A door urging apparatus, for use with an existing door hingedly mounted in a frame, the door moving between a closed, a crossover, and open states, the door urging apparatus including an offset bracket with a base and an arcuate planar element having a proximal end that extends from the base and a distal end with a first pivotal attachment. Also included is a plate affixed to a frame portion opposite of the hinged mount, the plate having a second pivotal attachment. Further included is a gas spring assembly having a lengthwise cylinder with a telescoping rod, the gas spring provides a dampened force extending the rod outward. The gas spring is pivotally attached between the first pivotal attachment and the second pivotal attachment, wherein operationally the door is urged into the open state by the gas spring and is also urged into the closed state by the gas spring.
