Abstract: A flotation pool blanket for covering a swimming pool adapted to be gathered when removed, said flotation pool blanket defining a blanket covering the water of the pool having at spaced intervals, parallel ribs underlying the blanket, the ribs at each end rising up to form ears which overlap and engage the top of the pool decking surrounding and defining the pool. Further, the ears provide means by which the flotation pool blanket may be gathered up for removal by starting at one end, picking up the rib, proceeding to the next rib and repeating the step until all the ribs have been picked up at which time the blanket and the ribs carried to a position away from the pool. Emplacement of the invention pool blanket is just the opposite of removal, the operators dropping one end of the flotation pool blanket in the pool and then proceeding to let out a rib as they traverse the length of the pool.
