Said panel provided with a least two side drops and one end drop. Said side and end drops coupled at one margin with said panel and at a spaced parallel margin with triangular corner pieces at each end of said end drop. The couplings, drops, panel corner and triangular corner piece cooperating by geometric shape and joinder to form margins defining a pocket and pocket aperture through which the mattress or bladder corner may be manually drawn. At least the corner piece to be formed from top panel material cut on the bias for elasticity. Said aperture margins containing water surge therethrough sand preventing mattress withdrawal therefrom.
