How do I attach the cushion to the OptiLife?
To ensure correct placement of the cushion, match the arrow on the cushion with the arrow on the interface. The arrow on the cushion and the arrow on the interface should be on the same side, but they do not need to be aligned perfectly. Attach the cushion to the cushion attachment hub one side at a time. Place a hole on the side of the cushion over the corresponding post located on the hub. Then, stretch the cushion over the hub to attach the other side.
