Sleep Healthy, Live Healthy. Bed Bugs have become one of our nations biggest epidemics. They infest your mattress and surroundings, feed on you at night and can potentially cause a number of health effects including skin rashes, psychological effects and allergic symptoms. A HealthGuard Mattress Encasement should be a central part of your bedbug control strategy. Putting one on your mattress and one on your box spring is the best defense against infestation. The HealthGuard Bed Bug Encasement fully encases your entire mattress and/or box spring for total protection. It is constructed with a breathable advanced tight fitting stretch knit fabric so you can add your choice of mattress pads/protectors without adding extra bulk and to promote better sheet fitment. It easily slides on and off and seals with a Velcro self-locking zipper and internal flap for an added level of security. Conveniently machine wash and dry.
