Bugstop Mattress Covers - Bed Bug Bite Proof, Dust Mite Proof and Water proof

The exterior is made of Polyester stretch knit.  The entire interior membrane is covered with polyurethane.  We use a special tight zipper with very tiny teeth, an interior flap and an exterior seal that does not allow bed bugs in or out even if the zipper is not 100% zipped.
Our encasements have no seams, pockets or folds.  The covers need only to be washed every 3 to 4 months if there is no bed bug problem.  Between washings, simply wipe down with a damp cloth or vacuum with each linen change.  Use hot water to wash do not use bleach and dry on medium heat.

Covers come in 4 mattress thicknesses, but each cover will stretch up to 2".
