ABSTRACT:
A set of sheets includes an upper sheet with a top panel and a lower sheet with a bottom panel. In conjunction, the upper and lower sheets are sized, structured and configured to enclose a mattress. A waterproof panel is positioned between the upper sheet and the top of the mattress to protect the mattress from damaging exposure to moisture and liquids, including bodily fluids. In several embodiments, the upper sheet and waterproof panel are removable for washing and changing thereof while the lower sheet remains fitted to the mattress, thereby avoiding the need to lift or move the mattress when changing the sheets. The waterproof panel may be independently removable to selectively control air permeability of the sheets, and particularly the upper sheet. In a further embodiment, a minor waterproof panel is removably attachable in covering relation to a portion of the top surface of the upper sheet to protect the upper sheet and mattress from becoming soiled, and thereby extending the period of time between laundering and changing of the set of sheets.
