Abstract: A portable foldable stadium seat storing a roll-down rain cover. The stadium seat has a back structure pivoted to a bottom seat member and presenting front and rear members spaced apart front-to-back by laterally spaced legs of the frame of the back structure. A spring-wound, window shade-type roller is rotatably mounted between these frame legs below the front and rear members of the back structure. A folded fabric rain cover is wound on the roller and extends up between the front and rear members and the laterally spaced legs of the frame of the back structure. A stick extends through a loop at the upper end of the rain cover and engages upwardly-facing shoulders on the legs of the frame when the rain cover is wound on the roller. A manually operable brake holds the roller against rotation after the rain cover is unwound and pulled up to a raised position above the back structure.
