A respiratory mask assembly includes a respiratory mask including a mask shell and a mask cushion, a forehead support adjustably coupled to the mask, and an angular adjustment member. The forehead support includes a joining member provided to the mask shell and a cushion frame pivotally mounted to the joining member. The cushion frame is adapted to be selectively locked against pivotal movement in at least three predetermined angular positions relative to the joining member by a tongue and slot arrangement. The angular adjustment member allows relative angular adjustment between the cushion frame and the joining member. The angular adjustment member includes a pair of flexible arms that are adapted to be flexed towards one another to disengage the tongue from a respective one of the slots, and releasing the flexible arms allows the flexible arms to resiliently flex away from one another to engage the tongue and the respective slot.
