The present bed bumper apparatus includes an elongate body that is resilient and flexible, an inner cover enclosing an entirety of the elongate body such that the elongate body is removable from the inner cover only by destroying an integrity of the inner cover, an outer cover enclosing an entirety of the inner cover having the elongate body, and a flexible strap engaged to the outer cover and having a quick release buckle and length adjuster such that the bed bumper can be engaged to a mattress at an edge of the mattress to minimize a person from rolling off the mattress.
