Front Seat Adjustment
The seat can be adjusted forward or rearward by using a
bar located by the front of the seat cushion, near the floor.
While sitting in the seat, lift up on the bar located under
the seat cushion and move the seat forward or rearward.
Release the bar once you have reached the desired
position. Then, using body pressure, move forward and
rearward on the seat to be sure that the seat adjusters
have latched.
