The CleanRest PRO Max bed bug blocking mattress encasement represents CleanBrands’ approach to maximum waterproofing. It also offers maximum spill protection and bed bug protection while promoting a cool and comfortable night’s sleep. PRO Max has four sides of waterproofing on the top, bottom, and long ends. Because waterproof fabric traps air, CleanBrands designed PRO Max with vented ends at the head and foot to allow warm air to escape the mattress and thus avoid the problem of trapping air, which can create a hot and uncomfortable sleep experience. Free samples are available.
