Abstract: Four substantially parallelopiped cushions are provided and disposed in end-to-end relation and positionable on a plane surface with either first or second corresponding face surfaces of the cushions opposing the plane surface. Each pair of adjacent cushion ends are connected together for relative angular displacement about a transverse axis extending along corresponding end transverse marginal portions of the first corresponding face surfaces of the cushions. Three adjacent cushions of the four cushions are of generally the same length while the fourth cushion is of a length equal to approximately one half the length of each of the other three cushions.

Abstract: An elongated channel member is provided including a first open longitudinal side outwardly of which said channel member opens and a second remote side defining a planar abutment surface disposed normal to the direction in which the first side of the channel member opens. The planar abutment surface has adhesive structure supported therefrom whereby the planar abutment surface may be abutted against and adhesively secured to a tub-shower stall wall extending upwardly from one end of the outer side wall of an associated tub and the open side of the channel member has one longitudinal edge portion of an upstanding panel member secured therein.
