A head-mounted device may have a head-mounted support structure that is configured to be worn on a head of a user. The head-mounted support structure may include a flexible rear portion that at least partially defines a central opening through which the displays in the head-mounted device are viewable. The flexible rear portion may conform to a face of the user when the head-mounted device is worn by the user. A removable cushion may be selectively attached to the flexible rear portion of the head-mounted support structure. The removable cushion may conform to and directly contact the face of the user when the head-mounted device is worn by the user. The removability of the cushion may allow for the cushion to be easily cleaned, easily replaced when worn, and customized to a user's aesthetic and comfort preferences.
