An ergonomic, passive exercise apparatus with elements and attachments emphasizing benefits to the user's head, neck and back muscles. The apparatus is a chair to which an adjustable dual roller headrest is joined. The headrest is adjustable vertically, laterally, with each roller virtually independent of position and orientation with respect to the other. Adjustable drag to rotation and lateral movement is provided for the user to work against while exercising. in addition, removable, location adjustable pairs of disks may be attached to the axles or rollers. The disks extend outward from the rollers to engage the back of the user's head. The disks are of a resilient material and resist rotation of the user's head when in contact with the disks.
