How do I adjust the OptiLife?
First, adjust the side straps to move the cushion snugly and comfortably into place. Then, adjust the chin support band so that it rests snugly on the chin. Do not over tighten the straps. Finally, rotate the cushion on the hub for a comfortable fit. If the side straps are resting on the ears, tighten the top strap to move the side straps off the ears, then readjust the side straps, chin support band and cushion. This web site provides several tools to help you adjust to the OptiLife mask.
