A floor cushion with a seat back has excellent ease of storage and is designed to improve heat preservation by adjusting the cushion size to a chair or increasing its fitting property. The floor cushion includes a sheet-like seat portion, a sheet-like seat back portion foldably connected to a rear part of the seat portion, and sheet-like sleeve portions foldably connected to both sides of the seat portion. The sheet-like portion extends at a required length beyond the rear part of the seat portion, and extensions of the respective sleeve portions are attached to the back face of the seat back portion, thereby enabling fixing of the respective extensions and the seat back portion to each other, detachably and in a way to allow positional adjustment with hook-and-loop fasteners.
