A mattress or box-spring encasement comprising:

• a cover having an opening to allow a mattress or box-spring to be inserted within an interior of the cover;
• a zipper coupled with the opening;
• a zipper mechanism slidable along the zipper to couple opposing teeth of the zipper to allow the opening to be zipped closed to enclose the mattress or box-spring within the cover;
• a first flap foldable and securable over a distal end of the zipper to cover the zipper mechanism when the opening is zipped closed;
• a barrier material coupled with the first flap such that when the flap is secured over the distal end of the zipper, pressure is applied to the zipper;
• and
• a second flap foldable and securable over the first flap such that when secured, the second flap extends fully around the first flap.
