A single-use disposable sanitary cover temporarily houses a portion of a seat and mitigates virus and germ contact on a person's body. The disposable sanitary cover includes a flexible elongated sleeve having an outer shell, an interior cavity and an elongated slit forming a rim equipped with a stabilizing means integrally associated therewith. The stabilizing means is preferably an elastic band or segment that engages with the rear of the back support and seat areas of the chair to secure the elongated sleeve in place. The seat area and/or back support area of the chair is received through the elongated slit and is housed within the elongated sleeve in order to mitigate contact between the chair surface and a person's body.
