• an inflatable rim integrated with the body, the rim comprising:
• a top surface configured to contact an underside of a pool lip;
• and
• a bottom surface configured to rest on the surface of the pool water;
• wherein the inflatable body is configured to form a continuous seal beneath the pool lip and distribute the weight of external forces across the inflatable, dome-shaped body to prevent sagging or displacement.

A method of using an inflatable pool cover device, the method comprising the following steps:

• providing an inflatable pool cover device comprised of a dome-shaped, inflatable body, an inflatable rim integrated with the body, and an air valve;
• positioning the dome-shaped, inflatable body on a surface of a pool water such that a perimeter edge of the dome-shaped, inflatable body aligns with a perimeter edge of the pool and the inflatable rim aligns beneath a pool lip;
• attaching an air pump to the air valve;
• and
• inflating the dome-shaped, inflatable body until the inflatable rim expands outward and upward, forming a continuous seal with the underside of the pool lip while the bottom surface of the rim rests on the surface of the pool water.
