A combination doorbumper and doorstopper includes a mounting plate, spindle, bumper, toggle bolt, and toggle bolt anchor. The doorbumper is installed on a wall so that a doorknob or door handle will engage the bumper when the door is fully opened. The spindle is positioned between the mounting plate and the bumper, and includes a narrow neck region. The door can be held in an opened position by placing a loop end of a flexible cord over the doorknob or handle on the opposite side of the door from the doorbumper, and stretching the cord so that a hook at the opposite end of the cord can be placed over the neck of the spindle. The doorbumper together with the flexible cord acts as a doorstopper to hold the door open.
