A pool cover support comprises a balloon for placement in its uninflated condition on the surface of the water in a swimming pool, an air hose having one end attached to the balloon and provided at its other end with a valve. The hose is of sufficient length that when the balloon is secured in a predetermined position, the valve can be located outside the pool, whereby the balloon can be inflated or later deflated. A covered pool has an edge and is filled with water. A pool cover covers the pool and overlaps the pool's edge, and a pool cover support comprises a balloon which is in a predetermined position on the water and underneath the cover, an air hose having one end attached to the balloon and a valve at its other end. The hose is sufficiently long that the valve is outside the pool, whereby the balloon can be inflated or later deflated with the cover in place. A method of covering a pool utilizes a cover support including a balloon and comprises the steps of placing a cover over the pool and the balloon and thereafter pumping air into the balloon to change same to its inflated condition.
