Abstract
Abstract A mattress cover made of a length of thin waterproof plastic sheet material which covers a bassinet mattress with a waterpervious sheet across the top of the plastic sheet having edge portions bonded to the plastic. Plies of cellulose wadding may be used between the water-pervious sheet and the plastic to provide additional cushioning and/or absorbency. Parts of the plastic extend under the mattress to hold the cover in place. One modification is tubular for receiving the mattress and another has diagonal slits near the corners of the cover so that the mattress corners can be put through the slits to hold the cover on the mattress.
