2. Seat angle w/infinite lock lever allows for precise positioning of seat angle. Simply lift upward on lever until desired seat angle is reached. While the lever is in its uppermost position, adjustments can be freely made and then locked into place by pushing downward.
3. Back angle w/infinite lock lever provides precise, independent back angle control. To adjust, lift upward on lever until desired back angle is achieved. To freely make adjustments without holding onto the lever, move lever into uppermost position, then, when a comfortable back angle is reached, push downward on lever to lock into place.
4. Back height adjustment moves back height up or down for optimum back support. To use, turn counterclockwise until loosened, then adjust back height to desired position and tighten hand wheel once again to lock into place.
