20120137434 | Mattress Encasement - A mattress encasement and method protect against the migration of bed bugs into and out of a mattress. The mattress is encased within encasement members constructed of a material resistant to the migration of bed bugs through the material. The encasement members are joined together along perimetric edges by the engagement of a zipper provided with a peripheral length greater than a perimetric length of each perimetric edge. With the zipper engaged fully along its peripheral length, the difference between the peripheral length of the zipper and the perimetric lengths overlaps an inner segment of the zipper adjacent one terminal end of the zipper with an outer segment of the zipper adjacent the other terminal end of the zipper, to complete a barrier against the migration of bed bugs into and out of the encased mattress through either one of the terminal ends of the zipper. | 06-07-2012 |
