regular maintenance.

While the cotton terry top improves comfort and breathability compared to vinyl covers, it may not be as cool for very hot sleepers. Also, the encasement doesn’t come in colors beyond white, which might matter for some users. This encasement offers reliable, hypoallergenic, and thorough mattress protection, making it a good pick for those especially concerned about bed bugs and moisture without sacrificing comfort.

This Full Size Mattress Protector from Four Seasons Essentials offers strong protection for your mattress with a six-sided zippered design that fully encases your mattress. The zipper is secure with a Velcro seal, helping to keep bed bugs, dust, and pet hair out. Made from soft polyester with a waterproof polyurethane lining, it keeps liquids from reaching your mattress, which is great if you have kids or pets. It’s also designed to be quiet and comfortable under sheets, so you won’t hear crinkling noises while you sleep. The fabric is breathable, helping to reduce heat build-up, which makes it more comfortable than some other waterproof covers. Installation is straightforward thanks to the zipper that goes around three sides, fitting mattresses between 9 and 16 inches thick.

Cleaning is easy since it’s machine washable and durable enough to last through many washes. While the zipper quality is good and sealed with Velcro, some users might find that zipping around the mattress takes a bit of effort. Also, since the product dimensions are compact for shipping, unfolding it might require some time to settle fully. The white color is standard but may show stains or dirt more easily, so regular washing is important. This encasement is ideal for anyone wanting full bed bug protection combined with waterproofing and hypoallergenic features, especially if you need a comfortable, quiet cover that won’t disturb your sleep.
