A case for a portable electronic device (PED) is disclosed. The case includes a body having an interior surface configured to accept a PED and an exterior surface to be exposed to outside forces. A back vent that permits the transfer heat away from the PED and to the environment presents through the body of the case. A cushioning member is placed at or near the back vent on the interior surface of the case and may substantially or completely surround the back vent. When a PED is placed within the case, the fit of the PED and the case causes the cushioning member to press against the PED in order to create a cushion for the PED in the event of an outside force being applied to the case. The case may include a screen protector within a frame that attaches to the body.
