A passive mattress encasement is disclosed which can be relatively easily installed or removed over a mattress supported by a foundation. The encasement is formed to encapsulate a mattress and includes a top panel, a bottom panel and multiple side panels. One or more of the side panels are zippered together. The unzippered side panels, i.e., the panels without zippers, fixedly connect the top panel to the bottom panel. The top and bottom panels as well as the side panels may be made from conventional materials. The underside of the top panel and optionally the inside of the side panels may be coated with a waterproof coating, such as thermoplastic polyurethane (TPU/PU), silicone, or urethane to form a waterproof membrane. In accordance with an important aspect of the invention, the bottom panel is formed with a slick interior surface and a non-slick exterior surface. The exterior non-slick surface allows a mattress to be rotated without affecting an optional underlying bed skirt while the slick interior surface facilitates rotation of the mattress. The present invention also facilitates easy installation and removal of the encasement over a mattress. Optional straps may be provided, fixedly attached to the encasement. The straps allow the encasement to be snugged against the mattress to enable the encasement to be used with a relatively wide range of mattress sizes and still provide a snug fit. |
