Look No Further than a SureGuard Mattress Encasement.

SureGuard Mattress Encasements provide 360 degree premium protection against liquids, stains, allergens and bed bugs. They are ideal for those with pets or children, or anyone suffering from bedbug infestations, incontinence, asthma or dust mite allergies.

Leaving your mattress unprotected from just one bedtime accident can result in a permanent bed stain or odor, which can be near impossible to remove. A SureGuard six-sided waterproof mattress protector will provide lasting protection for your mattress, giving you peace of mind and a healthier sleep surface for you and your family.

Premium Protection on all Six Sides

100% Waterproof

With SureGuard you no longer have to worry about spilled drinks, potty training accidents or messy pets ruining your mattress.

Our waterproof mattress cover provides six-sided protection against perspiration, urine, liquids and stains - prolonging the life of your mattress.

The soft 100% cotton terry top surface naturally absorbs liquids and moisture, while regulating the temperature of your sleep surface, making it ideal for those that sleep hot or suffer from night sweats.

The breathable, noiseless waterproof backing blocks liquids while allowing body heat and air to circulate through, keeping your mattress cool and dry.

(Helpful tip - For frequent accidents and easy clean-ups, place a fitted SureGuard Mattress Protector over the encasement.)

Blocks Bed Bugs

Bed bugs love to hide in mattresses where they can multiply and feed off your blood while you sleep. This causes a widespread problem for the millions of us with unprotected bedding.

SureGuard's advanced membrane blocks bedbugs from entering your mattress. The bite proof barrier also prevents bed bugs from escaping an infested mattress.

The super fine zipper with Invisi-Zip and SureSeal technology completely seals off the mattress from bed bugs, so that you can have a more restful night's sleep.

(Helpful tip - Use together with SureGuard Pillow Protectors and a Box Spring Encasement for added protection. No need to throw out your favorite bedding.)

Hypoallergenic

SureGuard's hypoallergenic backing blocks dust mites, allergens, bacteria, mildew and mold from entering your bed. The thin light-weight mattress pad reduces your nighttime allergies without changing the feel of your mattress.

The mattress protector is compatible with just about any type of mattress, including pillow top, innerspring, memory foam, latex, inflatable beds, sleeper sofas, foldable and portable mattresses. It should work on any mattress that can be removed from the bed frame and is not connected to any hoses or hose attachments.

(Helpful tip - Line drying the SureGuard in direct sunlight for at least 4 hours will naturally kill dust mites and allergens left in the cover after the wash cycle. No need to use high heat or anti-allergen sprays.)

Durable & Easy to Clean

Just pop it in the machine.

How often to wash?

  • General protection - every 2nd month or after each accident
  • Allergy prevention - every month or when allergies flare up.
  • Bedbug protection - keep on infested mattress for at least 1 year to ensure bed bugs die from starvation.

(Helpful tip - Wash and dry before first use to open up the cotton terry loops and maximize softness and absorbency.)

  • Washing - Machine wash separately in cool water with a mild detergent (no bleaching agents).
  • Drying - Tumble dry on a low or no heat setting with sheets or towels. For allergy sufferers, line dry in direct sunlight to naturally kill allergens left in the cover after the wash cycle.
  • Wash and dry unzipped with material side facing out.
