Product description

Size:Twin XL

Your bed is an expensive investment-why not protect it? Shield your box spring from bed bugs, dust mites and allergens.

The Sleep Defense System by Hospitology Products brings Hotel and Healthcare caliber bedding protection to your home. Featuring extra-tough seam construction and high thread-count polyester knit fabric. Ultra-plush knit fabric is soft to the touch. Fully breathable-does not trap heat and is cool to sleep on.

Bed bugs are infesting homes and apartments at an alarming rate and mattress encasements are an effective defense. Help ease asthma and other respiratory symptoms by preventing allergens, dust mites and bacteria from reaching the sleeper. This encasement will accommodate a box spring height of 8"-9”. It is fully machine washable and dryable, or you may simply wipe it clean with a damp cloth. It is fully zippered on 3 sides and features Allergy Blocker to prevent allergens from exiting through the zipper. Bug Flap and Zipper Lock ensure that your box spring encasement remains bed bug proof for the life of your mattress.

Size: TwinXL (38"x80"). Fits Box Springs 8”-9” Deep.

Machine washable, Tumble Dry Low or No Heat. Please follow all included care instructions to maintain your mattress encasement’s warranty.

Contains no Vinyl, PVC, or Phthalates, or Fire Retardant Coatings of any kind.

Includes a 5-year limited manufacturer’s warranty.
